The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating a572 alloy steel vs a656 alloy steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

API2WGr60 material is a special material for pipeline steel. It is mainly used to transport large-diameter welded steel pipes such as oil and natural gas for hot-rolled coils or thick and wide plates. In addition to high compressive strength, it also requires high low temperature toughness and excellent welding performance. As a leading supplier of a572 alloy steel vs a656 alloy steel, API2WGr60 pipeline steel plate in China, our company supply API2WGr60 steel plate, API2WGr60 steel stock and API2WGr60 steel pipe with favourable price.

a572 alloy steel vs a656 alloy steel, Q345 steel has good comprehensive mechanical properties. Q345 steel also has acceptable low temperature performance, good plasticity and weldability. Q345 steel can be used as structures, mechanical parts, building structures and general metal structures bearing dynamic loads such as medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations and bridges. Q345 steel can be used in hot rolling or normalizing state, and can be used in various structures in cold regions below - 40 ℃.

Oxygen (O) is a harmful element in steel such as a572 alloy steel vs a656 alloy steel. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. a572 alloy steel vs a656 alloy steel, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
