Based on the advantages of auto steel S 420 MC, S500MC, S700MC 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 auto steel S 420 MC, S500MC, S700MC 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 .

Low carbon alloy steel, the total amount of alloy elements is generally ≦3%; the low carbon alloy steel strength is significantly higher than that of carbon steel, with better plasticity and toughness, and weldability is acceptable; low alloy steel includes carbon manganese series, carbon manganese vanadium series, auto steel S 420 MC, S500MC, S700MC chromium molybdenum series, chromium molybdenum vanadium series. Molybdenum and chromium molybdenum vanadium alloy steels are commonly used as materials for hydrogen corrosion resistance, high temperature sulfur or hydrogen sulfide corrosion resistance and heat resistance (sub high temperature).

Structural steel alloy steel plates are unaffected by high temperatures due to their Molybdenum content, creating rock-like bodies. Combustible industries involve high-temperature procedures, where assemblies made from cheap steel can wither away. Alloy steel sheets auto steel S 420 MC, S500MC, S700MC are robust, recyclable, and have enhanced surface quality. A balance between both Steel and chromium forms DIN 15 Mo3 Alloy Steel plates imperious to oxidation and erosion, with brittle-free hardenability from Steel and Chromium. They don't age or decay, are anti-corrosion and have excellent thermal and heat conductivity.

auto steel S 420 MC, S500MC, S700MC, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.

A283 Grade B steel plate chemical composition:
Carbon, max %: 0.17, Manganese, max %:0.90 , Silicon, max%: 0.15-0.40, Phosphorus max%: 0.035, Sulfur max %: 0.040,Copper min %: 0.20

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, auto steel S 420 MC, S500MC, S700MC and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

Our quality and service commitment: auto steel S 420 MC, S500MC, S700MC product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
