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

A335 Grade P5b 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.

EN S235JRH structural square tubes are commonly used in buildings, bridges, towers, support structures, mechanical equipment and other fields.

ASTM A210 A1 seamless boiler tubes are mainly used to manufacture headers, main steam pipes, etc. for the heating surface of high-pressure boilers, and are power station boilers and superheaters.
