NM400耐磨板有哪些优点是什么?

  The high-strength NM400 wear-resistant plate is achieved by adding different alloy elements to achieve solid solution strengthening, grain boundary strengthening and second phase strengthening of the matrix structure. It has presented low-alloy martensite steel, bainite steel, and austenite. Duplex/Bainite Duplex Steel, Martensite/Bainite Duplex Steel, etc. In recent years, with silicon as the main alloying element, the use of silicon has strongly suppressed the characteristics of carbide separation during the bainite transformation process.

  An austenite-biphasic structure composed of carbide-free bainite ferrite and residual austenite stabilized by carbon and silicon can be obtained. Since carbide-free eliminates the cause of cracking or spalling, it has excellent strength The inductive mechanical function of resistance is now the most popular new generation of wear-resistant material in the world, with the following advantages: yield strength, high tensile strength and good ductility.

  NM400 wear plate has high strength and high fracture resistance; high impact strength; excellent wear resistance. The high-strength NM400 wear-resistant plate has a special heat treatment process. The steel has both high strength and high resistance, and excellent casting processability. Compared with high manganese steel and high chromium steel, the wear resistance is improved by more than 2 times. The ultra-high-strength NM400 wear-resistant plate is alloyed by rare earth transformation, and after a certain process, nano-scale bainite/martensite complex phase structure is obtained.

NM400.铁盘子具有1950MPa的拉伸强度,折断折射率为17%,缩短率为38%,HRC55,AKU72J,耐久性耐力诱导功能优异,理论研究价值极强,使用促销价值。钢具有良好的机械加工功能,铸造功能和焊接功能。在等温淬火后,强塑料产品达到51gPa%。高应变速率变形弹道检测表示。

  The characteristics of NM400 plates are mainly used in environmental parts such as mines, construction machinery, strong wear and tear; open-pit mine shovel teeth, bucket teeth, excavator factory supporting shovel teeth, etc.; vehicles, iron tracks, power, communications, mechanical equipment , Mining machinery, picks, hydraulic equipment, transmission equipment, high-strength standard parts, etc.; high-strength bolts, wear-resistant wire mesh, steel reinforcement for coastal bridges and high-strength equipment, etc.
