DIN / EN · Europe · 4 designations # SAE 1137 SAE 1137 is a material in the category Others, held under material number 1.9737. Its recorded composition includes C 0.32–0.39%, P 0.03%, S 0.08–0.13% and Mn 1.35–1.65%. We list 3 designations recorded for this grade, in the standards UNS, AISI / SAE and JIS. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.9737**](/materials/material-no/1.9737 "Material no.: 1.9737") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **4** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=d78454d3-6916-4ce7-a335-8b7499fa7c80&designation=6987995b-963c-4388-ac8a-0fd4dacceb5b "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/sae-1137.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS G11370 This grade’s own name · 2 grades on that route](/materials/uns/g11370 "UNS G11370") - [AISI / SAE 1137 This grade’s own name · 3 grades on that route](/materials/aisi-sae/1137 "AISI / SAE 1137") ## 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 4 designations · 4 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

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: 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. ## Looking for this grade under another name?
