Chinese factory manufactured tensile strength of nm500 with good price

Try to use tensile strength of NM500 high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the tensile strength of NM500 temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as tensile strength of NM500. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

The company manages NM400 wear-resistant plate, NM450 wear-resistant plate, tensile strength of NM500, NM500 wear-resistant plate and other wear-resistant plate products. The wear-resistant plates are widely used in many industries, such as engineering, mining, cement, power, construction, machinery, coal, glass manufacturing, paper making, metallurgy, petrochemical, etc.. And the wear-resistant plates are also used in wheel device, grab equipment, bucket body, edge, lining plate, hopper, funnel, bucket valve, etc. parts.

Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.
