Hardenability of hardox 450 astm equivalent after quenching and tempering

At present, China's wear-resistant steel plate grades are divided into six levels, namely NM300, NM360, NM400, NM450, NM500, NM550 and NM600. The wear-resistant steel Hardox 450 astm equivalent grade adopts the combination of Chinese NM of wear resistance meaning and Brinell hardness (HB) value. For example: NM500, NM is the first universal parent of Chinese "wear resistance", "500" is Brinell hardness value. NM series wear-resistant steel has good wear resistance, which greatly reduces the loss and use cost.
