Which suffix indicates 9% chromium with 1% moly?

Explanation:
Suffix codes on this welding filler-metal family encode the alloy’s chemistry. The code that represents a composition with about 9% chromium and about 1% molybdenum is the one used for that high-temperature, corrosion-resistant stainless family. This 9Cr-1Mo combination is chosen for its oxidation resistance and strength at elevated temperatures, which is why the correct code matches that specific makeup. Other suffixes point to different chromium contents or different alloying schemes, so they wouldn’t correspond to 9% chromium with 1% molybdenum.
