welding methods of JIS G 3114 grade SMA400BW tensile strength

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to JIS G 3114 grade SMA400BW tensile strength full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our JIS G 3114 grade SMA400BW tensile strength steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.

15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of JIS G 3114 grade SMA400BW tensile strength and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality JIS G 3114 grade SMA400BW tensile strength products and more satisfactory services.
