DIN17175 13CrMo44 seamless steel pipes description
The 13CrMo44 alloy tube is primarily used for heating surface piping in low-to-medium pressure boilers, with operating pressures typically not exceeding 5.88 MPa and temperature applications below 450°C. This tube material can be employed to manufacture boiler components such as superheater tubes, boiling water tubes, and water-cooled wall tubes. It is also suitable for high-pressure boiler systems operating above 9.8 MPa, producing components like economizers, superheaters, and reheaters, and is applicable for tubes in the petrochemical industry.
Its chemical composition includes elements such as carbon (C), silicon (Si), manganese (Mn), and phosphorus (P). The outer diameter specifications range from 8 to 1240 mm, with wall thicknesses varying from 1 to 200 mm.
