UNS S38815 Stainless Steel Pipe And Tube is a special alloy, which is usually manufactured by AOD/VOD/VIM process, and electroslag remelting (ESR)/VAR treatment may be required according to special needs. Bars and forgings are usually ultrasonically tested according to the needs of buyers, and the inspection level varies according to the requirements of buyers.

UNS S38815 stainless steel is widely used in many industrial fields due to its unique chemical composition and material properties. It not only has excellent corrosion resistance, but also can meet the needs of high temperature and high pressure environments.

Carbon (C) content ≤ 0.030%, silicon (Si) content 5.50% - 6.50%, manganese (Mn) content ≤ 2.00%, phosphorus (P) content ≤ 0.040%, sulfur (S) content ≤ 0.020%, chromium (Cr) content 13.0% - 15.0%, nickel (Ni) content 15.0% - 17.0%, molybdenum (Mo) content 0.75% - 1.50%, copper (Cu) content 0.75% - 1.50%, aluminum (Al) content ≤ 0.30%.

Usually implements ASTM A240/A240M - 2018 "Technical Specifications for Chromium and Chromium-Nickel Stainless Steel Plates, Sheets, and Strips for Pressure Vessels and General Purposes" and other relevant standards.

Widely used in high-temperature equipment and pipelines in chemical, petroleum, natural gas, thermal power generation, nuclear power and other industries, such as for the manufacture of heat exchangers, kilns, stack dampers, oven parts, burners, boiler nozzles, petrochemical and refinery pipe hangers, expansion bellows, etc.
