The most-used names for this grade.About Cast stainless steels
Cast stainless steels are stainless-steel materials produced by casting, combining corrosion resistance with the ability to form complex component shapes. Their composition and mechanical behaviour vary by grade, and they are used for corrosion-resistant cast components such as pumps, valves and process equipment.
This describes the material class as a whole. Always confirm the individual grade against the standard before ordering.

Chemical composition

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.

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.
