304L material
Design Features:A low carbon version of type 304 stainless.304L is used almost interchangeably with 304 but is preferred for welding operations.It offers a good combination of strength,corrosion resistance and fabricability.
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.
