Annealing these stainless steels softens them, adds ductility and imparts improved corrosion resistance. 300-series stainless steels are the most popular examples of this type. Any type of warping or bending will almost instantly move the annealing into etching zone. The process involves heating the steel to a temperature above its critical point, and then cooling it rapidly. Also, I am assuming that you are using the low carbon grade of 316SS; therefore, solution annealing after welding should not be necessary (it is also not practical). Used for parts that are extensively machined and require the corrosion resistance of a 13% chromium stainless steel.

It has the second lowest strength and second highest ductility compared to the other variants of AISI 316 stainless steel. Generally, the term solution annealing is interchangeable with "solution treatment" or "annealing" in stainless steel, nickel and titanium alloy industry. Type 316 grade stainless steel is particularly effective in acidic environments. The protective atmosphere may be pure hydrogen, dissociated ammonia, or sometimes vacuum. Generally, this grade is dual-certified to meet both 316 and 316L. Price:: From $95.00 to $220.00. Effect of residual stresses Recommendations. Annealing of stainless steels is carried out at temperatures greater than 1040C, but certain types of steel can be annealed at very controlled temperatures of below 1010C while considering fine grain size. Because 316L contains less carbon, it is more corrosion resistant than 316. Alloy 316/316L (UNS S31600/S31603) is a chromium-nickelmolybdenum austenitic stainless steel developed to provide improved corrosion resistance to Alloy 304/304L in moderately corrosive environments.
