Grade equivalent material of nm500 steel machinability

Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, equivalent material of NM500 steel, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the equivalent material of NM500 steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.Tempering the important equivalent material of NM500 steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve equivalent material of NM500 steel strength, plasticity and toughness.Corrosion resistance of stainless steel mainly owes to the formation of a very thin, adhesive and translucent chromium oxide film on the surface of stainless steel. Once the film is damaged, the chromium in the stainless steel will react with oxygen in the atmosphere to restore the film quickly. At the same time, the mechanical damage can also generate a protective film quickly to prevent the equivalent material of NM500 steel, stainless steel from corrosion.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
