Principal Design Features 316L is often substituted for 316 stainless due to its superior weldability with no appreciable difference in price or properties. It combines good availability in all forms and size ranges with great strength and corrosion resistance.
Applications Components used in marine environments and chemical equipment. Suitable for any application where 316 stainless is used and stronger welds are desirable.
Machinability Low speeds and constant feeds will minimize this alloy’s tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series.
Welding All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 316L filler metal for best results.
Hot Working All common hot working processes are possible with this alloy. Heat to 2100-2300 F (1149-1260 C). Avoid working this material below 1700 F (927 C). For optimum corrosion resistance, a post-work annealing is recommended.
Cold Working Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.
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.
