A573Gr70 plate technical conditions: the chemical composition and mechanical properties of A573Gr70 steel are produced in line with ASTM A573. When ordering, additional impact, flaw detection, z direction, composition control, performance requirements beyond the standard can be added. Available heat treatment processes of P235GH pipe, A573Gr70 plate: hot rolling, controlled rolling, normalizing, tempering, quenching, normalizing + tempering. Our company supply flaw detection Z15-Z35 thickness direction performance.

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep p235gh pipe processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and p235gh pipe steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the p235gh pipe steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

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 p235gh pipe, 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.
