NACE MR0175 Material Restrictions for Sour Services: Q&A
Why Do Materials with Similar Chemical Composition Have Different Limits for Specific Sour Service Conditions?
This article presents a question-and-answer format related to material restrictions for sour services under NACE MR0175/ISO 15156-3/A.3.2. The question seeks clarification on why materials with similar chemical composition have different limits for specific sour service conditions.
Materials Requirements Based on Metallurgical Conditions
The answer explains that materials requirements are not solely based on chemical composition but also on other metallurgical conditions that impact resistance, such as wrought vs. cast materials. To extend current limits, a ballot with the required testing data or field experience data would be needed.
