Analysis of JIS G3114 atmospheric corrosion resisting steels social inventory

Our company was founded in 2000, which initially committed to providing high-quality steel JIS G3114 atmospheric corrosion resisting steels products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export JIS G3114 atmospheric corrosion resisting steels steel to the international market, opening up the international steel market.

Scope of application of JIS G3101JIS G3114 atmospheric corrosion resisting steels : SS400 steel plates and other steel products are suitable for general structural buildings, bridges and ships, and the final products are hot rolled products.

If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with JIS G3114 atmospheric corrosion resisting steels, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.

During cladding welding of hardfacing wear-resistant steel plate, JIS G3114 atmospheric corrosion resisting steels, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.

JIS G3114 atmospheric corrosion resisting steels, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s JIS G3114 atmospheric corrosion resisting steels domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
