Mild steel impact resistance of nm400 steel plate good mechanical properties

Grade S355J2 is an unalloyed welded structural steel with guaranteed impact work at a temperature of -20ºС. It is used in industrial and civil engineering, as well as in the construction of oil and gas platforms, other offshore structures, power transmission towers and other metal structures. Steel S355J2 is actively used to manufacture elements of heavy ground and underground equipment (bulldozers, excavators and dump trucks), railway wagons and agricultural machinery.

Standing at a new historical starting point, we adapt to the requirements of supply side impact resistance of NM400 steel plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading impact resistance of NM400 steel plate steel materials supplier.

During the steel plate cutting, the special-shaped steel plate cutting process is often carried out. In this operation process, some cutting curves will be generated. Therefore, there should be relatively high precision standards during the processing of impact resistance of NM400 steel plate. The operators need to have rich experience, and they also need to be proficient in the operation methods and working skills of the equipment, so as to ensure that the steel plate can meet the shape requirements after processing.

The addition of Ca element in steel such as impact resistance of NM400 steel plate 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.
