MAS500 AR Abrasion Resistant Steel (500 Brinell)
MAS500 AR is a 500 brinell grade steel which is ideal for heavy wear applications commonly found in the mining and earth moving industry.
The material has excellent tensile strength and hardness, infact MAS500 AR has 3 times the hardness of S355 structural steel. The steel has a martensitic micro-structure and whilst heat treatment is not an option (since this would reduce the materials strength and abrasive qualities), MAS500 AR is easy to weld using conventional methods and has good formability.
The material is referred to as a 500 brinell hardness steel – the actual hardness range values for this grade relating to thickness are listed below:
| Grade | Product | Thickness | Hardness Range |
|---|---|---|---|
| MAS500 AR | Cut Lengths | 4.0 - 5.5 | 450 - 540 |
| MAS500 AR | Heavy Plates | 5 - 60 | 450 - 540 |
