Chinese GB and ASME material comparision:
In a boiler that made as per China GB standards, the materials are normally named as per their chemical element composition. This is always make engineers outside China confused. The way of naming is controlled by national standard “GB/T 221-2008 Notations for designations of iron and steel”.
In order to help engineers outside China understand GB, we made the following sheet to compare the common use materials.
| GB | ASME | German DIN |
| Structural Steel Plate | ||
| Q235 | SA-283 gr. C | |
| Q345 | SA-1011 gr. 50 | |
| Pressure Steel Plate | ||
| Q235 | SA-516 gr. 60 | |
| 16Mng/16MnR | 19Mn6/P355GH | |
| Pressure Steel Tube( Carbon Steel & Alloy Steel) | ||
| 20# | SA-106 gr. B | |
| 20G | SA-106 gr. B | |
| 15CrMo | SA-213 T12/SA-335 P12 | 13CrMo 44/ 13CrMo45 |
| 12Cr2Mo | SA-213 T22/SA-335 P22 | |
| 12Cr1MoV | ||
| 10Cr9Mo1VNbN | SA-213 T91/SA-335 P91 | |
| Pressure Steel Tube(Austenite Steel) | ||
| 0Cr18Ni9 | SA-213 TP304 | X5CrNi1810 |
| 06Cr25Ni20 | SA-213 TP310S | |
| 06Cr17Ni12Mo2 | SA-213 TP316 | |
| 1Cr18Ni9Ti | SA-213 TP321 | |
| 1Cr19Ni11Nb | SA-213 TP347H | |
Materials listed in the sheet are equivalent or same on Chemical Composition and Physical performance.
The only difference is sizing. Sizing of materials in GB are using ISO unit, which is millimeter (mm), in ASME is Inch.
