SAE 1010 equivalent grades: ASTM, EN, JIS, GB, DIN
SAE 1010 is low-carbon steel for cold forming, welding and case hardening specified in ASTM A29. Every grade in the database that can stand in for it is listed below, drawn from 3 standard systems, each with the reason it does or does not match exactly. The full SAE 1010 data sheet carries the composition and mechanical tables.

C10, S10C differ on one limit only — a carbon ceiling, an impact temperature or a strength minimum. 1008, 1015 / 1018, DC01 serve the same purpose without being the same steel, so a substitution there needs the design re-checked rather than the certificate. Across systems that is 2 in EN (European), 1 in JIS (Japan), 2 in ASTM / ASME.
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| C10 | EN (European) | Near | EN 10084 C10 / 1.0301: 0.07–0.13 % C, 0.30–0.60 % Mn — the same steel in European designation, used as a case-hardening grade. The EN standard adds hardenability and case-depth requirements that SAE 1010 does not carry. |
| S10C | JIS (Japan) | Near | JIS G4051 S10C: 0.08–0.13 % C, 0.30–0.60 % Mn, Si 0.15–0.35. Practically identical chemistry with silicon specified. |
| 1008 | ASTM / ASME | Functional | SAE 1008 (0.10 % C max) is one step softer and is preferred for the deepest drawing and for wire that will be cold headed. 1010 is the better compromise when the part also has to hold a thread or a form. |
| 1015 / 1018 | ASTM / ASME | Functional | One and two steps up in carbon. 1018 (0.15–0.20 % C) is the usual choice when 1010 is too soft to hold a machined feature — it is the most common carburizing and general machining bar in the US. |
| DC01 | EN (European) | Functional | For cold-rolled sheet the practical European counterpart is DC01 rather than C10, because sheet is specified by forming behaviour, not by bar chemistry. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
SAE 1010 in EN (European)
- C10 — Near EN 10084 C10 / 1.0301: 0.07–0.13 % C, 0.30–0.60 % Mn — the same steel in European designation, used as a case-hardening grade. The EN standard adds hardenability and case-depth requirements that SAE 1010 does not carry.
- DC01 — Functional For cold-rolled sheet the practical European counterpart is DC01 rather than C10, because sheet is specified by forming behaviour, not by bar chemistry.
SAE 1010 in JIS (Japan)
- S10C — Near JIS G4051 S10C: 0.08–0.13 % C, 0.30–0.60 % Mn, Si 0.15–0.35. Practically identical chemistry with silicon specified.
SAE 1010 in ASTM / ASME
- 1008 — Functional SAE 1008 (0.10 % C max) is one step softer and is preferred for the deepest drawing and for wire that will be cold headed. 1010 is the better compromise when the part also has to hold a thread or a form.
- 1015 / 1018 — Functional One and two steps up in carbon. 1018 (0.15–0.20 % C) is the usual choice when 1010 is too soft to hold a machined feature — it is the most common carburizing and general machining bar in the US.
Superseded names for SAE 1010
