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, astm a573 gr 70 steel 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 layer of wear-resistant steel plate is mainly composed of high-carbon and high-chromium alloy. According to the requirements of different users and service conditions, astm a573 gr 70 steel, the high-temperature wear-resistant steel plate also contains alloy elements such as Mo, W, V, B, Nb, Ti, etc. The microstructure of the wear-resistant layer is eutectic + M7C3-secondary carbide or complex carbide. It can achieve high wear resistance of normal temperature, high temperature, strong impact, medium impact, and low stress impact.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while astm a573 gr 70 steel steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of astm a573 gr 70 steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
We are willing to cooperate sincerely with you with high-quality astm a573 gr 70 steel products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
