The price performance of wear resistance of nm400 in China

Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, wear resistance of NM400, the impact toughness is also required.

Standing at a new historical starting point, we adapt to the requirements of supply side wear resistance of NM400 structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading wear resistance of NM400 steel materials supplier.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the wear resistance of NM400 steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the wear resistance of NM400 weathering steel is purified and the content of inclusions is greatly reduced.

wear resistance of NM400, Wear-resistant steel plates are composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal circumstances, the thickness of the alloy wear-resistant layer of the wear-resistant steel plate is 1/3-1/2 of the total thickness. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity against external forces. And the alloy wear-resistant layer provides wear-resistant properties to meet the requirements of specified working conditions.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, wear resistance of NM400 deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
