15CrMo, also known as heat-resistant steel, is a type of alloy structural steel mainly composed of Cr and Mo. 15 represents a carbon content of 0.15%, Cr represents the added chemical element "complex", and Mo represents the added chemical element "molybdenum"
15CrMo is an alloy structural steel plate mainly composed of nickel, copper, and molybdenum. 15CrMo has good processability and welding performance, and has high tensile strength, thermal strength, and oxidation resistance at 500 to 550 ℃. The execution standard for 15CrMo is GB/T 3077-2015 Steel Plate Standard GB/T11251-2009.

15CrMo Alloy Steel Plate Condition
The delivery status is generally hot-rolled, and the delivery status should be specified in the contract between both parties.
Application Area of 15CrMo Alloy Steel Plate
15CrMo is widely used worldwide, adding core chemical elements such as Cr and Mo to low-carbon materials, greatly improving its overall performance. It has excellent high-temperature performance, high-temperature oxidation resistance, corrosion resistance, and toughness. Widely used in the manufacturing of large-scale equipment with harsh operating conditions and complex corrosive media, such as petrochemical, coal conversion, nuclear power, steam turbines, cylinder bodies, thermal power, etc.
Direct visual inspection of the surface quality of steel plates and strips, and no defects such as cracks, bubbles, scars, folds, or inclusions that are harmful to use are allowed on the surface of the steel plates. There should be no layering on the side of the steel plate. The density of the calculated theoretical weight of the steel plate is 7.85 g/cm3, and the container plate needs to be added with an additional value. Its 15CrMo melting point is 1420-1460 ℃
