AISI 304 and 304L (SS304L) are austenitic stainless steels, and also known as 18/8 stainless steel. Stainless steel, a rust-resistant variation of ordinary steel, comes in many standard types, each identified by a number. Cold Rolled, Annealed No. This alloy was first developed by Firth Brown Steels nearly a century ago. I constantly use aluminum, stainless steel and other specialty metals in the form of rails, sheets, beams, etc. It has the chromium and nickel content of 18-8 stainless steel but contains a maximum of 0.08% carbon as well. It can withstand corrosion that can be caused by various chemicals found in fruits, meat, and milk. Martensitic . This makes it much more resistant to rust. AKA just “stainless”, stainless steel is steel that has been alloyed to maximize it’s corrosion resistance. This grade has slightly lower mechanical properties than the standard 304 grade, but is still widely used thanks to its versatility. This makes it much more resistant to rust. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. 304 Stainless Steel Pipe. The “L” in 304L can be interpreted as meaning extra-low carbon. Oven stress-relief temperature and time for 304 stainless steel wire: 345 °C (650 °F), minimum 30 minutes. The two steel grades are comparable in appearance, chemical makeup and characteristics. 303 vs 304 vs 316 Stainless Steel. Grade 304 is the standard "18/8" stainless that you will probably see in your pans and cookery tools. It is also known as "18/8" stainless steel because of its composition, which includes 18% chromium and 8% nickel. Type 304 is the most versatile and widely used stainless steel.
