S690QL1 ASTM equivalent surface treatment

Shipbuilding steel plates are used to manufacture marine and inland ship hulls, which require high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. BBN steel company produces various grades steel plates for shipbuilding like AH32, AH36, AH40, DH32, DH36, EH32, EH36, S690QL1 ASTM equivalent and can produce marine steel plates and sheets with different certificates according to client needs.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S690QL1 ASTM equivalent quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After S690QL1 ASTM equivalent quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.
