nm450 wear-resistance steel plate price will be concussive

15CrMo steel belongs to Pearlite Heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature (generally not more than 600 ℃), and has certain hydrogen corrosion resistance. So NM450 wear-resistance steel plate, 15CrMo steel is widely used in petrochemical industry. However, due to the high content of Cr, C and other alloy elements in the steel, the hardening tendency of 15CrMo steel is obvious and the weldability is poor. The main problems are hardening in heat affected zone, cold cracks and reheat cracks during post weld heat treatment.

The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy NM450 wear-resistance steel plate at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent NM450 wear-resistance steel plate products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!

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 NM450 wear-resistance steel plate 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 NM450 wear-resistance steel plate weathering steel is purified and the content of inclusions is greatly reduced.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, NM450 wear-resistance steel plate.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment.
