X3CrNiMoN27-5-2

X3CrNiMoN27-5-2 is a material in the category Stainless steels, held under material number 1.4460. We list 46 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM, AFNOR, UNE, JIS, GB, GOST, SS and PN. Its recorded composition includes C ≤ 0.05%, Cr 25–28%, Mn ≤ 2%, Ni 4.5–6.5% and Mo 1.3–2%. Recorded mechanical properties include Rm 539–590 N/mm², Re 343–390 N/mm², A 18%, HB 140–277, Z 35–45% and KCU 390–780 kJ/m²; these figures vary with the delivery condition and dimension. Its recorded density is 7.8–7.85 g/cm³. Further recorded physical values: E 136–193 GPa, λ 14.6–25.5 W/(m·K), α 9.5–17.4 ·10⁻⁶/K and ρ el. 700 nΩ·m; several of these are temperature-dependent. Its weldability is recorded as good.

About Stainless steels

Stainless steels are corrosion-resistant alloy steels whose chromium content promotes a protective passive surface film. They are used for equipment, structures and components exposed to moisture, chemicals or hygienic service, with different alloy compositions selected for corrosion resistance, strength, formability or weldability.

This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

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.

Predicted transformation temperatures

This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here.

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.

Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ.

Similar grades — and why

Selection rule, stated so you can disagree with it: same number class 1.4, a shared category, and a published range for Cr / Ni that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
