Decision factors of S690QL steel performance

The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.

100Cr6 bearing steel has good toughness, good tempering stability, and small deformation during heat treatment. The carbides in the steel are evenly distributed, it is not easy to precipitate carbide nets, and it is easy to eliminate normalizing. Through normalizing, the network and coarse carbide structures can be eliminated. S690QL steel, 100Cr6 bearing steel can be used to manufacture measuring tools, molds, woodworking tools.

DIN 17100 St37-2 steel plate belongs to the carbon and low alloy high strength steel plate. We can supply the different sizes of S690QL steel, DIN 17100 St37-2 steel plate. And the rolling size of DIN 17100 St37-2 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the DIN 17100 St37-2 steel coil thickness should not exceed 25 mm.

Special boiler steel is derived from carbon structural steel, S690QL steel. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
