weldability of nm400 plate steel with 15mm thickness

NM series wear-resistant steel plates have uniform hardness, avoid the local fracture phenomenon caused by uneven hardness. Compared with ordinary steel plate, NM360 steel plate has wear resistance of not less than twice, NM400 steel plate has wear resistance of not less than 2.5 times, and NM550 steel plate has wear resistance of not less than 4 times. The wear-resistant steel plate combines the characteristics of high strength, high hardness, weldability and easy bending.

Manganese is used to deoxidize and remove sulfur in steel when making steel. It is an beneficial element in weldability of NM400 plate steel. Manganese has a strong ability to deoxidize and remove sulfur, it can eliminate or reduce the hot brittleness caused by oxygen and sulfur, and improve the strength and hardness of weldability of NM400 plate steel.

From the perspective of market conditions, today weldability of NM400 plate spot prices are operating smoothly, futures are volatile, and market acceptance is average. Merchants have a wait-and-see attitude. Low-price transactions are average, while high-price transactions are poor. Most merchants have daily transactions of 200-300 tons. between. For the market outlook, most merchants adopt the mode of selling more and lowering the warehouse, and are cautious about the later market.

After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to weldability of NM400 plate full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our weldability of NM400 plate steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
