Now we have been ranked the International leading steel materials supplier.Q415NH steel strip

JIS 3101 SS 540is high strength low alloy steel plate sheet which is widely used in plants building, general mansions and all kinds of construction machinery, such as mines and various types of drilling rig used in construction, power shovel, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers , various types of cranes, hydraulic support, coal mining machinery and equipments and other structures.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance Our shipbuilding steel plate and steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas,Q415NH steel strip.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the alloy wear-resistant steel plate is significantly improved,Q415NH steel strip.

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.
