nm450 steel density H beams testing
Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications NM450 steel density high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive NM450 steel density steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.
Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.
As a new type of coil material, compared with the traditional steel coil, NM450 steel density, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.
Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.
The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, NM450 steel density, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.
