Product Description

Introduction

SKD11 is the tool steel, die steel, and high carbon steel possessing high hardness, strength and
wear resistance. Its surface is grinded precisely. It is often used for the stamping dies, plastic molds,
and so on. JIS SKD11 Tool Steel is a high-carbon and high-chromium alloy tool steel that is used for
making long-life high-precision cold-work dies. SKD11 tool steel has good wear resistance and size
ability after heat treatment. FUSHUN special steel is JIS SKD11 tool steel china supplier and stockholders.

Steel Application

The types of cutting tools are diverse, such as: milling cutter, drill bit, circular saw blade, reamer, PCD (Polycrystalline Diamond) cutting tools, annular cutter, lathe cutting tool, punch cutting tool, etc. The
material quality of woodworking cutting tool usually affects the surface performance of machining,
efficiency, tool life, and other factors. Therefore, the material of woodworking cutting tool should have
the high hardness, wear resistance, sufficient strength, toughness, heat resistance, etc.The materials
of cutting tools we recommend are as below.

Applications

SKD11 Tool Steel is used in the making of knife-edge mold, scissors, circular saw blades, metal
stamping mold. Used to make cold work or hot work dressing dies, sides of rollers, screw lines,
lines dies, transformer core stamping dies, rolled knives, steel tube forming rollers, special molding
rollers, screw heading molds, etc. Also used for blanking dies, stamping dies and pressing dies with
a thickness ≤ 6mm. It can also be found in the production of various kinds of scissors, inlaid blades
and thread rolling dies. It is also used to make wear-resistant slider cold heading dies, deep drawing
molding dies, cold extrusion dies and in the making of thermosetting resin molding dies and common
plastic dies.
