Q:is stainless steel a good steel for sensitive skin? or does it have to be surgical or sterling silver?: Surgical stainless steel 316LVM is good, 316L is nowhere near in quality. Its very unusual for someone to have a reaction to surgical steel. Avoid plain stainless steel. Titanium is better, tougher and lighter. And contains less nickel than surgical steel, pretty close to nothing. Its pretty much impossible to be allergic to good quality titanium. Niobium contains no nickel, but only comes as CBRs, and is pretty expensive and unusual. Silver and gold should be avoid in piercings. They have to mix it with so much other junk so that its strong enough, really high nickel content.

Q:What is the size range of steel coils?: The size range of steel coils can vary depending on the specific requirements and applications, but generally, they can range from a few inches to several feet in width and from a few thousand pounds to several tons in weight.

Q:I've heard on some 1911 forums that the slides of Armscor guns are now extruded. What is extruded steel? How is it made? Are they strong (4140carbon steel was used in the process).: Extruded steel is only the steel being run through a die when it is heated, it usually reduces the size of the grain of the steel itself, enhancing toughness. Realistically though, in a handgun, it doesn't matter if the frame is cast or forged, both types will hold up to any amount of abuse, unless you use it as a sledgehammer, and are splitting stones with it, then the forged frame would win. 4140 is more than adequate for a slide/frame. Hell, even mild steel would be adequate as long as you don't mind some dings and scratches, and again, don't use it as a sledgehammer...

Q:How are steel coils processed before they are used in manufacturing?: Steel coils undergo several processing steps before they are used in manufacturing. The first step is called pickling, where the coils are immersed in an acid bath to remove any surface impurities, such as rust or scale. This helps to improve the surface quality of the steel. After pickling, the coils go through a process called cold rolling. This involves passing the coils through a series of rollers to reduce their thickness and improve their dimensional accuracy. Cold rolling also enhances the mechanical properties of the steel, making it stronger and more durable. Next, the coils are annealed, which involves heating them to a specific temperature and then slowly cooling them. Annealing helps to relieve internal stresses in the steel and improves its formability and ductility. Following the annealing process, the coils may undergo additional surface treatments, such as galvanizing or coating. Galvanizing involves applying a layer of zinc to protect the steel from corrosion, while coating can involve applying various types of paint or polymer to enhance the steel's appearance or provide specific functionalities. Once the coils have been processed and treated, they are typically cut into smaller sheets or strips, depending on the manufacturing requirements. These sheets or strips can then be used in various manufacturing processes, such as stamping, forming, welding, or fabrication, to create a wide range of products, including automotive components, appliances, construction materials, and many others. In conclusion, steel coils undergo a series of processing steps, including pickling, cold rolling, annealing, and surface treatments, before they are ready to be used in manufacturing. These processes improve the quality, strength, and formability of the steel, allowing it to be transformed into a variety of products.

Q:What is the lifespan of a steel coil?: The lifespan of a steel coil can vary depending on various factors such as the quality of the steel, the conditions it is exposed to, and how well it is maintained. However, on average, steel coils can last anywhere from 10 to 30 years.

Q:What is the difference between cold rolled strip and cold rolled steel coil?: A simple point is the difference between a strip and a volume. Strip is the flat strip of cold rolling, which is further processed on the basis of flat strip and rolled into thinner and can be rolled up,

Q:hi i was doing a little history project on guns. i was just wondering if anyone could help me find out what material was used before steel and why this material wasnt as good as steel ( its faults)thanks for your help: The most common was bronze, which was the strongest material that could be cast, at least until the industrial revolution. Until that time, furnaces which could reach temperatures hot enough to melt steel did not exist. The only way to work with steel would have been forging, which means hammering it into shape while red-rot. Obviously, this is not a very practical method for making large thick-walled cannons (though it was done on occasion. Small arms such as pistols and muskets could be easily made of steel by hand forging.) The most practical way to make cannons was pouring molten bronze which melts at significantly lower temperature than steel. Cast iron was also used. Note that Cast Iron contains 3%-7% carbon, compared to steel which only contains between 2% to 0.2% carbon. Due to the excessive carbon content of cast iron, it's melting point is about 500 degrees lower than steel enabling it to be melted with pre-industrial furnaces. Unfortunately, cast iron is also brittle, unlike steel or bronze. This means that a defective or cracked casting could easily explode, sending iron shrapnel everywhere. (Also, maiming and killing the gun crew, an experienced gun crew was as valuable as the cannon itself!) For this reason. Cast iron cannon were usually considered a cheap, risky alternative to expensive but durable bronze.

Q:Hi can someone help me pleaseis there any available data for mechanical behaviour of recycled steel, i need to compare them with new steel.: Most recycled steel is blended with new steel at the steel mill. Scrap steel that is reused directly doesn't change it properties because it has been used. That is unless it has been in certain environments such as ones with hydrogen, hydrogen sulfide etc. Then the steel can become brittle. You might look for information on the National Association of Corrosion Engineers (NACE). They have lots of information on metals and what causes problems.

Q:What is the difference between regular steel stainless steel? Why does steel rust but stainless wont? Is stainless some kind of alloy or something? Any knowledgeable input would be great. Thanx!: the reagent of choice is toluene-3,4-dithiol.

Q:How are steel coils used in the manufacturing of storage tanks?: Steel coils are used in the manufacturing of storage tanks as they provide the necessary strength and durability required for storing various substances. These coils are formed into cylindrical shapes and welded together to create the tank's body. The steel coils are also coated with protective layers to prevent corrosion and ensure the longevity of the tank.
