Product Description

Product Description

D2/1.2379/SKD11/X38CRMO16/ H12MF/Cr12Mo1V1
COLD WORK TOOL STEEL
APPLICATION:
This material is mainly used in 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.
SPECIFICATION:
Alloyed cold working tool steel with high carbide formers content. It is characterized by high resistance to abrasive wear, greater ductility, extremely low tendency to deformation and hardening cracks, very high hardenability, as well as significant dimensional stability during hardening. In addition, it shows the durability of the blade, even as a result of overheating of the tool during intensive use, thanks to its high chromium content, which contributes to the reduction of thermal conductivity. Another result of the high chromium content is corrosion resistance in air and fresh water.
