Which mill is good choice for purchasing nm400 steel grade in China

At the same time, the company operates a variety of products of related iron and NM400 steel grade steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained NM400 steel grade ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

The weathering steel plate has outstanding corrosion resistance. Whether it is an offshore drilling platform or a harsh corrosive environment such as the chemical industry, weathering steel plates can effectively prevent corrosion of the plates and extend the service life of the plates. In addition, the weathering steel plate has high strength, fatigue resistance and toughness, which are suitable for various characteristics of construction steel plates. Because of its wide application and large market demand, the price of NM400 steel grade, weather resistant steel plate has attracted more and more attention.

The main metal material NM400 steel grade used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of NM400 steel grade etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in NM400 steel grade etc. steel is strictly controlled.
