For some special applications,there are two types of tool failure occur in combination,the first one is due to direct contact between working materials and tools during operation,and the second is due to corrosive working conditions.In order to have a satisfied tool life,the tool steel must be highly resistant to corrosion,in addition,it must possess sufficient mechanical properties.

The grades of stainless tool steel produced by HEYE include 11Cr17, 9Cr18Mo, HOP340, HSF340, and the steels are produced by ESR, powder metallurgy or spray forming process, those carefully chosen metallurgical processes make the HEYE products exhibit finer, more uniform carbide distribution imparting improved toughness and grindability.

11Cr17

martensitic stainless steel,high hardness and corrosion resistance, good hardenability,suitable for the manufacture of air conditioning compressor vane, steam turbine blades and valve, bolt used in the condition of erosive medium.

HOP340

martensitic stainless steel, high Cr and high V containing, produced by powder metallurgy process, the carbides is fine and distribut uniformly, better corrosion resistance and wear resistance, suitable for the manufacture of plastic injection and extrusion feed screws, food processing tools, surgical instruments, industrial shear blade, wear-resistant and corrosion-resistant components, etc.
