What is the S355J2W steel welding hot rolling

Over the years, the company has established a standard of S355J2W steel welding steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to S355J2W steel welding quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

The heat treatment hardness of DC53 mold steel is higher than that of SKD11, S355J2W steel welding, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.

Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the S355J2W steel welding, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.

With the increase of temperature, the yield limit of S355J2W steel welding will decrease monotonically, but the tensile strength of S355J2W steel welding will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S355J2W steel welding. Near the blue brittleness temperature, the S355J2W steel welding strength increases and the plasticity decreases. The elongation and section shrinkage of S355J2W steel welding increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
