NM500 Abrasion Resistant Steel Plate
NM500 is a kind of high hardness wear-resistant steel material, which has excellent wear resistance and high strength, and is widely used in mining, construction, metallurgy and other industries.
一, what is hardening hardness?
Quenching hardness refers to the hardness of the material obtained during quenching. Quenching changes the crystal structure of a material by heating it to a certain temperature and then cooling it quickly,
Thereby increasing its hardness and strength. Quenching hardness is one of the important indexes to measure the wear resistance of materials.
二, NM500 quenching hardness characteristics
NM500 is a wear-resistant steel material with extremely high hardness, and its quenching hardness reaches 550-600HB(Rockwell hardness). This high hardness gives the NM500 a
Excellent wear resistance, can be used in harsh working environment for a long time without failure.
三, NM500 quenching hardness of the influencing factors
1. Material composition :NM500 is mainly composed of carbon, silicon, manganese, chromium and other elements, reasonable composition ratio can improve the quenching hardness.
2 quenching process: quenching temperature, holding time and cooling speed will affect the quenching hardness. Reasonable quenching process can obtain higher quenching hardness.
3. Quenching medium: Different quenching media have an impact on quenching hardness, commonly used quenching media are water, oil and air.
