Cross Reference Table(Equivalent Grade)
| Grade | Standard | Country | Application |
|---|---|---|---|
| A-2 | AISI | USA | Applied to the thermosetting plastic mold, the hardened mould as a whole |
| Y1Cr18Ni9 | GB | China | Improve the machinability, ablation resistance. Suitable for automatic lathe production of bolt and nut |
| 1Cr18Ni9 | GB | China | High strength after cold forming, but elongation than 1 cr17ni7 slightly worse. Used in architectural decoration parts |
| 1Cr18Mn10Ni5Mo3N | GB | China | Of urea with good corrosion resistance, can produce urea corrosion of the equipment. |
| 1Cr17Ni7 | GB | China | High strength after cold forming. Used in railway vehicle, conveyor belt, bolt and nut, etc |
| Y1Cr18Ni9Se | GB | China | Improve the machinability, ablation resistance. Suitable for automatic lathe production of rivets, screws |
| 0Cr18Ni9 | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
| 00Cr19Ni10 | GB | China | Carbon content lower than 0Cr19ni9 steel, excellent intergranular corrosion resistance, is used for welding after the class is not processed parts |
| 1Cr17Mn6Ni5N | GB | China | Nickel steel grade, instead of number 1 cr17ni7 and magnetism after cold working, used in railway vehicle, etc |
| 1Cr18Mn8Ni5N | GB | China | Nickel steel, instead of 1cr18ni9 |
| 0Cr19Ni9N | GB | China | Based on 0cr19ni9 plus N, strength increase and the plastic is not down. Reduce the thickness of the material. As a structure with strength components |
| 0Cr19Ni10NbN | GB | China | Based on zero cr19ni9 plus N and Nb, with better than 0 cr19ni9 properties and USES |
| 00Cr18Ni10N | GB | China | In 00cr19ni10 adding N, on the basis of the above grades also features, use the same as the 0 cr19ni9n, but better intergranular corrosion resistance |
| 1Cr18Ni12 | GB | China | Compared with 0 cr19ni9, processing low hardenability. Used for spinning processing, special drawing, cold heading |
| 0Cr23Ni13 | GB | China | Corrosion resistance and heat resistance are better than 0cr19ni9 |
| 0Cr25Ni20 | GB | China | Oxidation resistance is better than 0cr23ni13. Mostly used as heat resistant steel |
| 0Cr17Ni12Mo2 | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
| 1Cr18Ni12Mo2Ti | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
| 0Cr18Ni12Mo2Ti | GB | China | Seamless stainless steel tubes for boiler and heat exchanger |
| A-29 1025 | SAE | USA | General use carbon steel rod |
