SDP2G

SDP2G is a grade designated under JIS. Its recorded composition includes C ≤ 0.25%, P ≤ 0.05% and S ≤ 0.05%. No cross-standard equivalents are recorded for this grade yet. Recorded mechanical properties include Rm 400 N/mm², Re 235 N/mm² and A 17%.

What this alloy is

Iron — the balance, never listed by a standard — 99.7 %C — 0.3 %P — 0.1 %S — 0.1 %

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: Mn, Si, Ni, Cr, Mo.

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.
