Alloy 347 stainless steel plate resists polythionic acid stress corrosion cracking in hydrocarbon service.See all results for this questionWhat is alloy sensitization? - Rolled Alloys, Inc.Several methods have been used to control or minimize the intergranular corrosion of susceptible alloys, particularly of the austenitic stainless steels. High-temperature solution heat treatment, commonly called solution-annealing, has been used. The alloy is heated to a temperature of about 1950° to 2050°F and then water or air cooled.Welding of Austenitic Stainless Steel - Part 2 - TWICarbides present in the HAZ of an austenitic stainless steel dissolve on heating and reform on cooling during the welding heat cycle. Unfortunately, these new precipitates form preferentially as chromium carbides on the grain boundaries, depleting chromium from the region immediately adjacent to the boundary, resulting in a local loss of stainless steel 347 sheet Heat treatment
Type 347 stainless steel cannot be hardened by heat treatment, in fact the only heat treat operation that is performed on it is that of annealing, at around 1950ºF (1065ºC,) followed by a water quench. This treatment gives maximum corrosion resistance for type 347 forgings.
What's the difference between 347 and 347 stainless steel?
Like most other austenitic stainless steels, type 347 work hardens and may require annealing after severe forming. Type 347 is non hardenable by heat treatment. It can only be hardened by cold working. Type 34 7 is weldable by common fusion and resistance methods.See all results for this questionTechnical Data BLUE SHEET - METSERVE347 and Type 348 stainless steels to sensitization and intergranular corrosion is illustrated by data for the Type 321 alloy in the Copper-Copper Sulfate 16% Sulfuric Acid Test (ASTM A262, Practice E) below.

Unlike martensiticstainless steel, the austeniticstainless steel are not hardenable by heat treatmentas no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 1120C range, ideally followed by rapid cooling. This is of course the complete opposite to martensitic steel, where this sort of treatment would harden the steel.
