A335 P9 seamless pipe is a high performance alloy steel pipe, mainly used in high temperature and high pressure environment.

EN 10305-1 C35E grade pipe is ductile and strong with long-term wear characteristics. These tubes are manufactured to EN specifications and are commercially known as carbon steel tubes.

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.

ASTM A213 Stainless Steel 304H Boiler Tubes has general corrosion resistance similar to the low carbon 304/304L.
