How to reduce delamination of hardness of nm450 sheet
Since its establishment, the company has always adhered to the enterprise spirit of "solid feet and lofty ideals, dare to create and take responsibility, and dedicate to work". After years of careful management, the company has achieved the double improvement of hardness of NM450 sheet capital strength and scale expansion, gained wide recognition and general praise from all walks of life, further realized specialized and large-scale operation and optimized allocation of resources, and effectively improved the hardness of NM450 sheet overall strength, competitiveness and anti risk ability of the company.
After quenching and tempering, the 40Cr alloy steel plate has good comprehensive mechanical properties, good low-temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28～60mm in water quenching and Ф15～40mm in oil quenching. In addition to quenching and tempering, 40cr sheet is also suitable for cyanidation and high-frequency quenching.
Weathering steel plate hardness of NM450 sheet for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate hardness of NM450 sheet has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. hardness of NM450 sheet, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. hardness of NM450 sheet, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
