A335 Grade P21 Seamless Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding acquire high hardness and residual stress not recommended to put it directly in services that demand critical conditions. Such situation requires apply POSTWELD HEAT TREATMENT (PWHT). If you want to avoid PWHT then you can use preheat(120deg Celsius) while welding A335 Grade P21 seamless Pipe. PWHT is required if the thickness of ASTM A335/ASME SA335 P21 Alloy Steel Pipe is greater than 13 mm.
