ASTM A606 alloy weathering steel pipe is a high-strength low-alloy structural steel with excellent atmospheric corrosion resistance.

JIS G4053 SNCM 439 Seamless Steel Pipe‌ is a high-strength alloy structural steel. The implementation standard is JIS G4053-2008, and it belongs to nickel-chromium-molybdenum tempered alloy structural steel.

Stainless steel pipe is a hollow steel pipe that is not easy to rust. Non-magnetic, usually used as a conduit for conveying fluids. Stainless steel pipes can also be classified according to different manufacturing processes, including four basic types: hot-rolled stainless steel pipes, extruded stainless steel pipes, cold-drawn stainless steel pipes and cold-rolled stainless steel pipes.

This specification covers straight seam and spiral butt seam welded unannealed austenitic stainless steel tubular products intended for low and moderate temperatures and corrosive service where treatment is not necessary for corrosion resistance.
