Q420C Chinese steel grade is a low-alloy high-strength structural steel. It not only is high-strength steel, also is low-carbon steel. Q420C low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Product specification GL-A hot-rolled steel strip range: thickness 8-650mm, width 1500-4020mm, length 3000-18800mm
Heat treatment advantages of GL-A hot-rolled steel strip, SA516 Gr 70 pressure vessel steel: 1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased. 2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness. 3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition. 4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.
After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to GL-A hot-rolled steel strip full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our GL-A hot-rolled steel strip steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
ASTM A537 class 1 boiler plate is pressure vessel steel. GL-A hot-rolled steel strip, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.
After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
