304 material
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 the widest variety of forms and sizes for any stainless steel.

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.

Machinabilty: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.

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 interal 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.
