What is medium thick nm300 steel high strength sheet
The company adopts the nm300 steel high strength sheet international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety nm300 steel high strength sheet management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.
Q355NHB steel plate is atmospheric corrosion-resistant steel plate, also known as weather-resistant steel plate. It is a low alloy steel series between general steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a few corrosion-resistant elements such as copper and nickel. nm300 steel high strength sheet, Q355NHB steel sheet is featured by good toughness, plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance, etc.
The five advantages of nm300 steel high strength sheet wear-resistant steel plate can reduce its own weight. The steel plate is designed according to the addition of several required alloy elements. Through the special heat treatment method of steel plate, the strength level of nm300 steel high strength sheet steel plate is improved to make it have high hardness (wear resistance) corresponding to various specifications. The result is a significant reduction in the weight of the structure.
The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite nm300 steel high strength sheet, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.
"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. nm300 steel high strength 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.
