General Information Principal Design Features One of the most widely used and oldest of the stainless steels. This was originally called 18-8 which stood for its chromium and nickel content. It possesses an excellent combination of strength, corrosion resistance and fabricability. It is available in Applications The list is endless. Almost every conceivable industry uses some of this material in some way. Everything from stovetops to ball point pen barrels to flatware to fasteners has been fabricated from this alloy. Machinability Slow speeds and heavy feeds will minimize this alloys tendency to work harden. Due to long stringy chips, the use of chip breakers is advisable. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series Corrosion Resistance Resistant to a wide range of environments between moderately reducing and slightly oxidizing. This covers food, fresh water, sterilizing solutions and dilute nitric and acetic acids. Welding All fusion and resistance processes have been successfully employed in welding 304. AWS E/ER308 or 312 filler metal is recommended. For cleaner, stronger welds, may users choose 304L which has a controlled low carbon content designed to reduce carbide pre Hot Working Forging, heading and other hot working should follow uniform heating to 2100-2300 F (1149-1260 C). Rapid cooling is necessary to attain maximum corrosion resistance in finished parts. Cold Working Readily fabricated by most cold working methods, 304 may require intermediate annealing to avoid cracking or tearing from radical deformation. Full annealing should follow any operation to reduce internal stress and optimize corrosion resistance. Annealing 1850-2050 F (1010-1121 C) followed by rapid cooling. Hardening This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength. Physical Data
