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. | Grade | Material no. | C | P | S | Mn | |---|---|---|---|---|---| | [SAE 1074](/materials/din-en/sae-1074 "SAE 1074") | [1.9614](/materials/material-no/1.9614 "1.9614") | 0,70-0,80 | 0,03 | 0,05 | 0,50-0,80 | | [SAE 1080](/materials/din-en/sae-1080 "SAE 1080") | [1.9615](/materials/material-no/1.9615 "1.9615") | 0,75-0,88 | 0,03 | 0,05 | 0,60-0,90 | [Previous](/categories/spring-steels "Previous") Page 2 of 2 ## Standards covering this category 25 - [**DIN / EN***34 grades*](/materials/din-en "DIN / EN — 34 grades in this category") - [**JIS***31 grades*](/materials/jis "JIS — 31 grades in this category") - [**AISI / SAE***26 grades*](/materials/aisi-sae "AISI / SAE — 26 grades in this category") - [**UNS***25 grades*](/materials/uns "UNS — 25 grades in this category") - [**GOST***18 grades*](/materials/gost "GOST — 18 grades in this category") - [**KS***16 grades*](/materials/ks "KS — 16 grades in this category") - [**AFNOR***15 grades*](/materials/afnor "AFNOR — 15 grades in this category") - [**BS***14 grades*](/materials/bs "BS — 14 grades in this category") - [**PN***14 grades*](/materials/pn "PN — 14 grades in this category") - [**SRPS***11 grades*](/materials/srps "SRPS — 11 grades in this category") - [**ISO***10 grades*](/materials/iso "ISO — 10 grades in this category") - [**GB***10 grades*](/materials/gb "GB — 10 grades in this category") - [**ČSN***10 grades*](/materials/csn "ČSN — 10 grades in this category") - [**UNI***9 grades*](/materials/uni "UNI — 9 grades in this category") - [**COPANT***8 grades*](/materials/copant "COPANT — 8 grades in this category") - [**BDS***8 grades*](/materials/bds "BDS — 8 grades in this category") - [**STAS***7 grades*](/materials/stas "STAS — 7 grades in this category") - [**ABNT NBR***6 grades*](/materials/abnt "ABNT NBR — 6 grades in this category") - [**SS***5 grades*](/materials/ss "SS — 5 grades in this category") - [**STN***5 grades*](/materials/stn "STN — 5 grades in this category") - [**UNE***4 grades*](/materials/une "UNE — 4 grades in this category") - [**AS / NZS***4 grades*](/materials/as-nzs "AS / NZS — 4 grades in this category") - [**NBN***2 grades*](/materials/nbn "NBN — 2 grades in this category") - [**ASTM***1 grade*](/materials/astm "ASTM — 1 grade in this category") - [**MSZ***1 grade*](/materials/msz "MSZ — 1 grade in this category") ## Property ranges 14 | Property | Unit | Min | Max | Grades | |---|---|---|---|---| | Rm | N/mm² | 620 | 2160 | 18 | | A80 | % | 12 | 17 | 6 | | Re | N/mm² | 440 | 1325 | 6 | | A5 | % | 6 | 21 | 6 | | Z | % | 25 | 45 | 9 | | KCU | kJ/m² | 160 | 160 | 1 | | HB | — | 200 | 321 | 12 | | HV | — | 180 | 630 | 16 | | rho | g/cm³ | 7.43 | 7.85 | 34 | | E | GPa | 191 | 196 | 4 | | Ac1 | °C | 720 | 765 | 6 | | Ac3 | °C | 730 | 810 | 6 | | Ar3 | °C | 770 | 770 | 1 | | Ar1 | °C | 690 | 700 | 4 | Derived from 34 grades in this category with a recorded value. ## Composition range 13 | Property | Unit | Min | Max | Grades | |---|---|---|---|---| | B | % | 0.0008 | 0.0008 | 1 | | C | % | 0.35 | 1.05 | 52 | | N | % | 0.007 | 0.007 | 8 | | Al | % | 0.01 | 0.01 | 5 | | Si | % | 0.1 | 2 | 50 | | P | % | 0.02 | 0.05 | 51 | | S | % | 0.025 | 0.05 | 51 | | V | % | 0.1 | 0.35 | 4 | | Cr | % | 0.1 | 1.5 | 35 | | Mn | % | 0.3 | 1.2 | 52 | | Ni | % | 0.1 | 0.4 | 20 | | Cu | % | 0.12 | 0.3 | 20 | | Mo | % | 0.03 | 0.75 | 14 | Derived from 52 grades in this category with a recorded value. ## Heat treatment 2 | Operation | Min Temperature (°C) | Max Temperature (°C) | Grades | |---|---|---|---| | quenching | — | — | 1 | | tempering | — | — | 1 |
