400 series and 300 series stainless steel are two common stainless steel series, and they have some significant differences in composition and performance. Here are some of the key differences between 400 series and 300 series stainless steel rods:
| Characteristic | 300 Series | 400 Series |
| Alloy Composition | Austenitic stainless steel withhighernickel and chromium content | Ferritic or martensiti stainless steel with lower nickel content and higher chromium |
| Corrosion Resistance | Excellent corrosionresistance, suitable for corrosive environments | Lower corrosion resistancecompared to 300series,suitable for general industrial applications |
| Strength and hardness | Higher strengthanohardness, suitable for high-stressapplications | Generally lower strengthland hardness compared to 300 series, higher hardness in some grades |
| Magnetic Properties | Mostly non-magnetic | Generally magnetic due to martensitic structure |
| Applications | Food processing,medical equipment,chemical industry | General industrial applications, automotive exhaust systems, kitchenutensils |
