Prime quality nm450 steel yield strength wear resistant steel plate stock

NM450 steel yield strength, AR400 wear-resistant plate is a special structural steel plate with high wear resistance, and is an important high-tech wear-resistant steel material. After quenching or quenching and tempering heat treatment, AR400 wear-resistant plate has a dense martensite or martensite-bainite microstructure. The thickness of AR400 wear-resistant plate can reach 100mm. The AR400 wear-resistant plate is widely used in loading machinery, construction machinery, agricultural machinery, mining machinery, metallurgy, electric power and other fields.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the NM450 steel yield strength steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of NM450 steel yield strength seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel NM450 steel yield strength can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, NM450 steel yield strength. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
