SFVAF5B

SFVAF5B is a grade designated under JIS. Its recorded composition includes C ≤ 0.15%, Si ≤ 0.5%, Cr 4–6%, Mn 0.3–0.6% and Mo 0.45–0.65%. We list one designation recorded for this grade, in the standard KS. Recorded mechanical properties include Rm 480–660 N/mm², Re 275 N/mm², A 18% and Z 35%; 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.

The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred.

Predicted transformation temperatures

Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni.

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.
