Material number · Europe · 2 designations # 1.4339 1.4339 is the material number of the grade also listed as GX32CrNi28-10. It is a material in the category Cast stainless steels. We list 2 designations recorded for this grade, in the standards DIN / EN and UNS. - ***Material no.* **1.4339**** - [*Category* **Cast stainless steels · 87 grades**](/categories/cast-stainless-steels "Category: Cast stainless steels · 87 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=3b43b834-703c-4641-8697-3df633912e09 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.4339.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN GX32CrNi28-10 This grade’s own name](/materials/din-en/gx32crni28-10 "DIN / EN GX32CrNi28-10") - [UNS J93303 This grade’s own name](/materials/uns/j93303 "UNS J93303") ## 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. ## Also known as 2 designations · 2 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. DIN / EN Europe · 1 - [GX32CrNi28-10 This grade’s own name](/materials/din-en/gx32crni28-10 "DIN / EN GX32CrNi28-10") UNS United States · 1 - [J93303 This grade’s own name](/materials/uns/j93303 "UNS J93303") Every designation on file is listed — no truncation, no “+ n more”.

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: Mo. ## Physical & mechanical properties Density 7,85 g/cm³ Exact 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. ## Looking for this grade under another name?
