stainless steel 17-4 chloride resistance data

[Joe Greulich]

Am looking for a website that has data on chloride and sulfate resistance, to evaluate effects of corrosion. Most of the information I can only says has excellent corrosion data, not actual numbers

 

[EdStainless]

Are you after pitting resistance or cracking resistance?
The HT condition matters a lot, for both factors.
In general 17-4 has so-so corrosion resistance.
No as good as good of pitting resistance as 304, and serious environmental cracking issues unless you are in a H11 or 1150 condition.
