1.2363 equivalent grades: ASTM, EN, JIS, GB, DIN
1.2363 is cold-work tool steel, 5 % Cr air-hardening specified in EN ISO 4957. Substitutes are collected here from 5 standard systems; the grading column says whether a certificate covers the swap or an engineer has to. The full 1.2363 data sheet carries the composition and mechanical tables.

Where a drawing says 1.2363, A2, Cr5Mo1V, SKD12 satisfies it as written, with no concession needed. The near matches are 1.2344; what differs is the tested condition, not the alloy. 1.2379, 1.2842, 1.2767 and 2 more 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 1 in AISI / SAE, 1 in GB/T (China), 1 in JIS (Japan), 5 in EN (European), 1 in GOST (Russia/CIS).
Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| A2 | AISI / SAE | Identical | AISI A2 (UNS T30102, ASTM A681): C 0.95–1.05, Cr 4.75–5.50, Mo 0.90–1.40, V 0.15–0.50. Same steel with a wider molybdenum and vanadium window. |
| Cr5Mo1V | GB/T (China) | Identical | GB/T 1299 Cr5Mo1V is the A2 transcription. |
| SKD12 | JIS (Japan) | Identical | JIS G4404 SKD12: C 0.95–1.05, Cr 4.75–5.50, Mo 0.90–1.20, V 0.15–0.35 — effectively the EN analysis. |
| 1.2344 | EN (European) | Near | X40CrMoV5-1 (H13): nearly the same alloy content with 0.40 % C and 1 % Si. The low carbon makes it a hot-work steel — it cannot reach 60 HRC, but it holds 45 HRC at 550 °C. |
| 1.2379 | EN (European) | Functional | X153CrMoV12 (D2): 12 % Cr and 1.5 % C give far higher abrasive wear resistance and roughly half the toughness. The pair is chosen against each other for every blanking die — see the comparison below. |
| 1.2842 | EN (European) | Functional | 90MnCrV8 (O2): oil-hardening, cheaper, similar toughness but much lower wear resistance and more distortion. Used for short runs and simple tools. |
| 1.2767 | EN (European) | Functional | 45NiCrMo16: the nickel cold-work steel for heavy blanking and cold forging where impact dominates — tougher still, at 54–58 HRC. |
| 1.2510 | EN (European) | Functional | X100CrMoV5 (A2): air-hardening, far less distortion and better wear resistance at a higher price. The standard upgrade when oil-quench distortion becomes the problem. |
| Kh6VF | GOST (Russia/CIS) | Functional | GOST 5950 has no direct 5 % Cr air-hardening grade; Kh6VF (C 1.05–1.15, Cr 5.5–6.5, W 1.1–1.5, V 0.5–0.8) fills the same slot with tungsten instead of molybdenum. |
Identical, near and functional are defined once on the grade index; the reason column below says which limit differs in each case.
