Great nm400 steel grade with low price

10CrMo9-10 steel plate is a kind of European standard pressure vessel steel plate, which is heat-resistant and high-pressure resistant boiler steel plate, belonging to alloy pressure vessel steel plate; 10CrMo9-10 steel plate is mainly used for power station boiler drum and steam boiler equipment. The NM400 steel grade delivery state of 10CrMo9-10 steel plate is usually normalizing + tempering.The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.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 NM400 steel grade 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 NM400 steel grade steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.The microstructure of the quenched and tempered alloy steel, NM400 steel grade after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.The company is deeply supported and loved by customers with its unique business philosophy and business model. The company has always been adhering to the "credibility first, integrity-based, quality first" purpose, and sincerely serve new and old customers. Over the past twenty years, the company has won the trust of customers by relying on good service and good reputation. Our aftersales team’s main responsibility is to deal with quality feedback and complaints from Customer.
