A335 Grade P23 Pipe is a low alloy carbon steel (Cr-Mo) that is self quench in air, where the welding adquire high hardnees and residual stress not recomended to put it directly in services that demand critical conditions.

Alloy steel seamless pipes covered by ASTM A213, ASTM A335, and ASTM A519 are used in various high-temperature and high-pressure applications.

ASTM A671 GR.CC60 steel pipe is a kind of pipe used for high-pressure purposes. It is mainly manufactured by electrofusion welding process and belongs to a grade in the ASTM A671 standard.
