18CrMo4 Alloy Steel
Qilu is an 18CrMo4 alloy steel manufacturer that offers a wide selection of sizes, shapes, and thicknesses.
Professional 18CrMo4 Alloy Steel Supplier
18CrMo4 (1.7243) is an alloy structural steel with good process and welding properties. It has high enduring strength in the temperature range of 500 to 550°C. However, when the temperature exceeds 550°C, its oxidation resistance decreases, and its creep strength is significantly reduced. The thermal strength and strength of 18CrMo4 steel decrease during prolonged exposure to 500 to 550°C. This material is commonly used in the manufacture of high and medium-pressure steam conduits and header tanks at 510°C, as well as superheaters and forgings with wall temperatures of 550°C.
