S960QL grade is a European standard special alloy structural steel, which belongs to quenched and tempered high yield strength structural steel. S indicates structural steel, 960 is a yield value, in MPa, Q indicates delivery conditions, and L indicates that the impact energy is specified when the temperature is not less than -50℃ The smaller value of. S960QL steel plate is a material in the European standard EN 10025-6.
The company specializes in the research and development, production and sales of A514 Gr J alloy steel plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A514 Gr J alloy steel plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A514 Gr J alloy steel plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.
How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, A514 Gr J alloy steel plate, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
The effect of alloy elements of A514 Gr J alloy steel plate, Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
