Leave a message
304 stainless steel and 410 stainless steel are very popular in the market now! GNEE is a professional stainless steel exporter and manufacturer with a history of more than 16 years, with 15000+ tons of standing stock, including stainless steel plates, stainless steel coils, stainless steel pipes, the main grades are 304 316 321 347 and 410 420 430.
Today we will analyze the differences between 304 stainless steel and 410 stainless steel in terms of chemical composition, mechanical properties, corrosion resistance and application fields?
Key Advantages of 304 vs. 410 Stainless Steel
410 stainless steel vs 304 Corrosion resistance:
304 stainless steel: Due to its high nickel content (more than 8%), 304 stainless steel shows excellent corrosion resistance in a variety of environments, especially when exposed to corrosive media such as moisture, acid, alkali, and salt12.
410 stainless steel: Although it also has a certain degree of corrosion resistance, compared with 304 stainless steel, its corrosion resistance may be weaker in specific environments, especially in highly corrosive media.
410 stainless steel vs 304 Strength and Hardness:
410 stainless steel: It is a martensitic stainless steel. After proper heat treatment, its strength and hardness will be significantly improved. It is suitable for occasions that need to bear larger loads or be wear-resistant.
304 stainless steel: Although its strength is relatively low, it has good toughness and tensile resistance.
410 stainless steel vs 304 Heat resistance:
410 stainless steel: It still has good heat resistance at temperatures up to 580°C and is suitable for high temperature environments2.
304 stainless steel: Although it also has a certain degree of heat resistance, its heat resistance will significantly decrease at temperatures exceeding 500°C.
410 stainless steel vs 304 chemical composition
| stainless steel | (C) | (Si) | (Mn) | (P) | (S) | (Cr) | (Ni) |
|---|---|---|---|---|---|---|---|
| 304 | ≤0.08% | ≤1.00% | ≤2.00% | ≤0.045% | ≤0.030% | 18.0 - 20.0% | 8.0 - 10.5% |
| 410 | ≤0.15% | ≤1.00% | ≤1.00% | ≤0.035% | ≤0.030% | 11.50 - 13.50% | - |
304 stainless steel: Contains a high nickel content, providing good corrosion resistance and processability.
410 stainless steel: Does not contain nickel, has high hardness and strength, but relatively poor corrosion resistance.
410 stainless steel vs 304 mechanical properties
| Stainless Steel Type | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Hardness (HRB) |
|---|---|---|---|---|
| 304 | 205 | 520 | ≥40 | ≤200 |
| 410 | 206+ (depends on heat treatment) | 448-655 (depends on heat treatment) | Higher (depends on heat treatment) | Higher (depends on heat treatment) |
Heat treatment： 410 stainless steel can obtain higher hardness and strength, suitable for applications requiring high strength and hardness.
410 stainless steel vs 304 physical properties
| Stainless Steel Type | Structure | Chromium Content (%) | Nickel Content (%) | Carbon Content (%) | Manganese Content (%) | Elongation (%) | Hardness | Corrosion Resistance | Magnetic Properties |
|---|---|---|---|---|---|---|---|---|---|
| 304 | Austenitic | 18-20 | 8-10.5 | ≤0.08 | ≤2 | Good | Lower | Excellent | Non-magnetic (annealed), weakly magnetic (cold-worked) |
| 410 | Martensitic | 11.5-13.5 | ≤0.6 | ≤0.08 | - | Lower |
410 stainless steel vs 304 application areas
304 stainless steel: widely used in food equipment, medical equipment, kitchen utensils and other fields that require contact with corrosive media and require good hygienic performance.
410 stainless steel: Mainly used to manufacture cutting tools, bearings, valves and other mechanical parts that require higher strength and wear resistance.
