Alloy steel plate/sheet standard of nm450 wear-resistance

40Cr steel is one of the most widely used steels for mechanical operations. The hardenability of this steel is outstanding, it can be hardened to Ф28 ～ 60mm when water quenching, and Ф15 ～ 40mm when oil quenching. In addition to quenching and tempering treatment, 40Cr steel is also suitable for cyanidation and high frequency quenching treatment. 40Cr steel has good cutting performance. When the hardness is 174 ～ 229HB, the relative machinability is 60%. The steel is suitable for making medium-sized plastic molds.

Based on the advantages of standard of NM450 wear-resistance steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel standard of NM450 wear-resistance products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

Quenching Improve the hardness of standard of NM450 wear-resistance steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of standard of NM450 wear-resistance steel and comprehensive mechanical properties.

The main function of boron in standard of NM450 wear-resistance and so on steel is to increase the hardenability of steel, so as to save other rare and precious metals, such as nickel, chromium and molybdenum. For this purpose, the boron content is generally regulated in the range of 0.001% - 0.005%. It can replace 1.6% nickel, 0.3% chromium or 0.2% molybdenum. It should be noted that molybdenum can prevent or reduce temper brittleness, while boron slightly promotes temper brittleness, so molybdenum can not be completely replaced by boron.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel standard of NM450 wear-resistance product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
