Pakistan nm400 material price index
Nickel element is mainly used to form and stabilize the austenite structure, so that the NM400 material steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
In the welding process, effectively preventing the stress and deformation of the component during the welding process is the key to ensuring the welding quality of the wear-resistant steel plate. In the welding process, after spot welding each part according to the position of the drawing, ensure that the size is consistent with the drawing. The welding method of symmetrical multi-layer multi-pass welding is adopted to ensure the appropriate welding process parameters, which can effectively prevent the welding deformation of the NM400 material, wear-resistant steel plate.

Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of NM400 material, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.
