Its recorded composition includes C 0.57–0.65%, Si 0.15–0.35%, Cr ≤ 0.4%, Mn 0.6–0.9% and Ni ≤ 0.4%. We list 7 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, BS, AFNOR and GOST. Recorded mechanical properties include Rm 620–1750 N/mm², A80 17% and HV 195–530; these figures vary with the delivery condition and dimension. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.1211**](/materials/material-no/1.1211 "Material no.: 1.1211") - [*Category* **Spring steels · 52 grades**](/categories/spring-steels "Category: Spring steels · 52 grades") - *Designations* **8** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=fe5f7b00-f7c5-4e54-992c-364639cea4ed&designation=d1503bec-7624-4fba-9cc5-0c8b2a4987a9 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/c60s.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [UNS G10600 This grade’s own name · 12 grades on that route](/materials/uns/g10600 "UNS G10600") - [AISI / SAE 1060 This grade’s own name · 13 grades on that route](/materials/aisi-sae/1060 "AISI / SAE 1060") ## About Spring steels Spring steels are alloy steels designed to store and release elastic energy repeatedly without permanent deformation. They are characterised by a combination of strength, hardness and resilience, making them suitable for springs, clips, washers and other components subjected to repeated flexing or shock. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 8 designations · 6 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## 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 6 conditions · 7 values By thickness**Soft annealed** source `steelnumber` | Thickness mm | Rm N/mm² | A80% | |---|---|---| | 0.3 – 3 | 620 | 17 | By thickness**Cold rolled** source `steelnumber` | Thickness mm | Rm N/mm² | |---|---| | 0.3 – 3 | 1100 | By thickness**Quenched and tempered** source `steelnumber` | Thickness mm | Rm N/mm² | |---|---| | 0.3 – 3 | 1150 – 1750 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HV | |---|---| | Soft annealed | 195 | By delivery state**Cold rolled** source `steelnumber` | Delivery state | HV | |---|---| | Cold rolled | 305 | By delivery state**Quenched and tempered** source `steelnumber` | Delivery state | HV | |---|---| | Quenched and tempered | 345 – 530 | 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 1.1, a shared category, and a published range for Mn / Si 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.
