A213 T11 Boiler Tube

GNEE is the main supplier of A213 T11 seamless steel pipes, we provide high quality steel pipes to customers all over the world according to their needs.
The added elements of A213 T11 alloy pipe are carbon, silicon, manganese, nickel, phosphorus, chromium, sulfur, molybdenum, etc. Its minimum tensile strength is 415MPa and the minimum yield strength is 205MPa.
Because of the addition of 0.5% carbon and 1% chromium, A213 T11 seamless alloy pipe has the advantages of corrosion resistance, oxidation resistance, and high temperature resistance.
A213 T11 boiler tube is similar in strength to 304 and 316 stainless steel, but has greater heat resistance and hardness. Therefore, A213 T11 high-temperature steel pipes are used in heating and piping systems that transport gases and liquids.
