Delivery state of p355gh boiler steel specifiction

Pageviews:

P355GH is the European standard pressure vessel plate and sheet. The implementation standard: EN10028-2:2003. p355gh boiler steel specifiction, EN p355gh steel plate and sheet has good plasticity, toughness, cold bending performance and welding performance, suitable for manufacturing nuclear island steel containment, pressure vessels, equipment structural parts, etc. It is delivered in hot rolled, normalized + tempered condition.

Special boiler steel is derived from carbon structural steel, p355gh boiler steel specifiction. 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.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < p355gh boiler steel specifiction steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished p355gh boiler steel specifiction product packaging.

We have a professional production team and high-quality production equipment, and we also have a great p355gh boiler steel specifiction advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the p355gh boiler steel specifiction production of high-quality steel plates, steel pipes and other products that meet customer requirements.
