Weather-resistant ASTM A423 Grade 1 steel pipe, suitable for pressure-containing components such as economizers or other applications requiring corrosion resistance.

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.

ASTM A335 P11 P12 P22 steel pipe is a low carbon steel with specific chemical composition and mechanical property requirements, and its hardness and strength can be improved through different heat treatment methods.

ASTM A335 P11 Pipe (ASME SA335 P11) is Chrome Moly Alloy Seamless Pipe that used for high-temperature services, P11 Grade Pipe Chrome content at 1.00% to 1.50%, Moly content 0.44% to 0.65%, Minimum tensile strength 415MPa, minimum yield strength 205Mpa.
