30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.
NV A36 dry cargo ship steel, P355GH steel yield strength in different thickness has different values.Thickness 8-16mm: 355MPa min., ＞16-40mm: 345MPa min., ＞40-60mm: 335MPa min., ＞60-100mm: 315MPa min., ＞100-150mm: 295MPa min., ＞150-250mm: 280MPa min. The elongation minimum is 20%. P355GH plate under EN10028-2:2003 standard is a pressure vessel steel. It is always delivered in hot rolling, controlled rolling, normalizing.
Special boiler steel is derived from carbon structural steel, NV A36 dry cargo ship steel. 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.
