Q:Does anyone know how to make a steel helmet, or does anyone know where to direct me websites-wise? i've just started looking on the web for info, so when i get back here i might've already found some info, but more wouldn't hurt, especially if from people who are interested on the subject. i know nothing about metallurgy, nothing on the art of metal working etc... please help.: The okorder (Artist Blacksmiths) or on the sites of the two organizations that reproduce old costumes and tools - one is called The Society for Creative Anachronism, not sure of the other. Search terms to use might be hammering a helmet and forging medieval armor

Q:What are the different methods of skin pass rolling for steel coils?: There are several methods of skin pass rolling for steel coils, including dry skin pass, wet skin pass, and temper rolling. Dry skin pass involves using a roller with a specific surface texture to improve the appearance and flatness of the steel coil. Wet skin pass, on the other hand, involves applying a thin layer of oil or water during the rolling process to enhance the surface finish and prevent oxidation. Temper rolling is a method used to improve the mechanical properties of the steel coil by subjecting it to a controlled amount of cold deformation. Each method is employed based on the desired outcome and specific requirements of the steel product.

Q:How are steel coils used in the production of shelving units?: Steel coils are used in the production of shelving units by being cut and formed into various components, such as brackets and supports. These components are then assembled and welded together to create the frame and structure of the shelving unit. The steel coils provide strength and durability to the shelving units, ensuring they can withstand heavy loads and provide long-lasting storage solutions.

Q:So I'm looking for some decently priced black motorcycle boots that have steel toes (and any additional protection) and look good in jeans. Pretty simple. Any recommendations?: you can go for UDYOGI make safety shoe.

Q:density of mild steel (MS) is 7850 KG per metre cube , but i want to know the density of stainless steel: Stainless Steel Density

Q:I need a machine which can produce steel pipes, but I don't know where to look...If you want me to state dimensions etc. just say...Thanks :): Gary, Indiana. There's lots of old, unused steel forming equipment just laying around.

Q:For the purpose of blade crafting. I need to heat treat this low quality steel i got.It's ASTM A36Is heat treatable and temperable?: A36 is plain carbon structural steel. A36 could almost be considered junk steel. It is not suitable for cutting tools in any respect, as it is far to soft to hold an edge. A36 generally cannot be heat-treated, A36 can only be strengthened by cold-working, and even then, only up to about 60,000 psi. Heating the steel will only make it softer. The only real virtue of A36 is that it's easy to work with, it's easily cut and machined and it is very easy to weld. This is good for making steel structure, but not for knives. Probably the most popular material for knife blades is type 440C stainless. 440C is easy to work with in the un-treated state, and the heat treatment procedure is relatively simple.

Q:All the steel straps that secure my deck and stair 6x6 posts to the concrete piers have some rust on them. Had bought a rust reducer to spray on them and repaint. As I went to do this I found that one of them is on its last legs, with the steel rusted through and bubbling up all up the sides of the straps. Since this is the end post on a row of 3 deck support posts, I was thinking of removing as much rust as possible, then paint with Rustoleum and cover lower post with something to keep water away from post and pier in the future? Was thinking of something removeable so I could check on it for further rusting. What do you folks with building experience think of this? Thanks.: If these steel straps are rusting through and on their last legs, a coat of paint is going to be cosmetic at best. Replace these straps with new ones. The originals were either very poorly galvanized, or you live someplace with a very corrosive environment. In any event, paint can't save this sort of thing. Steel brackets serve a real purpose, and after they're weakened, they can't do that anymore. How would your home hold up in an earthquake, for example? What you're proposing doesn't sound safe.

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 is the shelf life of a steel coil?: The shelf life of a steel coil can vary depending on various factors such as the type of steel, storage conditions, and specific industry requirements. However, in general, if properly stored and protected from moisture, corrosion, and other damaging factors, a steel coil can have a shelf life of several years.
