Do you need standard of nm450 wear-resistance stock

Low alloy structural steel, also known as ordinary low alloy steel, HSLA steel. standard of NM450 wear-resistance, Low alloy steel plates are killed or semi killed steel plates. Low alloy steel plates have the advantages of high strength, better performance, saving material and reducing the weight of structure. The thickness range of low alloy steel plates is usually 4.5-200mm. Low alloy structural steel is mainly used for manufacturing bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures, etc.

Over the years, the company has established a standard of standard of NM450 wear-resistance steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to standard of NM450 wear-resistance quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

Three advantages of semi-endless rolling technology: 1. The limit specification of Q345B steel is expanded from 1.5 mm × 1300 mm to 1.5 mm × 1600 mm. 2. the semi-endless rolling technology can effectively reduce the fluctuations in the temperature, size, and shape control accuracy of the strip head and tail. 3. The different parts of the strip steel standard of NM450 wear-resistance produced by semi-endless rolling have uniform structure and mechanical properties, the yield strength fluctuation is less than 40 MPa, and the tensile strength fluctuation is less than 20 MPa.

Alloying elements can strengthen the properties of structural steels. standard of NM450 wear-resistance, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

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 standard of NM450 wear-resistance products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
