Susceptible material with SSC/SCC/HIC
(OP)
Does material SS more susceptible of SSC/SCC/HIC than CS? According to NACE MR0175 part-2, P-No. 1 has acceptable with this Standard. In part-3 for SS (P-No. 8) has limitation max parsial pressure of H2S. It's mean for P-No. 1 is acceptable without limitation of max H2S partial press.?

Reviewing this document will help you work through the application of ISO 15156. From it, you should deduce that HIC is not an expected failure mode of an austenitic stainless steel as an example.
However, to answer the last part of your question: there is no maximum H2S partial pressure limit associated with the application of carbon steel.

as SJones said there are also other mechanims of corrosion that you've to consider while selecting a materials.

All design is a compromise between cost, life, risk of failure, likelihood of various corrosion mechanism and manufacturing limitations.
