What is standard of nm450 wear-resistance equivalent European standard

In production and operation, the company always attaches great importance to product standard of NM450 wear-resistance quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market standard of NM450 wear-resistance. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.

High temperature (creep temperature above) boiler steel plate, generally indicates low alloy heat-resistant steel standard of NM450 wear-resistance, the commonly used are chrome molybdenum steel, chrome molybdenum vanadium steel, chrome molybdenum tungsten steel, etc. For example, 15CrMoG and 12Cr1MoVG boiler steel plate in GB713 and gr 22 and gr 91 boiler steel plate in ASME SA387/SA387M. High temperature boiler steel plate standard of NM450 wear-resistance is mainly used to manufacture high temperature pressure parts such as high temperature header end cover, steam pipe plug plate, etc.

With the development of science, technology and industry, higher requirements are put forward for steel materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, abrasion, and other special physical and chemical properties. standard of NM450 wear-resistance, carbon steel can no longer fully meet the requirements, so alloy steel plates appeared. Improving the strength of steel is one of the main purposes of adding alloying elements.

In actual processing applications, the processing standard of NM450 wear-resistance thickness of flame cutting ranges from 6 to 200 mm, and the standard of NM450 wear-resistance cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting standard of NM450 wear-resistance with a certain thickness above 10mm.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
