Chronifer M-4057 is a hardenable stainless steel without sulfur. Chronifer M-4057 is manufactured in Rod, Bar and coil (AISI 431 Stainless Steel without Sulphur). For all stock and size availability contact Sales.
AISI 431 has a better corrosion resistance (after hardening and polishing of the parts) then the 420 or 420F because of low carbon and sulfur content, plus so percentage of Nickel and Molybdenum.
