Cross-reference table
| Grade | System | Match | Why / differences |
|---|---|---|---|
| 16Mo | GB/T (China) | Identical | GB/T 713 16Mo (formerly 16MnMoR-type usage); GB adopted the EN name for Mo pressure plate. |
| A204 Gr. A | ASTM / ASME | Near | ASTM/ASME A204 Grade A (SA-204-A): C ≤ 0.18, Mo 0.45–0.60, yield 255 MPa, Rm 450–585 MPa. Higher Mo than 16Mo3; Grade B (yield 275) is closer on strength. |
| A204 Gr. B | ASTM / ASME | Near | Yield 275 MPa, Rm 485–620 MPa, Mo 0.45–0.60. |
| A335 P1 | ASTM / ASME | Near | Seamless pipe: C 0.10–0.20, Mo 0.44–0.65, yield 205 MPa — the ASME C-½Mo pipe grade corresponding to 16Mo3 tube (EN 10216-2). |
| A182 F1 | ASTM / ASME | Near | C-½Mo forging grade (flanges, fittings). |
| 15KhM / 16M | GOST (Russia/CIS) | Near | GOST 20072 / 5520 grade 16M (Mo 0.25–0.35) is close; 15KhM adds Cr. |
| STPA12 / SB450M | JIS (Japan) | Near | JIS G3462 STPA12 (0.5 Mo pipe) and G3103 SB450M (Mo boiler plate). |
| P265GH | EN (European) | Functional | Non-alloy grade below 400–450 °C; 16Mo3 is the step up. |
| 13CrMo4-5 | EN (European) | Functional | 1.7335 Cr-Mo grade for 500–570 °C and hydrogen service. |
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.
