ASTM · 2,441 grades # ASTM steel grades — 2441 designations — Page 5 Every grade designated under ASTM, 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 asserted identity — the same grade under this standard’s own designation. 24 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2441 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [A 781 Grade 6A](/materials/astm/a-781-grade-6a "A 781 Grade 6A") Indicative | [1.4410](/materials/material-no/1.4410 "1.4410") | Stainless steels | ≤ 0.03 | 9 | | [A 860 Grade WPHY42](/materials/astm/a-860-grade-wphy42 "A 860 Grade WPHY42") Indicative | [1.0484](/materials/material-no/1.0484 "1.0484") | Others | ≤ 0.17 | 2 | | [A 860 Grade WPHY42](/materials/astm/a-860-grade-wphy42 "A 860 Grade WPHY42") Indicative | [1.0486](/materials/material-no/1.0486 "1.0486") | Fine-grain structural steels | ≤ 0.16 | 6 | | [A 860 Grade WPHY52](/materials/astm/a-860-grade-wphy52 "A 860 Grade WPHY52") Indicative | [1.0562](/materials/material-no/1.0562 "1.0562") | Fine-grain structural steels | ≤ 0.18 | 18 | | [A 860 Grade WPHY52](/materials/astm/a-860-grade-wphy52 "A 860 Grade WPHY52") Indicative | [1.0582](/materials/material-no/1.0582 "1.0582") | Others | ≤ 0.2 | 3 | | [A 860 Grade WPHY60](/materials/astm/a-860-grade-wphy60 "A 860 Grade WPHY60") Indicative | [1.8902](/materials/material-no/1.8902 "1.8902") | Fine-grain structural steels | ≤ 0.2 | 19 | | [A 860 Grade WPHY60](/materials/astm/a-860-grade-wphy60 "A 860 Grade WPHY60") Indicative | [1.8972](/materials/material-no/1.8972 "1.8972") | Others | ≤ 0.21 | 2 | | [A 860 Grade WPHY70](/materials/astm/a-860-grade-wphy70 "A 860 Grade WPHY70") Indicative | [1.8905](/materials/material-no/1.8905 "1.8905") | Fine-grain structural steels | ≤ 0.2 | 14 | | [A-387Cr .
