S355J2 carbon steel plate sheet chemical composition and properties

Our quality control department will do inspection for details of the steel materials S355J2 carbon steel plate sheet before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

15CrMo steel is a heat-strength steel and hydrogen-resistant steel widely used in the world. As alloy elements such as Cr and Mo are added to low carbon steel, the comprehensive properties of the steel are greatly improved. For example, it has good high temperature mechanical properties, high temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by S355J2 carbon steel plate sheet metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the S355J2 carbon steel plate sheet steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

Pressure vessel steel plates are mainly used for manufacturing pressure vessels and other similar equipment for gas separation and gas storage and transportation in petroleum and chemical industry. Generally, the working pressure of pressure vessel steel plates ranges from normal pressure to 320kg / cm2 or even 630kg / cm2, and the temperature ranges from - 20 °C to 450 °C. In addition to certain strength, good plasticity and toughness, pressure vessel steel plates must also have good cold bending and welding properties. Q245R, Q345R, 14Cr1MoR, 15CrMoR, S355J2 carbon steel plate sheet etc. are common pressure vessel steel grades.
