Hot Rolled Wear Resistant Abrasion NM500

Naming :N is the first pinyin letter of "resistant" in "wear-resistant".
M is the first pinyin letter for "wear" in "wear".
500 is the Brinell Hardness number HB value. (500 hardness value is a broad sense, the domestic NM500 hardness value is about 500.)
NM500 wear-resistant steel plate is widely used in engineering machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

Product Introduction

Hot Rolled Wear Resistant Abrasion NM500

NM500 steel plate production process:

Production process:

Primary refining →LF refining →VD treatment → Continuous casting (die casting) → cleaning, heating → rolling → (stacking) → surface inspection → Batch → inspection → Heat treatment → cutting sampling → Performance inspection → storage.
