ASTM A847 weathering steel pipe is a cold-formed welded and seamless high-strength, low-alloy round, square, rectangular or special-shaped structural pipe.

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.

Stainless Steel 310H (UNS S31009) is a higher carbon version of 310 Stainless Steel which has a higher carbon content than 310 and is typically used in environments where thermal cycling and resistance to high temperature corrosive conditions is critical.

SUS630 also known as 17-4PH, is a high-strength, corrosion-resistant martensitic stainless steel alloy.
