Q355GNH to GB/T 4171 standard,In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the Q355GNH to GB/T 4171 standard steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.
