- Q:can anyone help me to find any webpage about lists/types of stainless steel?
- Types of stainless steel There are over 150 grades of stainless steel, of which fifteen are most common. The AISI (American Iron and Steel Institute) defines the following grades among others: - 200 Series—austenitic iron-chromium-nickel-manganese alloys - 300 Series—austenitic iron-chromium-nickel alloys Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Type 303—free machining version of 304 via addition of sulfur Type 304—the most common; the classic 18/8 stainless steel Type 316—Alloy addition of molybdenum to prevent specific forms of corrosion - 400 Series—ferritic and martensitic alloys.
- Q:Is steel easier to weld?Which is more brittle/less flexible?
- Note: the easiest way to join steel to aluminum is to drill holes and BOLT them together...... You cannot WELD steel to aluminum.(except using extreme methods like explosion welding......) For all intents and purposes they are dissimilar metals, meaning they will not bond to each other. Also, aluminum has a much lower melting point than steel. It is possible to join steel and aluminum by *Soldering,* using tin/zinc hard solder. This requires a special flux designed exclusively for soldering aluminum though. The heating process is also a bit delicate as you must avoid overheating the joint. I work as a welder and I've only soldered Al three or four times. Steel is easiest to weld by far. If you set the equipment correctly, a six year-old kid can make a good weld on steel. Aluminum requires special equipment and procedures to weld. It's not easy. The brittleness of aluminum depends on it's alloy content. Most of the aluminum that's used today is not pure, rather it's in the form of aluminum ALLOYS which contain either zinc, magnesium, silicon, or manganese. these elements increase the strength dramatically, but also make it much less ductile. Commercially pure (CP) aluminum is very ductile, but it's also rather weak. Pure aluminum is used to make aluminum foil, as it's so soft and ductile it can easily be rolled paper-thin. The best aluminum alloys can come near in strength to mild steel, but weigh less than half as much as steel. Note that steel itself is an alloy of iron and carbon, Carbon increases the strength of iron in the same way that zinc or magnesium increase aluminum's strength. Most of the commonly used aluminum alloys are somewhat more brittle than mild steel, but not greatly so.
- Q:I've seen on TV that stainless steel laminate sheets can be purchased and and used to cover appliances to give it a faux stainless steel look. They mentioned it was important to not have any bubbles (of course) and to work slowly. It's easy to do on a dishwasher, but what about the fridge? The handles are in the way? Do you have to take the handles off? Can anyone find a tutorial for me?
- There okorder appliance paint 2. What you are referring to really is not laminate steel sheets, it's actually more along the lines of shelf liner paper looks like steel with sticky back film that you peel and stick. Place against product and begin to peel down slowly using squeegee or credit card to smooth out bubbles.Sheets can be purchased rangingin size on OKorder for $9.99 + dependent on size. Called stainless steel appliance film can buy a roll for $60.00 on OKorder (normally sells for $100.00) one roll will cover 3 average sized kitchen appliances. Hope this helps!

- Q:What are the common challenges in steel coil manufacturing?
- Some common challenges in steel coil manufacturing include maintaining consistent quality, managing the weight and size of coils, ensuring proper surface finish, minimizing defects such as dents or scratches, preventing coil damage during handling or transportation, and optimizing production efficiency to meet customer demands.
- Q:How are steel coils protected from mechanical damage?
- Steel coils are typically protected from mechanical damage through the use of various packaging materials such as wooden crates, steel frames, or protective plastic wraps. These measures ensure that the coils remain intact and safeguarded during transportation, handling, and storage, minimizing the risk of any potential mechanical damage.
- Q:What are the different types of surface finishes for steel coils?
