mechanical properties of nm550 equivalent steel material in Indian standard

ArcelorMittal USA said mechanical properties of NM550 it was planning to work with the United Steelworkers union "to minimize the impact on its employees. The company will continue to communicate with its customers to understand the market impact of the outbreak of covid-19, which may require additional capacity optimization to maintain a balance between supply and demand.

BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.

Grades mechanical properties of NM550, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the mechanical properties of NM550 steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its mechanical properties of NM550 steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with mechanical properties of NM550, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s mechanical properties of NM550 domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
