1.4301 vs 1.4571 stainless steel: what’s the difference?
Choosing the right stainless steel grade is essential for long-term performance, especially in environments involving heat, corrosion, or mechanical stress. Two commonly used austenitic grades in Europe are 1.4301 and 1.4571. While they share similarities, key differences in chemical composition and application suitability make them distinct.
What is 1.4571 Steel Equivalent To?
1.4571 is a European (EN) titanium-stabilized austenitic stainless steel grade known for its excellent corrosion resistance and high temperature stability, especially at elevated temperatures. It is commonly used in chemical processing, marine equipment, and heat exchangers.
| Standard System | Equivalent Grade |
|---|---|
| EN (Europe) | 1.4571 |
| AISI / ASTM (USA) | 316Ti |
| UNS (Unified Numbering System) | S31635 |
| DIN (Germany) | X6CrNiMoTi17-12-2 |
| ISO | X6CrNiMoTi17-12-2 |
What Is the Steel Grade 1.4301 Equivalent To?
1.4301 is the most widely used austenitic stainless steel grade in European standards (EN). It has good corrosion resistance, excellent formability and weldability and is commonly used in food processing, construction and general industrial applications.
| Standard System | Equivalent Grade |
|---|---|
| EN (Europe) | 1.4301 |
| AISI / ASTM (USA) | 304 |
| UNS (Unified Numbering System) | S30400 |
| DIN (Germany) | X5CrNi18-10 |
| ISO | X5CrNi18-10 |
1.4301 vs 1.4571 stainless steel: Chemical Composition
| Element | 1.4301 (AISI 304) | 1.4571 (AISI 316Ti) |
|---|---|---|
| Chromium (Cr) | 17.5–19.5% | 16.5–18.5% |
| Nickel (Ni) | 8.0–10.5% | 10.5–13.5% |
| Molybdenum | - | 2.0–2.5% |
| Titanium (Ti) | - | ≥5 × C (stabilizer) |
| Carbon (C) | ≤ 0.07% | ≤ 0.08% |
1.4301 vs 1.4571 stainless steel: Mechanical & Physical Properties
| Property | 1.4301 (304) | 1.4571 (316Ti) |
|---|---|---|
| Tensile Strength (MPa) | 500–700 | 540–750 |
| Yield Strength (MPa) | ≥ 190 | ≥ 230 |
| Elongation (%) | ≥ 45 | ≥ 40 |
| Density (g/cm³) | 7.9 | 8.0 |
| Max Continuous Temp (°C) | ~870°C | ~900°C (better post-weld stability) |
1.4301 vs 1.4571 stainless steel: Corrosion Resistance
1.4301 (304):
Good general corrosion resistance in indoor, atmospheric, and mildly acidic conditions.
Not suitable for strong chlorides or marine environments due to pitting and crevice corrosion risk.
1.4571 (316Ti):
Excellent resistance to chlorides, salts, and acids.
Preferred in marine, chemical processing, and high-temperature welded systems.
The titanium addition prevents sensitization during welding, reducing the risk of intergranular corrosion.
1.4301 vs 1.4571 stainless steel: Cost
The cost difference between 1.4301 (corresponding to 304) and 1.4571 (corresponding to 316Ti) is 30%-50%, because the latter contains molybdenum and titanium to improve performance. 1.4301 is cost-effective for ordinary environments; in high salt spray and high temperature scenarios, 1.4571 has a lifespan 2-3 times longer and a lower full-cycle cost.
