AR500 500 NM500 Abrasion Resistant and Wear Resistant Steel Plate
High strength wear resistant alloy steel plate NM360 NM400 NM450 NM500 AR400 AR500
♦ 1.NM360 wear plate belongs to (wear plate) series, also known as wear-three hundred sixty.
♦2. N is resistant (nai) M is the mill (mo) of two Chinese characters of the first phonetic alphabet, 360 represents the average Brinell hardness of this steel plate.
♦3. Mainly to provide in case of need to wear protection or parts of the device for longer life, reduced maintenance downtime caused by maintenance, into a corresponding reduction of capital.
♦4. Heat treatment: tempering, quenching and tempering (quenching)
♦5. Performance: yield in more than 800, the tensile strength in 1000.
