Fabrication
Bisalloy400 is high hardness, abra sion resistant steel offering very good impact toughness properties.
Bisalloy400 provides an optimum combination of abrasion resistant, toughness and weldability. Due to its low alloy content, Bisalloy400 can be readily welded using conventional welding processes and low hydrogen consumables.
Cold forming of Bisalloy400 is achievable on all thicknesses although an allowance for the higher strength should be taken into account. Bending machine capabilities should also be taken into consideration prior to any forming operation. Heating above 250ºC should be avoided, otherwise mechanical properties may be affected.
