Top 10 GB stadard of nm500 steel suppliers in China

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and GB stadard of NM500 steel pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters "resistant" and "grind" for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.

The company sold 50,000 tons of hot rolled plates to Southeast Asian countries, which will help the construction of relevant GB stadard of NM500 steel key projects in countries along the “Belt and Road”. In response to the local environment and construction needs in Southeast Asia, the company has made a number of improvements to its export products, with excellent cost performance such as low emissions and low fuel consumption. It is an ideal compaction equipment for the GB stadard of NM500 steel construction of high-grade highways, railways, airports, ports and industrial sites.
