Quenching Improve the hardness of A709 Gr 50W carbon steel plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A709 Gr 50W carbon steel plate steel and comprehensive mechanical properties.
We are world class steel materials supplier and exporter. Our main steel materials are: carbon and hsla steel, boiler and pressure vessel steel, gas cylinder steel, shipbuilding and offshore platform steel, pipeline steel, weathering steel / corten steel, A709 Gr 50W carbon steel plate alloy steel, automobile structure steel, abrasion resistant steel, clad steel, stainless steel etc.. Meanwhile, we also have steel processing center, and can provide cutting, welding, bending, drilling etc. processing for steel materials.
Through chemical composition analysis and simulation tests, it is found that A514 Gr Q steel plate is prone to cracks or decreased toughness during welding. ASTM A514 Gr Q steel plate is sensitive to cold cracking. In order to obtain good weld quality of A709 Gr 50W carbon steel plate, A514 Gr Q steel plate, it should be controlled from two aspects: (1) control the hardness value of HAZ; (2) control the residual diffusible hydrogen content.
The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.
