Abrasion Resistant Steel Plate ABRAZO 400

Roller quenched steels are used in situations where a combination of high strength and toughness coupled with good weldabilty is required. The main feature of the roller quench process is the use of rotating rolls to hold the plate during quenching, coupled with an extremely efficient quench. Depending on plate thickness and composition, the required rate of cooling is achieved by passing the plate directly through the quench unit or by reciprocating the plate within the unit. The effects of quenching are applied uniformly over the entire plate surface. It is the water curtain, unique to the roller quench unit, which generates the very intense initial cooling rates that achieve the desired properties with very low levels of micro -alloying. The result is a product with improved flatness, greater uniformity of properties, low residual stresses and better weldability Chemical Composition – ABRAZO®400 Content % (ladle analysis), maximum – plates from 8 mm to 80 mm thick*
