The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.

GB 3531 09MnNiDR material is Manganese-Nickel alloy steel. The low temperature impacting test shall be done for 09MnNiDR centigrade, the impacting energy value should above 34 J. These EN S460M steel plates are thus tested twice by BBN steel. The tests are conducted to ensure the correct working of the object to know whether there is any change in the properties or not.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. EN S460M steel, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the EN S460M steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After EN S460M steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export EN S460M steel to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.

With the development of China's market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes the group operation, intensive development and lean management, and through a rich series of products and project portfolio as well as a complete operation network, Build the company into a modern enterprise with scientific development concept, continuous innovation vitality, excellent corporate culture, strong sense of social responsibility and international first-class competitiveness.

Both parties shall confirm the EN S460M steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the EN S460M steel steel plant.
