Chloride stress corrosion cracking in stainless steel pressure cookers
Chloride stress corrosion cracking in stainless steel pressure cookers
(OP)
As per ASM handbook vol 13, any SS with less then 30 % Ni is prone to chloride SCC. Is it possible in SS pressure cookers since chloride is present in the form of NaCl (common salt) and oxygen is also there. If so are we compromising home safety?
The quantity of chloride and oxygen are sufficient to cause corrssion as per the book's guidelines.

RE: Chloride stress corrosion cracking in stainless steel pressure cookers
For scc to exist, threee condition must exist. high residual stress, hight temperature (above 100C) and the presence of chloride. 18-8 SS sereis is suceptioble if all the previous condition is present.

There's been a major movement from 304 and 316 to 2205 in piping to alleviate the SCC problem.

If you are building pressure cookers for another purpose and they will experience extended time at temperature, duplex SS is far more resistant to CSCC, as stated above but costs about the same as 304 or 316
Happy cooking!
