In F4103, what does the digits '410' denote?

• A. Tensile strength
• B. Yield strength
• C. Hardness
• D. Elongation

Answer: (A)

These numbers are used to convey the strength rating of the material in the designation. The sequence 410 is interpreted as the tensile strength rating—the maximum stress the material is specified to withstand when pulled in tension. This is the primary property engineers rely on when matching materials for welded joints and service loads. The other properties listed—yield strength, hardness, and elongation—are different characteristics and aren’t what this numeric segment is communicating. So the digits point to tensile strength, making that option the best fit.
