2021.02.20 impact resistance of nm400 steel plate industry new technology

Wear resistant steel plate is often used for construction machinery and equipment manufacture, such as excavators, scrapers, sand making machines, etc., which operate repeatedly in the sediment for a long time. That requires the wear resistant steel plate have good wear resistance. Otherwise, once the mechanical equipment is damaged, the progress of the whole project will be greatly affected. impact resistance of NM400 steel plate, Wear resistant steel plate can also be used for building equipment, such as excavation machinery, shovel transport machinery, compaction machinery, engineering lifting machinery, piling machinery, etc.. They need long-term contact with all kinds of sediment, and need the support of wear resistant steel plates.

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 impact resistance of NM400 steel plate 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 impact resistance of NM400 steel plate etc. steel is strictly controlled.

Flat impact resistance of NM400 steel plate steel plate, with a small thickness of the plate. Low carbon equivalent, to adapt to automatic submerged arc welding, plasma welding and other impact resistance of NM400 steel plate welding process requirements.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for impact resistance of NM400 steel plate.
