Stress Relieving Heat Treatment for Austenitic Stainless Steel
Stress Relieving Heat Treatment for Austenitic Stainless Steel. Unlike martensitic stainless steel, the austenitic stainless steel are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 1120C range, ideally followed by rapid cooling.Stress Relief of Austenitic Stainless SteelsJan 05, 2011 · Grades such as 304 or 316 are, therefore, processing in the temperature range of 900-1600ºF (480-870ºC) should be avoided. Slow cooling through this range can also be problematic. 2. A full solution-anneal stress-relief heat treatment will retransform any martensite formed back to austenite.Stainless Steel | Vested Metals316 is one of the most common austenitic stainless steels. 316 contains a controlled amount of chromium, nickel, and molybdenum, which helps increase corrosion resistance. The high corrosion resistance makes the 316 a widely used steel in marine applications.
