The -B6 suffix indicates which composition?

The -B6 suffix indicates which composition?

• A. 5% chrome, 1% molly
• B. 5% chrome, 2% molly
• C. 5% nickel, 1% molly
• D. 5% chrome, 0.5% moly

Answer: (A)

The suffix -B6 on filler metal designations encodes its key alloying elements, specifically indicating about 5% chromium and 1% molybdenum. This combination provides corrosion resistance from chromium with added pitting and high-temperature strength from molybdenum, which is why the -B6 designation matches a composition of 5% chromium and 1% molybdenum. The other options would imply different element content (for example, higher molybdenum, or nickel content), which doesn’t align with the -B6 suffix convention.
