High strength hardox 500 china supplier steel coil

S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, HARDOX 500 china supplier. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).

Fatigue wear often occurs on the rolling or rolling and sliding friction surface of the wear-resistant plate, HARDOX 500 china supplier. Under the action of alternating stress, the soft area of the surface will produce plastic deformation. When the stress exceeds the tensile strength of the material, cracks will appear in the weak places, and the cracks will continue to expand under the effect of stress. When the crack length reaches a certain value, it will cause fracture and cause the phenomenon of pitting and spalling.

HARDOX 500 china supplier Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.
