AS / NZS · 118 grades # AS / NZS steel grades — 118 designations — Page 3 Every grade designated under AS / NZS, with the material number it maps to, what kind of steel it is, its carbon window and how many other standards carry it. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is an indicative cross-reference, not an asserted identity: the grades are close, not interchangeable. Check the composition before you substitute. ## Also known as 118 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [K1042](/materials/as-nzs/k1042 "K1042") | [1.0503](/materials/material-no/1.0503 "1.0503") | Quenched and tempered steels | 0.42–0.5 | 24 | | [K1045](/materials/as-nzs/k1045 "K1045") | [1.0503](/materials/material-no/1.0503 "1.0503") | Quenched and tempered steels | 0.42–0.5 | 24 | | [K1045](/materials/as-nzs/k1045 "K1045") | [1.1191](/materials/material-no/1.1191 "1.1191") | Quenched and tempered steels | 0.42–0.5 | 21 | | [K1045](/materials/as-nzs/k1045 "K1045") | [1.1191](/materials/material-no/1.1191 "1.1191") | Others | 0.42–0.5 | 18 | | [K1070S](/materials/as-nzs/k1070s "K1070S") | [1.1231](/materials/material-no/1.1231 "1.1231") | Spring steels | 0.65–0.73 | 18 | | [K1095](/materials/as-nzs/k1095 "K1095") | [1.1274](/materials/material-no/1.1274 "1.1274") | Spring steels | 0.95–1.05 | 13 | | [M1020](/materials/aisi-sae/m1020 "M1020") | [1.0402](/materials/material-no/1.0402 "1.0402") | Quenched and tempered steels | 0.17–0.24 | 24 | | [M1040](/materials/as-nzs/m1040 "M1040") | [1.0511](/materials/material-no/1.0511 "1.0511") | Quenched and tempered steels | 0.37–0.44 | 21 | | [S31803](/materials/uns/s31803 "S31803") | [1.4462](/materials/material-no/1.4462 "1.4462") | Stainless steels | ≤ 0.03 | 13 | | [T150](/materials/as-nzs/t150 "T150") | [EN-JL1020](/materials/material-no/en-jl1020 "EN-JL1020") | Others | — | 22 | | [T220](/materials/as-nzs/t220 "T220") | [EN-JL1030](/materials/material-no/en-jl1030 "EN-JL1030") | Others | — | 22 | | [T260](/materials/as-nzs/t260 "T260") | [EN-JL1040](/materials/material-no/en-jl1040 "EN-JL1040") | Others | — | 22 | | [T300](/materials/as-nzs/t300 "T300") | [EN-JL1050](/materials/material-no/en-jl1050 "EN-JL1050") | Others | — | 22 | | [T350](/materials/as-nzs/t350 "T350") | [EN-JL1060](/materials/material-no/en-jl1060 "EN-JL1060") | Others | — | 21 | | [X1345](/materials/as-nzs/x1345 "X1345") | [1.0762](/materials/material-no/1.0762 "1.0762") | Free cutting steels | 0.4–0.48 | 20 | | [XK5155S](/materials/as-nzs/xk5155s "XK5155S") | [1.7176](/materials/material-no/1.7176 "1.7176") | Spring steels | 0.52–0.59 | 18 | | [XK9258S](/materials/as-nzs/xk9258s "XK9258S") | [1.5026](/materials/material-no/1.5026 "1.5026") | Spring steels | 0.52–0.6 | 20 | | [XK9258S](/materials/as-nzs/xk9258s "XK9258S") | [1.0961](/materials/material-no/1.0961 "1.0961") | High-strength multi-phase steels | ≤ 0.18 | 14 | **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.
