34CrMo4 steel and 20MnB5 alloy steel for general structural purpose

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.

Boiler steel plates for room temperature and medium temperature (below creep temperature) are mostly carbon steel, including carbon steel, carbon manganese steel, carbon manganese silicon steel, 34CrMo4 steel and 20MnB5 alloy steel, etc. They are mainly used in the manufacture of pressure-bearing parts such as boiler drums and header end covers below medium temperature. High temperature (above creep temperature) boiler steel plates are mainly used to manufacture high-temperature pressure-bearing parts such as high-temperature header end caps and steam pipe blocking plates.

34CrMo4 steel and 20MnB5 alloy steel, API 5L X52 steel with the thickness range is 1.2-40mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. API 5L X52 steel’s mechanical properties is the yield strength 300MPa, and the tensile strength 460MPa. To be specified in details: Maximum content for C≤0.28%, Mn≤1.4%, P≤0.030%, S is 0.030%, V+Nb+Ti≤0.15%, Copper maximum is 0.50%, nickel maximum 0.50%, chromium 0.50%, Molybdenum 0.15%.
