weldability of nm400 plate in market price

The steel such as weldability of NM400 plate delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. weldability of NM400 plate, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

Cleveland cliffs, the largest weldability of NM400 plate iron ore company in North America, announced on April 13 that its Northshore mine in Minnesota and Tilden mine in Marquette County, Michigan, will suspend production based on the current market environment. The company said it would reduce inventory levels in both regions, while continuing to weldability of NM400 plate ship iron ore to its customers to meet commercial agreements.

Advantages of weldability of NM400 plate: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
