For NACE MR0175 compliant products, is Carburizing is an acceptable surface treatment process?
Carburizing is not currently permitted in ISO 15156 except in conjunction with the permitted exclusions in Table 1 of ISO 15156-2. These exclusions are associated with specific equipment that is loaded in compression and equipment that is outside the scope of ISO 15156.
This question is in relation to NACE MR0175/ISO 15156-3 Annex A.1.5.1
