According to NACE MR0175, compressive stress means exclusion or waiver?
Does Only Loading a Component in Compression Meet the Requirements for Exclusion in MR0175 Part 2, Table 1?
Answer:
The exclusion in MR0175 Part 2, Table 1 applies only to components that are loaded in compression. It does not apply to equipment, assemblies, or aggregate parts that are loaded in compression. However, depending on the part geometry, constraints, bending, friction, or other factors, local stresses within a single component could have a significant tensile element. In these cases, the likelihood of environmental cracking and its consequences must be considered before invoking this exemption.
This Inquiry Pertains to NACE MR0175/ISO 15156-2.
