MR0. 17. 5 addresses all forms of cracking caused by H2. S and applies to equipment using conventional elastic design criteria. The standard addresses requirements and recommendations for the selection and qualification of carbon and low- alloy steels, corrosion- resistant alloys, and other alloys for service in equipment used in oil and natural gas production and natural gas treatment plants in H2.
