316L Stainless Steel Data
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.
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. To Anneal, 1850-2050 F (1010-1121 C), followed by rapid cooling.