- There are several different types of surface finishes for steel coils, each offering its own unique properties and advantages. Some of the most common surface finishes for steel coils include: 1. Hot Rolled: This is the most basic surface finish for steel coils and is achieved by heating the steel and then rolling it to its final shape. It typically has a rough and scale-like appearance, with varying levels of surface imperfections. 2. Cold Rolled: This surface finish is achieved by further processing hot rolled steel coils through a series of cold rolling operations. Cold rolled steel has a smoother and more uniform surface compared to hot rolled steel, with improved dimensional accuracy and better surface quality. 3. Galvanized: Galvanizing is a process in which a protective layer of zinc is applied to the surface of the steel coil. This surface finish provides excellent corrosion resistance, making it ideal for outdoor applications and environments where the steel is exposed to moisture and other corrosive elements. 4. Stainless Steel: Stainless steel coils have a unique surface finish due to the presence of chromium, which forms a thin, invisible layer of oxide on the surface. This surface finish provides excellent corrosion resistance and a visually appealing appearance. 5. Electrolytically Zinc Coated: Also known as electrogalvanized, this surface finish involves the application of a thin layer of zinc to the steel coil through an electroplating process. It provides good corrosion resistance and is commonly used in applications where aesthetics are important. 6. Pre-painted: Pre-painted steel coils have a surface finish that is coated with a layer of paint or other protective coatings. This finish offers both corrosion resistance and aesthetic appeal, allowing for a wide range of colors and finishes to be applied. 7. Aluminized: Aluminized steel coils have a surface finish that is coated with a layer of aluminum-silicon alloy. This finish provides excellent heat resistance and is commonly used in applications where high temperatures are encountered, such as exhaust systems or ovens. Overall, the choice of surface finish for steel coils depends on the specific requirements of the application, including factors such as corrosion resistance, aesthetics, durability, and heat resistance.
- Q:How are steel coils protected from condensation?
- Steel coils are protected from condensation by applying a layer of corrosion-resistant coating, such as zinc or a polymer, on the surface. This coating acts as a barrier, preventing moisture from coming into direct contact with the steel and reducing the chances of condensation occurring. Additionally, steel coils are often stored in controlled environments with controlled humidity levels to further minimize the potential for condensation.
- Q:I'm pretty sure that this topic has been beaten to death by now. But, I still can't get a definite answer. With stainless steel, you get better corrosion resistance, and you will hold and edge longer. With carbon steel, you will hold a sharper edge, and you could forge a knife blade longer than 2 ft without breakage. I'm personally a fan of stainless steel ( the 440 grade stuff ), just because it seems to hold up to use and abuse better in the long run. HOWEVER, I have NEVER had a factory made knife break on me. I don't think that they would try to sell you a knife that didn't do what it was meant to do, at least to a reasonable degree. (I work for a living, and can't afford a custom $600 knife.) What do you think? Is this a pointless topic? Will there ever be a winner?
- If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
- Q:What are the different surface treatments for steel coils?
- There are several different surface treatments available for steel coils, depending on the desired outcome and application. Some of the most common surface treatments for steel coils include: 1. Hot-dip galvanizing: This process involves immersing the steel coils in a bath of molten zinc, which forms a protective layer on the surface of the steel. Hot-dip galvanizing provides excellent corrosion resistance and is often used for outdoor applications. 2. Electro-galvanizing: Similar to hot-dip galvanizing, but instead of immersing the steel coils in molten zinc, a thin layer of zinc is electroplated onto the surface of the steel. Electro-galvanizing provides good corrosion resistance and is commonly used for indoor applications. 3. Powder coating: This process involves applying a dry powder to the surface of the steel coils, which is then heated and cured to form a hard, durable coating. Powder coating provides excellent corrosion resistance and is available in a wide range of colors and finishes. 4. Paint coating: Steel coils can also be coated with a liquid paint, which provides both corrosion resistance and aesthetic appeal. Paint coatings can be applied in various thicknesses and finishes, depending on the desired look and level of protection required. 5. Phosphating: Phosphating is a chemical treatment that involves immersing the steel coils in a phosphate solution. This process creates a thin, adherent layer of phosphate on the surface of the steel, which enhances paint adhesion and improves corrosion resistance. 6. Chromate conversion coating: Also known as chromating or passivation, this process involves immersing the steel coils in a solution containing chromium salts. Chromate conversion coatings provide excellent corrosion resistance and also act as a primer for subsequent paint or powder coating. 7. Zinc-nickel plating: This surface treatment involves electroplating a layer of zinc-nickel alloy onto the steel coils. Zinc-nickel plating provides superior corrosion resistance compared to pure zinc plating and is often used in demanding environments. These are just a few of the many surface treatments available for steel coils. The choice of treatment depends on factors such as the application, desired level of corrosion resistance, aesthetic requirements, and budget. It is important to carefully consider the specific needs of the project and consult with experts to determine the most suitable surface treatment for steel coils.
