Hi,

For sulphide stress corrosion cracking of any material at high temp and 90 bar pressure if 0.005 mole % H2S is required, is the test same if pressure is reduced to 60 bar and mole% H2S is increased to obtain same partial pressure.   i.e, if we increase mole % H2S and decrease total pressure, is the test condition remain same or alter?
