Heat Treated Stainless
(OP)
Hi.
Does anyone know what grade of martensitic stainless steel is most commonly used to tooling exposed to water. We are considering 17-4 PH(630) or 440C.
Does anybody have expierence with that - we are looking for grade with high corrosion resistance at room temperature for clean water and good magnetic properties (for easy of machining after heat treating - grinding on magnetic chuck)
Thanks

440C may get flash rust, but that isn't going to affect it's dimensions, unless you're measuring at the micron level.

My concern about flush rusting is that it would become problem after sevetral months of tooling use and tooling will loose its accuracy - we have to maintain it in .0001" range.
