30CrMo steel is an alloy structural steel, mainly produced by Chinese steel mills. 30CrMo steel has the advantages of good cutting, moderate cold bending plasticity, high hardenability, good weldability, etc. It is widely used, and 30CrMo equivalents are found all over the world. For example, EN 25CrMo4, AISI 4130, JIS SCM430 and so on.
30CrMo equivalent steel materials:
| China | EU | USA | Germany | France | Italy | Sweden | Czechia | Finland | Japan | Inter |
| GB | EN | - | DIN,WNr | AFNOR | UNI | SS | CSN | SFS | JIS | ISO |
| 30CrMo | 25CrMo4 (1.7218) | SAE4130 | 25CrMo4 | 25CD4 | 25CrMo4 | 2225 | 15130 | 25CrMo4 | SCM430 | 25CrMo4 |
30CrMo equivalent steel materials are mainly for engineering and machine structural use. 30CrMo equivalent has high strength and toughness. The high temperature strength of 30CrMo steel is excellent at temperatures below 500℃.
