Stock Q310GNH steel strip hot rolled structural

Steel is the main raw material for shipbuilding and marine engineering structure construction, accounting for 20% ~ 30% of the construction cost of hull and marine engineering. The steel products involved mainly include steel plates and section steel (marine bulb flat steel, H-beam, angle steel, etc.), casting and forging steel and supporting welding materials, etc. Among them, the amount of steel consumed for hull construction accounts for about 60% of the total ship mass, and sheet metal accounts for about 88%.

Special boiler steel is derived from carbon structural steel, The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 020% 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,Q310GNH steel strip.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain by rolling method.
