FAQs

NACE Standard MR0175 accepts ductile iron to ASTM A 395. Can we use ASTM A 536 Grade 60/40/18?

Question: I have a query regarding material suitability on a recent enquiry to supply a nodular iron screw compressor. NACE Standard MR0175 accepts ferritic ductile iron to ASTM A 395. My question is if our existing in-house standard of ASTM A 536 Grade 60/40/18 will comply as a direct alternative. On the face of it tensile strength, elongation are similar at 415N/mm2 and 18%!

Answer:

The ISO Maintenance Panel cannot advise on materials selection issues. The role of the Maintenance Panel is solely to ensure that NACE MR0175/ISO 15156 (the current edition of NACE MR0175) is clear in its stated requirements and is kept up-to-date.
Should you wish, the procedure to propose an amendment to the standard to include ASTM A 536 Grade 60/40/18 is described in
“01. Introduction to ISO 15156 Maintenance Activities” on the Web site
www.iso.org/iso15156maintenance.

This question is in relation to NACE MR0175/ISO 15156-2 Annex A.2.4.3

Reference: ISO 15156 Maintenance Panel Inquiry #2005-27
