Fabrication
A unique chemical composition and steelmaking process for Bisalloy450 has been developed, incorporating
low carbon/low manganese contents. This is designed to improve transverse mechanical properties and produce low levels of segregation and ensures the newly developed Bisalloy450 not only has superior mechanical properties but also good formability and weldability.
Bisalloy450 can be readily welded using conventional low hydrogen MWAW and GMAW welding consum ables and processes. It can be welded to other weldable steels.
BISALLOY 450 can be cold bent by brake press-bending or roll bend method. However, Bisalloy 450 has higher hardness and strength levels compared to plain carbon steels and therefore suitable consideration of sufficient machine, plate bending direction and former radii must be made. Bisalloy450 should be bent at room temperature or below 200ºC to avoid reduction of mechanical properties.
