EN10204 Certification for Steel A514 grade B steel material

The mechanical properties of hot rolled steel plate are far less than that of cold working and forging, but the A514 grade B steel material, hot rolled steel plates have better toughness and ductility. Cold rolled steel plate has a certain degree of work hardening and toughness is low, but it can achieve a better yield ratio, and can be used for cold bending spring leaf and other parts. At the same time, because the yield point of cold rolled steel plate is close to the tensile strength, the danger is not foreseen in the use process, and accidents are prone to occur when the load exceeds the allowable load.

Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.

The addition of Ca element in steel such as A514 grade B steel material can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
