NC11LV/1.2379/X153CrMoV12

COLD WORK TOOL STEEL

NORM: ISO 4957

APPLICATION:

The same usage as NC11 steel. Steel susceptible to the tools which require ductile core; such as cutting, punching stamping tools, pull broaches, , mills, shear blades reamers, thread rolling dies, cold extrusion dies rolls for rolling and striking, cutters for nail production, drawing and bending tools, anvils for scythe forging, fine cutting tools, marble, flanging and strengthening tools, moulds for abrasive polymers.
