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.

Q355NHD is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and D represents quality grade (A, B, C, D, E) composition. P355GH chemical composition steel is an atmospheric corrosion-resistant steel plate with the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature and fatigue resistance.

S960Q plate implements standard EN10025-6S960Q plate application: European standard high-strength steel plate, corresponding to the national standard Q960. p355gh chemical composition, S960Q plate is suitable for manufacturing various construction machinery, such as drilling rigs, electric shovel, electric wheel dump trucks, mining vehicles, excavators, loaders for mining and various engineering construction, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.S960Q plate delivery status: normalizing, normalizing + tempering, quenching and tempering, etc.;Technical requirements for p355gh chemical composition, S960Q plate, p355gh chemical composition: UT, Z15-Z25-Z35 thickness direction performance requirements, high-strength and high-toughness.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This p355gh chemical composition alloy steel p355gh chemical composition still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel p355gh chemical composition plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
