The development of heat treatment of p355gh is of great significance

Special boiler steel is derived from carbon structural steel, heat treatment of P355GH. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for heat treatment of p355gh pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common heat treatment of p355gh carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.

The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.
