Hardox 450
SSAB authorised supply
Nominal Hardness 450 HBW
The most versatile abrasion resistant plate in the range. 450 HBW delivers roughly 2.5 times the service life of mild steel while remaining straightforward to bend, cut and weld in a normal workshop.
- 2.5x the wear life of mild steel
- Guaranteed bending and welding properties
- Impact toughness retained down to -40 C
