Valast® 400 and Valast® 450 abrasion resistant steel
ABRASION RESISTANT STEEL SHEET FROM HOT ROLLED COIL
Valast® is a registered trademark of Tata Steel and may only be used by Tata Steel or authorized service- and distribution partners
Valast® 400 and Valast® 450 have been developed for applications in construction, mining, agriculture and many other industries. Valast® is extremely wear-resistant with a consistent quality. With a typical hardness of 400 and 450 HBW, the wear resistance is 2.0 to 2.5 times higher than that of an S355 structural steel *.
For users there are advantages such as a longer lifespan and lower maintenance costs. But the production of lighter, more fuel-efficient vehicles with a higher payload is also possible, with reduced use of steel.
The consistent flatness of Valast® enables efficient, reproducible workshop processing steps with improved nesting options for laser cutting, minimal waste and a lower scrap rate. The surface quality also offers opportunities to shorten lead times for subsequent steps in the production process.
