The company is a leading company that sells automotive steel coil grade S500MC steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold automotive steel coil grade S500MC steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

High-quality alloy steel is made of high-quality carbon structural steel by adding one or several alloying elements (the total mass fraction does not exceed 5%). The alloying elements contained are of different types and contents, and the corresponding properties are also different. High-quality alloy steel is mainly used to manufacture various parts that are larger in size, more complex in shape and difficult to meet performance requirements with high-quality carbon steel. Through proper heat treatment, automotive steel coil grade S500MC, high-quality alloy steel can obtain higher strength and toughness.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The automotive steel coil grade S500MC metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other automotive steel coil grade S500MC alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary automotive steel coil grade S500MC carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized automotive steel coil grade S500MC are higher than that of annealed automotive steel coil grade S500MC, but the elimination of internal stress is not as good as annealing. The normalizing operation of automotive steel coil grade S500MC is simple, the cost is low, the productivity is high, and it is widely used in actual production.

15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of automotive steel coil grade S500MC, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
