Material number · Europe · 31 designations # EN-JS1030 EN-JS1030 is the material number of the grade also listed as EN-GJS-400-15. It is a material in the category Others. We list 31 designations recorded for this grade, in the standards DIN / EN, AISI / SAE, BS, AFNOR, UNE, ISO, JIS, GB, GOST, UNI, SS, ČSN, PN, AS / NZS, BDS, ÖNORM, NBN and SFS. - ***Material no.* **EN-JS1030**** - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **31** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=9b566203-3b12-4cac-8735-d1a93d36fd4a "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/en-js1030.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN EN-GJS-400-15 This grade’s own name](/materials/din-en/en-gjs-400-15 "DIN / EN EN-GJS-400-15") ## About Others These are miscellaneous metallic alloys that do not fit a more specific material family and may be based on iron, nickel, cobalt, copper or other alloy systems. They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 31 designations · 18 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: C, Mn, Si, Ni, Cr, 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. ## Properties by condition 1 conditions · 4 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | Re N/mm² | A5% | HB | |---|---|---|---|---| | Casting, GOST 7293-85 | 400 | 250 | 15 | — | | GOST 7293-85 | — | — | — | 140 – 202 | 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. ## Looking for this grade under another name?
