SFVAF9

SFVAF9 is a grade designated under JIS. Its recorded composition includes C ≤ 0.15%, Si 0.5–1%, Cr 8–10%, Mn 0.3–0.6% and Mo 0.9–1.1%. We list one designation recorded for this grade, in the standard KS. Recorded mechanical properties include Rm 590–760 N/mm², Re 380 N/mm², A 18% and Z 40%; these figures vary with the delivery condition and dimension.

Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade.

The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other.

Physical & mechanical properties

An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material.
