SAE 1010 equivalent grades: ASTM, EN, JIS, GB, DIN
Cross-reference for SAE 1010 across standard systems. Each match is graded so you can see how safe the substitution is. Low-carbon steel for cold forming, welding and case hardening — full SAE 1010 data sheet.
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 = same composition and mechanical limits within rounding. Near = one limit differs (e.g. carbon max or impact temperature). Functional = interchangeable for most uses after an engineering check.
How the matches are graded
Identical means the chemical composition windows overlap so that material certified to one specification meets the other without deviation, and the mechanical minimums are the same or the other is inside them — mills usually dual-certify. Near means one limit differs (a carbon maximum, an impact temperature, a strength minimum or a delivery condition) and a substitution needs a one-line engineering check. Functional means the grades serve the same purpose but are not the same steel — a designer can often use one for the other, but only after re-checking the design.
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.
