ASTM A194
Grade 8MLCuNA
Specialty Stainless Nuts
An Honest Starting Point on This Grade
Grade 8MLCuNA is a genuinely uncommon designation — considerably more specialized than the already-specialty grades we cover elsewhere on our site, like Grade 8N, 8P, or 8MN. Reading the letters suggests a molybdenum-bearing (M), low-carbon (L), copper-bearing (Cu), nitrogen-strengthened (N), strain-hardened (A) stainless composition — each of those elements individually appears in grades we manufacture confidently elsewhere on this site, but we have not encountered this specific five-element combination with enough frequency to state its exact composition, mechanical properties, or even confirm this precise designation appears verbatim in current ASTM A194 editions without you providing the governing text.
We would rather tell you this directly than present false confidence — copper additions in particular are genuinely unusual in mainstream A193/A194 stud and nut families, appearing mainly in a small number of specialty corrosion-resistant grades, and we’d want to see the exact standard reference or project data sheet calling out “8MLCuNA” before committing to composition or mechanical claims.
What we can offer confidently is our manufacturing capability and process — if you can share the governing ASTM A194 edition, a project specification sheet, or an existing mill certificate referencing this exact grade, we will confirm manufacturability, source-verify the composition requirements, and quote accordingly. This is exactly the kind of order we handle as a specification-driven custom manufacture rather than a catalog item.
Akbar Fasteners Pvt. Ltd. exports to over 50 countries and has experience sourcing and manufacturing to unusual, project-specific stainless specifications under our ISO 9001:2015 quality system — we’re glad to work through this one with you directly.
Please Read Before Ordering This Grade
Grade 8MLCuNA is not a designation we can confidently describe from memory. We have not verified this exact combination against a current ASTM A194 standard text at the time of writing this page, and the composition figures a search engine or AI tool might suggest for this grade should not be relied upon without your own verification against the actual governing document.
If you are specifying this grade, please send us the ASTM A194 edition and page/table reference, or your project’s material data sheet, along with your inquiry. We will not quote firm composition or mechanical properties until this is confirmed — this protects both your project and our manufacturing accuracy.
