Welcome to BBN High Strength Steels Factory
Structural steel S355JR, S355J0, S355J2G, S355J2G4 are low-alloy high-strength structural steels that comply with the European standard EN10025. S355JR steel in China is a low-alloy high-strength structural steel with a hardness of 70-80B and a yield strength of 300-400MPa. S355J2G3 steel is roughly equivalent to GB Q345D. S355J2G3 means that the delivery state is normalized, and the impact energy at -20°C is 27J. G3 and G4 mean the deoxidation method.
The head of the National Development and Reform Commission, He Lifeng, chaired a special meeting of the Office of the Leading Group for the Development of the Yangtze River Economic Belt. The meeting emphasized that the Yangtze River Economic Belt is the center of gravity and vitality of China's economy, and is of great significance to the overall economic and social development of the country. At present, we must focus on four tasks. The first is to make every effort to resume work and achieve production. The second is to make every effort to promote ecological environmental protection and restoration. The third is to strengthen project reserve work. The fourth is to improve the planning guarantee system.
The material 1.8928 processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the material 1.8928 steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
