heavy steel sheet S690QL carbon mild steel plate

12CrMoV pressure vessel steel is a kind of pearlite heat-resistant steel, which has high structural stability and thermal strength when used for a long time at high temperature. It has low overheating sensitivity during heat treatment and no tendency of temper brittleness; heavy steel sheet S690QL steel has high plasticity and machinability during cold deformation.

Vanadium mainly exists in the form of carbide in heavy steel sheet S690QL and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by heavy steel sheet S690QL 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 heavy steel sheet S690QL 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.

The results of adopting two-level heavy steel sheet S690QL service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and heavy steel sheet S690QL after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
