NM400 wear-resistant plate is a high-strength wear-resistant steel plate, which has higher wear resistance and better impact performance.
Product introduction
Naming :N is the first pinyin letter of "resistant" in "wear-resistant".
M is the first pinyin letter for "wear" in "wear".
400 is the Brinell hardness number HB value. (The hardness value of 400 is generalized, and the hardness value of domestic NM400 is about 400.)
