Answer / Kiran Kuma

The minimum temperature for stress relieving ASTM A 519 Gr.4130 material typically ranges between 600-700°F (315-371°C) and is dependent on the specific heat treatment process used. The exact temperature can be found in the Heat Treatment section of the ASTM A 519 standard, which provides guidelines for the processing and heat treatment of chromium-molybdenum steels. It's essential to follow these guidelines for proper stress relief annealing.
