Product Description
6mm truck beds high hardness nm360 abrasion resistant steel plate sheet
=>N is resistant (nai) M is the mill (mo) the first two Chinese characters phonetic alphabet, 360 represents the average Brinell hardness of this steel sheet
=> NM360 wear-resistant steel is widely used in mining machinery, engineering machinery, mining machinery, environmental protection machinery, also used as a high strength structural steel yield strength over 700MPa.
