Corrosion resistance of Carbide Steel
Corrosion resistance of Carbide Steel
(OP)
Group,
I have a tool application where the vendor would like to use Carbide Steel #45 in replacement for the speced 416 Stainless Steel. Can anyone tell me the relative corrosion resistance between the two types of steel? Also would be interested to know the relative ferromagnetic properties between the two.
Either material will be coated with TiAlN as a final process.
Part will be used in an outdoor application (worldwide).
Help.
Thanks Craig

RE: Corrosion resistance of Carbide Steel
It rusts very badly outdoors except in the driest of deserts (relative humidity < 25%).
416 is a free-machining, martensitic SS. Lower in Cr, higher in S & C, so inferior to any austenitic SS in corrosion resistance. But, better than any plain carbon steel. Should be OK outside if clean rainfall, no salt, grime or pollution.
Both are ferromagnetic, 1045 probably more so. What magnetic properties are needed?

Maybe my first question should be "anyone know what Carbide steel #45 means?"

416 stainless can be ordered in China as AISI 416 or SUS 416 (the JIS equivalent). China probably has more producers of AISI stainless grades than does the US. You will get the nearest equivalent GB grade, Y1Cr13.
