SANS · 14 grades # SANS steel grades — 14 designations Every grade designated under SANS, 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. Unless marked, every name here is an indicative cross-reference, not an asserted identity — the grades are close, not interchangeable. 1 of 14 rows differ and carry a “This grade’s own name” mark. ## Also known as 14 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [240 WA](/materials/sans/240-wa "240 WA") | [1.0036](/materials/material-no/1.0036 "1.0036") | Unalloyed structural steels | ≤ 0.17 | 20 | | [240 WA](/materials/sans/240-wa "240 WA") | [1.0037](/materials/material-no/1.0037 "1.0037") | Unalloyed structural steels | ≤ 0.17 | 7 | | [240 WA](/materials/sans/240-wa "240 WA") | [1.0038](/materials/material-no/1.0038 "1.0038") | Unalloyed structural steels | ≤ 0.17 | 26 | | [240 WA](/materials/sans/240-wa "240 WA") | [1.0167](/materials/material-no/1.0167 "1.0167") | Unalloyed structural steels | ≤ 0.17 | 4 | | [240 WC](/materials/sans/240-wc "240 WC") | [1.0114](/materials/material-no/1.0114 "1.0114") | Unalloyed structural steels | ≤ 0.17 | 21 | | [240 WDD](/materials/sans/240-wdd "240 WDD") | [1.0116](/materials/material-no/1.0116 "1.0116") | Unalloyed structural steels | ≤ 0.17 | 12 | | [300 WA](/materials/sans/300-wa "300 WA") This grade’s own name | — | — | — | 1 | | [300 WB](/materials/sans/300-wb "300 WB") | [1.0044](/materials/material-no/1.0044 "1.0044") | Unalloyed structural steels | ≤ 0.21 | 26 | | [300 WC](/materials/sans/300-wc "300 WC") | [1.0143](/materials/material-no/1.0143 "1.0143") | Unalloyed structural steels | ≤ 0.18 | 16 | | [350 WA](/materials/sans/350-wa "350 WA") | [1.0045](/materials/material-no/1.0045 "1.0045") | Unalloyed structural steels | ≤ 0.24 | 17 | | [350 WC](/materials/sans/350-wc "350 WC") | [1.0507](/materials/material-no/1.0507 "1.0507") | Others | ≤ 0.2 | 8 | | [350 WDD](/materials/sans/350-wdd "350 WDD") | [1.0570](/materials/material-no/1.0570 "1.0570") | Unalloyed structural steels | ≤ 0.2 | 22 | | [350WD](/materials/sans/350wd "350WD") | [1.0570](/materials/material-no/1.0570 "1.0570") | Unalloyed structural steels | ≤ 0.2 | 22 | | [350WD](/materials/sans/350wd "350WD") | [1.0595](/materials/material-no/1.0595 "1.0595") | Others | ≤ 0.2 | 7 | **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.
