Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| HR1 | BS (superseded British) | Identical | BS 1449-1 HR1 (commercial hot-rolled). |
| IS 1079 D | IS (India) | Identical | IS 1079 grade D (drawing) / O (ordinary); D is the DD11 match. |
| SPHC | JIS (Japan) | Identical | JIS G3131 SPHC: C ≤ 0.15, Mn ≤ 0.60, Rm ≥ 270 MPa, A ≥ 27–31 % by thickness. Commercial hot-rolled forming sheet — SPHD ≈ DD12, SPHE ≈ DD13. |
| CS Type B (A1011) | ASTM / ASME | Near | ASTM A1011 Commercial Steel Type B hot-rolled: C ≤ 0.02–0.15, Mn ≤ 0.60, no guaranteed mechanicals. DS (Drawing Steel) Type B corresponds to DD12/DD13. |
| DD12 | EN (European) | Near | Drawing quality with tighter chemistry and higher elongation. |
| Q195 / SPHC | GB/T (China) | Near | GB/T 5213 hot-rolled uses DD11-type names in newer editions; older specs use Q195 (yield ≥ 195 MPa) or 08Al. |
| 08kp / 08ps hot-rolled | GOST (Russia/CIS) | Near | GOST 16523 group KhP (cold-forming quality) on 08kp/08ps base. |
| St37-2 | DIN (superseded German) | Functional | Hot-rolled forming sheet often bought 'as St37' in Turkey/Middle East — but it has no guaranteed minimum yield. |
| DD13 | EN (European) | Functional | Deep-drawing quality (A ≥ 28–33 %) for demanding pressings. |
| S235JR | EN (European) | Functional | Structural steel of similar chemistry with guaranteed 235 MPa yield and impact; DD11 has no minimum yield guarantee for structural design. |
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.
