Product Introduction

AR500, 450, and NM400 are all highly wear-resistant steel materials that are commonly used in applications where the material will be exposed to high levels of abrasion.

AR500 steel is a type of abrasion-resistant steel that has a hardness rating of 500 Brinell. It is typically used in applications where the material will be subjected to repeated impacts and abrasions, such as in construction equipment, mining machinery, and military equipment.

450 steel is a heat-treated abrasion-resistant steel that has a hardness rating of 450 Brinell. It is typically used in applications where the material will be subjected to moderate abrasion, such as in material handling equipment, conveyor systems, and agricultural machinery.

NM400 steel is a type of high-strength abrasion-resistant steel that has a hardness rating of 400 Brinell. It is commonly used in applications where the material will be subjected to extreme abrasion and wear, such as in mining equipment, earth-moving machinery, and excavator buckets.
