WELDING CHARACTERISTICS: This alloy is suitable for welding. All the standard fusion methods can be used, for its welding, and there is no heat treatment required later. However, the oxyacetylene process does not apply to this alloy.The welding can be done, with filler metals with molybdenum content higher than the base metal or even without any filler metals. 316 L does not require post-weld annealing. However, some of the heavy weld sections of Grade 316 require post-weld annealing. It is, usually done to maximise corrosion resistance.
STAINLESS STEEL 316 HEAT TREATMENT: The internal stresses in the alloy are removed, in the process of annealing. Stainless steel 316 should be heated, at a temperature of 1900°F. It is then cooled rapidly with the water being, quenched. However, type 316/316L cannot be hardened through heat treatment.
