- Q: How are steel coils used in the production of steel nails?
- Steel coils are used in the production of steel nails as they serve as the primary raw material. The coils are unwound and fed into a nail-making machine, where they are cut, shaped, and formed into individual nails. This process allows for efficient and consistent nail production, ensuring high-quality and durable nails for various construction and manufacturing purposes.
- Q: 420 440 1045 or 1065 ive bought knifes with these steel grades and i want to know which one is better.
- SAE 440 is the best. Classified as high grade cutlery steel. There are various grades of 440: A, B, C, and F. 440 A is the most stain resistant while 440 C has the most carbon and can achieve the highest hardness (Best edge Retention). SAE 440 Chemistry: 16 - 18% Chromium, 0.60 - 1.2% Carbon, 0.75% Molybdenum. SAE 420 is pretty good. Classified as cutlery steel, it is a stain resistant grade but has less chromium and significantly less carbon than SAE 440. SAE 420 Chemistry: 12 - 14% Chromium, 0.15% Carbon (min), 0 Molybdenum Chromium is what makes the steel corrosion resistant. It also adds toughness. Molybdenum adds extra corrosion resistance and adds hardenability. So you can see by chemical components that 440 is highest quality although that also means more cost. 1045 and 1065 are low quality steels and you should probably never use them for a knife. The 1 indicates plain carbon steel with little other alloying elements. The last two digits indicate how much carbon is in the steel. 1045 has 0.45% carbon, mid-range hardenability. 1065 has 0.65% carbon, high hardenability. So if I had to choose I would choose 1065 over 1045 but the difference isn't that noticeable. Everything I said here assumes they have all had the optimum Quench and Temper heat-treatment for their chemistry grade.
- Q: What are the different methods of recoiling steel coils?
- There are several methods used for recoiling steel coils, depending on the specific requirements and characteristics of the material. Some of the common methods include: 1. Slitting: This method involves cutting the steel coil into narrower strips, which can then be recoiled. Slitting is typically done using rotary knives or circular saws, and it allows for precise width control. 2. Rewinding: This method involves unwinding the steel coil and then rewinding it onto a new coil mandrel. It is commonly used when the original coil needs to be resized, or when the coil has become damaged and needs to be reconditioned. 3. Recoiling with a tension control system: In this method, the steel coil is passed through a set of tension control rollers, which apply a controlled amount of tension to the material. This allows for a smooth and even recoiling process, minimizing the risk of coil distortion or damage. 4. Recoiling with a slitter head: This method combines the slitting and recoiling processes into a single operation. A slitter head is used to simultaneously cut the steel coil into narrower strips and rewind them onto separate coils. 5. Recoiling with a looping pit: In this method, the steel coil is fed through a looping pit, which allows for the accumulation of material as the coil is recoiled. This helps to maintain a consistent line speed and tension during the recoiling process. Each of these methods has its own advantages and is suitable for different applications. The choice of recoiling method depends on factors such as the desired coil dimensions, the material's thickness and strength, and the required level of precision and quality.
- Q: I am using mild steel wire (very thin and bendable) for an art project, and would like to know if using a soldering torch is effective enough to get the job done. Or do I have to use a butane torch to heat the metal?BTW, is it better to use soft or hard solder?
- You can indeed by using the correct flux as normal soldering fluxes as used by plumbers will not work. I believe to solder steel it requires an acid flux which will corrode copper so when its done make sure its well cleaned afterwards and if possible apply a corrosion proofer afterwards ie paint or even petroleum jelly. I am curious as to why you would want to solder wire to a steel nail.
- Q: How is the thickness of a steel coil measured?
- The thickness of a steel coil is typically measured using a gauge, which is a specialized tool specifically designed for measuring the thickness of materials. The gauge is pressed against the coil, and the reading on the gauge indicates the thickness of the steel.
- Q: Steel seems to be much less expensive. What is the reason why? I've heard steel will ruin a barrel after time....is that true? But with the price difference maybe it don't matter? Is steel reliable? What are the negatives about steel I should know before buying?
- Steel is a cheaper material than brass. Simple as that. Steel is harder than brass as well so it can cause wear on the chamber and bolt at a faster rate. What some places do it's not pure steel but they mix in other softer metals to make the casing softer so it's not as much as issue as people make it out to be. People tend to dislike steel cased ammo as well due to it running dirtier and the coating on the casing gumming up the insides. But these people from my experience do not clean their guns. Ever. And then when they start to act up they wonder why.
- Q: ive made lots of knives but they are dark and not shiny. how do i polish a knife and make it shiny
- Look for buffing compound at the hardware store. Home depot lowe's od even Wal-mart/ There is a compound for steel and for iron. I t will not make iron real shinny but it will make it look good. This stuff is to be used with a buffing wheel but I have used it on rags and it work great.
- Q: This question gets beat to death from what ive seen online but im going to ask it since im searching for a few new knives. The question is as the titles states what is the best steel for a general purpose knife? I plan on buying several different types of knives, Folders, fixed blades, ect. I will carry them around with me all the time for basically anything i can think of to use it for. The reason i ask this question here is because looking online everyone has a differnt veiw. Some say stainless is too soft while others say carbon will chip and is more brittle. Even looking at just a single type of steel, carbon fort instance everyone has a different opinion as to whats best leaving me kind of lost for what i should get. Maybe the better word would be What is a good general purpose steel?. Any advice is much appreciated!!!!
- Besides the composition of the steel, the tempering is VERY important. I would buy a knife from a company with a good reputation and not worry about what material their metallurgist chose to make a high quality knife. You definitely do not have the knowledge of someone with a degree in metals and many years of experience.
- Q: Which one is stronger steel or metal ( for bow and arrows) please answer I need it for a book I'm writing
- Metal includes steel, as well as thousands of other metals and alloys. In other words, steel IS a metal. So your question is meaningless, sorry.
- Q: How are steel coils inspected for quality control purposes?
- Steel coils are inspected for quality control purposes through various methods such as visual inspection, dimensional checks, and non-destructive testing techniques. Visual inspection involves examining the surface of the coil for any defects or irregularities. Dimensional checks are conducted to ensure that the coil meets the specified thickness, width, and length requirements. Non-destructive testing techniques like ultrasonic testing or magnetic particle inspection are used to detect internal flaws or defects in the steel coil. These inspection methods help ensure that the steel coils meet the desired quality standards before they are used in various applications.
