Based on the advantages of S355MC cold forming autobobile steel steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel S355MC cold forming autobobile steel products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

Smelting process of S355MC cold forming autobobile steel, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.

High wear resistance: fully automatic CNC stacking equipment, independent of manual S355MC cold forming autobobile steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the S355MC cold forming autobobile steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite S355MC cold forming autobobile steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

The S355MC cold forming autobobile steel, wear resistant steel plate is composed of low carbon steel plate and alloy wear-resistant layer, and the alloy wear-resistant layer is 1/3 ~ 1/2 of the total thickness. The alloy wear-resistant layer and the base plate are metallurgically bonded. When working, the base plate provides comprehensive properties such as strength, toughness and plasticity to resist external forces, and the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

The chemical composition difference between S355MC cold forming autobobile steel, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between S355MC cold forming autobobile steel, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
