The Ultrasonic flaw detection principle of nm300 steel equivalent grades
IS 2062 E450 BR plates which have the quality of good tensile strength, excellent thickness, good elongation, good yield strength. We provide high-end finished products which have accurate dimensions, good durability i.e complete customer satisfaction. Our nm300 steel equivalent grades plates have different applications in a number of industries such as paper, chemical, natural gas, cement industries, oils, shipbuilding etc.
The company attaches great importance to systematic management, and has passed the nm300 steel equivalent grades ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on nm300 steel equivalent grades quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to nm300 steel equivalent grades full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our nm300 steel equivalent grades steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
The main function of boron in nm300 steel equivalent grades 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.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
