Cold work tool steel;high carbon,high chromium tool steel,deep hardening,highly wear resistant.It hardens upon air cooling so as to have minimum distortion after heat treatment.
Enduse = blanking or forming dies and thread rolling dies,cutting tools,stamping,woodworking,moulding tools for plastics.
