    Overview

     

    Based on decades of steel know-how and extensive application knowledge, we have developed Valast® 450 abrasion resistant steel. Designed specifically for use in construction, mining and agriculture equipment. You can rely on Valast 450 to keep performing in the toughest conditions.

    Steel hardness is vital to the development of high performance, abrasion resistant steel. Typically used in tipper bodies, dump trucks, asphalt pavers, chutes, garbage trucks, containers, excavator buckets and many more applications, this steel must withstand severe wear and tear to extend their operational life and minimise repair and replacement costs.

    Reliable quality, together with the widest abrasion resistant strip dimensions on the market, result in multiple benefits for your processing operations – with scope to boost yield and cut waste. Thoroughly tested, fully accredited and available only via a proven supply chain, Valast 450 gives you extra value.
     

    Product features

      

    Weldability

    Tata Steel’s investment in a research and development programme has ensured a low CET of less than 0.33 in  Valast 450 steel – ensuring that all conventional welding methods can be used.

    CEV max CET max PCM max
    0.45 0.33 0.32


    Surface

    Valast 450 hot-rolled strip offers superior surface quality when compared with reversing mill plate in ‘as rolled’ condition.
