ASSAB 88 Steel

ASSAB 88 Steel

Steel name: ASSAB 88
Diagram No.: 1991
Chemical composition in weight %: 0.90% C, 0.90% Si, 0.50% Mn, 7.80% Cr, 2.50% Mo, 0.50% V
Steel group: Cold work tool steels
Properties: ASSAB 88 is a general purpose steel for cold work tooling. It has a mixed-abrasive wear profile and a good resistance to chipping. Furthermore, a high hardness (>60 HRC) can be obtained after high temperature tempering. This means that surface treatments such as nitriding or PVD can be made on a high strength substrate. It also means that big blocks and complicated shapes with >60 HRC hardness can be wire EDM’d with a much reduced risk of cracking.
Applications: Blanking and fine blanking, shearing, forming, coining, cold forging, cold extrusion, thread rolling, drawing and deep drawing.
Reference: Not shown in this demo version.
