Selection of hydrogen sulfide materials in acidic environments

SY/T 0599-2018 Technical specifications for metallic materials used in natural gas surface facilities to resist sulfide stress cracking and stress corrosion cracking
How should any hydrogen sulfide environment with a pH value greater than 6.5 be understood?
1. Under normal conditions, as the pH value increases, the concentration of hydrogen ions decreases, which reduces corrosion of steel. 2. In an alkaline environment with hydrogen sulfide levels of 5000–8000 ppm and a temperature of 330 degrees Celsius, ordinary materials should suffice; is it still necessary to take into account the effects of hydrogen sulfide?
Hello, could you share the standards? Thank you
