The hardox 400 welding chemical composition and application

The salesman of the company is familiar with all aspects of knowledge. Understand the company profile: group, company profile, various honor certification, enterprise's functional strength and other advantages analysis. Know the main product brand types and specifications of the company, and know the special knowledge of the product (production process and advantages of the product, simple identification method of product quality, etc.)

Q370R Pressure Vessel Steel: Steel used to manufacture pressure vessels in petrochemical, gas separation, gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The commonly used steels HARDOX 400 welding are mainly low-alloy high-strength steel and carbon steel. Q370R implements the domestic standard GB713-2008.

Hot rolled HARDOX 400 welding steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the HARDOX 400 welding processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.
