Stainless Steel 304, like 302, has good mechanical properties and corrosion resistance. Stainless Steel 304 is also known as AISI 304.
Type 304/304L is the modern version of “18-8” stainless steel containing approximately 18% chromium and 8% nickel and is the most commonly specified stainless steel used throughout the world. Type 304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, and to many chemicals and food and beverages.
304 stainless steel strip and slit to width coil, ASTMA-666, is similar to Type 302, but has a maximum carbon content of 0.08%. This material has an excellent combination of corrosion resistance and formability. 304 is also known as 18/8 chrome-nickel, austenitic, stainless strip.
A. 304 is an austenitic stainless steel. You can't through-harden it. You might be able to nitride it, but this will probably create more problems than it is worth; nitriding would reduce the corrosion resistance. Type 302 / 304 is used in many applications including laser welded tubing, bellows, laser and chemical etching, medical, food and tool wrap applications. Type 302 / 304 is dual certified to meet both the 302 and 304 alloys. It is available in COIL and SHEET at Sidecuts.com®.
