standard of nm450 wear-resistance Typical Application

Characteristics and application scope of standard of NM450 wear-resistance, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.

The company always adheres to the standard of NM450 wear-resistance principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great standard of NM450 wear-resistance cause. Customers are welcome to visit our company at any time. We are always ready to support you.

standard of NM450 wear-resistance annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of standard of NM450 wear-resistance annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. standard of NM450 wear-resistance annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Oxygen is a harmful element in standard of NM450 wear-resistance steel. With the increase of oxygen content, the strength of standard of NM450 wear-resistance steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of standard of NM450 wear-resistance steel.

Our quality and service commitment: standard of NM450 wear-resistance product quality problems, life-long replacement.In the process of using, any time if you find we supplied steel materials not conform to the requirements of technical standards, we can replace it for you free of charge. However, it should be noted that non product quality problems caused by improper use are not covered by the warranty. Please pay attention to the service time commitment as well as the product quality assurance commitment. Because only the products of big brands and reliable enterprises with complete after-sales service system can truly realize the long-term product quality assurance and the whole process of service.
