Heat Treatment:

10CrMo9-10 steel plates are generally supplied in a normalized and tempered condition. Normalization is performed to refine the grain structure, and tempering is done to achieve the desired mechanical properties. The steel can also be supplied in quenched and tempered condition if required by specific applications.

Available Dimensions:

TJC Steel Group offers 10CrMo9-10 steel plates in a wide range of sizes to meet various project requirements. The typical available dimensions are:

· Thickness: 6mm - 300mm

· Width: 1500mm - 4020mm

· Length: 3000mm - 18000mm

Low-Temperature Impact Test:

The material is subjected to a low-temperature impact test at -30°C to ensure its toughness and resistance to brittle fracture at low temperatures. This is particularly important for applications where the equipment may be exposed to cold environments.

Main Applications:

10CrMo9-10 steel plates are widely used in the manufacture of industrial boilers and pressure vessels, especially in applications involving high temperatures and pressures. Some of the typical applications include:

· Steam boilers for power generation

· Pressure vessels for chemical processing
