Cutlery steel - CPM S35VN CPM S35VN is a martensitic stainless steel , designed to offer improved toughness over CPM S30V.
It is also easier to machine and polish than CPM S30V.
Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides.
Substituting niobium carbides for some of the vanadium carbides makes CPM S35VN about 15-20% tougher than CPM S30V
without any loss of wear resistance.
CPM S35VN's improved toughness gives it a better resistance to edge chipping.
Because both vanadium and niobium carbides are harder and more effective than chromium carbides
in providing wear resistance, the CPM stainless steels offer improved edge retention
over conventional high chromium steels such as 440C and D2.
The CPM process produces very homogeneous, high quality steel characterized by superior dimensional stability,
grindabilty, and toughness compared to steels produced by conventional melting practices.
