Specification
Hot Rolled Steel A rolling process at temperatures over 1,000 degrees Fahrenheit is use to create
hot rolled steel. Steel products in Massachusetts that have been processed in this manner will have a
blue-gray finish that feels rough to the touch.
Hot rolled steel actually reconfigures itself during the cooling process, giving the finished product
looser tolerances than the original material and when compared to cold rolled steel products.
Hot rolled steel is more malleable, allowing it to be forced into a variety of different shapes.

- Q: I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?
- No. People who say that don't use steel cased ammo. It it said its harder on the extractor. I don't see how. Its dirtier because it doesn't expand like brass does but the steel casing is still softer than the steel of the gun. That is a mild steel which isn't as hard as what most people are thinking of.
- Q: What are the environmental benefits of using steel coils?
- Using steel coils offers several environmental advantages. To begin with, steel is a highly recyclable material. Steel coils can be easily recycled and transformed into new steel products, reducing the necessity for mining and extracting raw materials.

- Q: What are the common coil finishes available for steel coils?
- Steel coils can be finished in various ways to serve different purposes and achieve different aesthetic appearances. Some popular coil finishes include: 1. Hot-dip galvanized: By immersing the steel coil in molten zinc, a protective layer is formed on its surface. This finish is ideal for outdoor applications like roofing, fencing, and automotive parts due to its excellent corrosion resistance. 2. Galvannealed: Achieved by annealing the hot-dip galvanized coil, this finish gives a matte gray appearance. Galvannealed coils have enhanced paint adhesion, making them suitable for subsequent painting or powder coating in applications like appliances and furniture. 3. Electro-galvanized: A thin layer of zinc is electroplated onto the surface of the steel coil in this process. Electro-galvanized finishes offer good corrosion resistance and are commonly used indoors, such as in electrical enclosures, HVAC systems, and automotive components. 4. Pre-painted or coated: These finishes involve applying a layer of paint or a coating system to the steel coil, improving its appearance and providing extra protection. Pre-painted coils are extensively used in construction, appliances, and automotive industries due to their aesthetic appeal and corrosion resistance. 5. Bare or mill finish: This refers to the untreated, raw steel coil without any additional coatings or finishes. Bare steel coils are commonly used in applications where corrosion resistance is not the main concern, such as structural components, pipes, and tubes. These are just a few examples of the many coil finishes available for steel coils, each offering unique properties and advantages depending on the intended use. Carefully considering the specific requirements of the application is important when choosing the most suitable coil finish.

- Q: I am searching for an online article which discusses any aspect of the use of austenitic stainless steels. I was just wondering if anyone could help me find one. No sales articles. Thank you!
- *Austenitic, okorder
- Q: We have to do a project for school on steel mines and i need 4 PROPERTIES OF A STEEL MINE PLEASE HELP!!! URGENT!!!
- The existence of them would be a good start. Steel is produced from iron ore, not mined.
- Q: I just bought a dpms ar15 and it says if I shoot steel cases (laquer coated) or foreign ammo it voids the warranty. But before I knew this I bought 200 rounds of Russian steel cased anmo. Think I should just shoot there two hundred and not buy anymore? Some people say all they shoot is steel cased ammo and have no problemAny advice is appreciated
- I am not aware of any catastrophic failures being attributed to Russian Steel cased ammo use. I would recommend checking out the several AR15 message boards and see what everyone who uses it has to say and if anyone has had serious problems. I have personally used Wolf steel case in all of my ARs with no serious issues. I have also fired it in several full auto rifles. What I noticed is that it is dirtier ammo than Winchester or Federal ammunition and I will get an occasional failure to eject. Right now, American production brass cased .223 is $.50-$1.00 or more per round when you can find it.. The Russian Wolf can be found for $.40 or less. Most people shoot whatever they can find and afford and do not worry about the warranty.
