What are the main components of grade S355J0WP steel

The development grade S355J0WP steel of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with grade S355J0WP steel high-quality and efficient services, work together for win-win, and create a better tomorrow!

ST52-3 low alloy steel is equivalent to domestic brand Q345. St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 takes its tensile strength and yield point as its main characteristics. grade S355J0WP steel products are generally used in the manufacture of various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions And other structural parts.

Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. grade S355J0WP steel, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as grade S355J0WP steel. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

EN 10025-2 is standard for hot rolled products of structural steels. EN 10025-2 steel grades are grade S355J0WP steel, S235JR, S235J0, S235J2 (S235 series); S275JR, S275J0, S275J2 (S275 series); S355JR, S355J0, S355J2, S355K2 (S355 series); and S450J0. The numbers 235, 275, 355, 450 indicates the min. yield strength for thickness ≤16mm. For example, when the thickness ≤16mm, the min. yield strength for S235 series steel is 235Mpa, S275 series steel is 275Mpa, S355 series steel is 355Mpa, and S450J0 steel is 450Mpa.
