MAS300 AR Arasion Resistant Steel (300 Brinell)
MAS300 AR is Masteel’s designation for 300 brinell hardness abrasion resistant steel.
The material is a martensitic hardenable steel grade which has excellent strength and hardness characteristics making it resistant to the effects of abrasion and also increased surface pressure.
The steel has a brinell hardness range of 270-390 HBW and has good weldability using conventional welding methods. Heat treatment is not recommended as the process will reduce the hardness, strength and abrasion resistance of the material.
Typical Applications
- Mining machinery
- Earth moving machinery
- Platform structures
- Feeders, hoppers and funnels
Masteel UK Limited can supply MAS300 AR in cut lengths of between 2.5 and 80mm and we can ship to any destination worldwide from our UK steel warehouse.
