Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and EN 10025-4 S355ML resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, EN 10025-4 S355ML new materials, and promotes the competition of enterprises Struggle.

Our company supply the cold rolled steel coil for customers, and the cold rolled steel coil we produce the standard of JIS, EN, DIN. The available grades include the JIS G 3141 SPCC, SPCD, SPCE, EN 10025-4 S355ML and so on. The EN 10111 standard include DD11, DD12, DD13, DD14. The EN 10130 standard include DC01, DC03, DC04 etc. The standard of DIN 1623 available grades have ST12, US113, RRST13 and ST14.

The wear-resistant plate EN 10025-4 S355ML shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and EN 10025-4 S355ML hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

Vanadium mainly exists in the form of carbide in EN 10025-4 S355ML and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
