As per ASME B 31.1 for ASTM A335 P36 and ASTM A182 F36 materials, post weld heat treatment is mandatory under all conditions. For class 1 material the recommended range is 595 – 650°C and for class 2 components recommended range is 540 – 620°C.

How do you treat A36 steel?As such, direct heat treating is not applicable. Case hardening is the process for treating A36 steel. Place the fire bricks around the fireproof table inside the brazing hearth, make sure that your brazing hearth and gas-air torch are in good condition and fill a large container with cold water and another with Kasenit or your chosen brand.See all results for this question

What is post weld heat treatment?

Post weld heat treatment is the most widely used forms of stress relieving on completion of fabrication of welded structures. The principle is that as the temperature is raised, the yield stresses and the elastic modulus of the material fall.See all results for this questionWhat is ASTM A36 steel used for?ASTM A36 steel has the following applications: It is used in bolted, riveted or welded construction of bridges, buildings and oil rigs.See all results for this questionWelding heat treatable steels - The FabricatorThe heat treatment produces a desired microstructure that changes the mechanical properties of the material to a desired strength and ductility level. Do not confuse a heat treatment with postweld stress relief. The postweld stress relief is exactly thata method to relieve stresses that are the direct result of the welding process.
