How does the crack on the surface of S355J2WP anti-rust steel plate cause

Our company has S355J2WP anti-rust steel plate strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply S355J2WP anti-rust steel plate deep processing service for products S355J2WP anti-rust steel plate like cutting, drilling, bending, welding and grinding.

This standard ASME SA516 is mainly used to improve the notch toughness important for welding steel plates for pressure vessels. The tensile strength of SA516Gr.60 (HIC) is 415MPa min. The main element content is C Mn Si, P and S control determines its performance. SA516Gr.60 (HIC) chemical composition: C: ≤0.30, Mn: 0.79-1.30, P: ≤0.035, S: ≤0.035, Si: 0.13-0.45. It is a carbon steel material for medium and low temperature pressure vessels.

Compared with ordinary steel, the S355J2WP anti-rust steel plate special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of S355J2WP anti-rust steel plate, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.

The hardness of S355J2WP anti-rust steel plate, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products S355J2WP anti-rust steel plate are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
