standard of nm450 wear-resistance Yield Strength

Q420B material is a low-alloy high-strength structural steel. standard of NM450 wear-resistance, Q420 is not high-strength steel, it is still low-carbon steel. Its tensile strength has been improved a bit. The tensile strength of Q235 steel is 235MPa, and the tensile strength of Q420B steel is 420MPa. Q420B low alloy steel has high strength and good fatigue resistance; high toughness and low brittle transition temperature; good Cold forming performance and welding performance; has good corrosion resistance and certain wear resistance.

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, standard of NM450 wear-resistance based on a high starting point and high technology, the company has vigorously developed various steel products standard of NM450 wear-resistance and deep-processed parts, steel structures, precision castings, seamless pipes.

The company selects steel raw materials and controls every quality link from the source to ensure high quality. Each process is strictly checked to ensure that there is zero failure rate in the customer's on-site use. Provide customers with high-quality standard of NM450 wear-resistance products and services with an innovative spirit and work together with customers to create a better future. The company can process and cut various special-shaped parts according to customer needs, and can also customize futures of various material specifications according to requirements.

standard of NM450 wear-resistance controlled rolling is that, on the basis of adjusting the chemical composition of standard of NM450 wear-resistance, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of standard of NM450 wear-resistance.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
