UNS S38815 Stainless Steel Pipe and Tube

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%.

Excellent high temperature performance: UNS S38815 Stainless Steel Pipe And Tube can maintain high strength and stability at high temperatures, can be used stably for a long time, and is suitable for equipment and pipelines in high temperature environments.

Good corrosion resistance: It has good resistance to corrosive media such as acids, alkalis, and salts.

High strength: The strength is 30 - 50% higher than that of general stainless steel, and it has good tensile and compression resistance.

Good machinability: It has good machinability and weldability, and conventional machining and welding methods can be used.

Good oxidation resistance: It also has excellent oxidation resistance in high temperature air.

Low thermal expansion coefficient: The thermal expansion coefficient is lower than that of general stainless steel, making it more stable at high temperatures.

Low carbon content: It is more stable at high temperatures and is not easy to produce carbides.

Usually implement 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.
