weldability of nm400 plate material vs stainless steel

Characteristics and application scope of weldability of NM400 plate, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.

High wear resistance: fully automatic CNC stacking equipment, independent of manual weldability of NM400 plate welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the weldability of NM400 plate hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite weldability of NM400 plate wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.

Most common weldability of NM400 plate steel plates are rolled by hot rolling or controlled rolling. Compared with the general hot rolling process, the advantages of controlled rolling are: the strength and low temperature toughness of steel plates are greatly improved by controlled rolling to refine grains. In addition, the controlled rolling process can give full play to the role of Microalloying Elements Nb, V and Ti, not only play a role of precipitation strengthening, but also refine the grains, and improve the toughness of the rolled weldability of NM400 plate steel plates.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC weldability of NM400 plate steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
