What is the difference between 1.4306 and 1.4016 stainless steel?
1.4306 Stainless Steel (Equivalent to AISI 304L) vs. 1.4016 Stainless Steel (Equivalent to AISI 430)
While both 1.4306 and 1.4016 stainless steels belong to the family of ferritic and austenitic steels, they have significant differences in terms of chemical composition, mechanical properties, corrosion resistance, and applications.

1.4306 Stainless Steel (AISI 304L)
1.4306, also known as AISI 304L, is an austenitic stainless steel that contains higher levels of nickel and chromium. This provides it with excellent corrosion resistance and ductility. It is commonly used in applications where strength and corrosion resistance are crucial.
1.4016 Stainless Steel (AISI 430)
1.4016, or AISI 430, is a ferritic stainless steel that contains lower amounts of nickel than 1.4306. It is known for being a more economical option with good corrosion resistance, but its mechanical properties and resistance to extreme environments are lower than austenitic grades.
1.4306 vs 1.4016 Stainless Steel: What's the Difference?
| Property | 1.4306 Stainless Steel (AISI 304L) | 1.4016 Stainless Steel (AISI 430) |
|---|---|---|
| Stainless Steel Type | Austenitic | Ferritic |
| Main Alloying Elements | Cr: 17–19% Ni: 8–12% C: ≤0.030% |
Cr: 16–18% Ni: ≤0.75% C: ≤0.12% |
| Magnetic Properties | Non-magnetic (slightly magnetic after cold working) | Magnetic |
| Density | 7.93 g/cm³ | 7.70 g/cm³ |
| Tensile Strength | 500–700 MPa | 450–600 MPa |
| Yield Strength | ≥190 MPa | ≥210 MPa |
| Elongation (A5) | ≥40% | ≥18% |
| Hardness (HRB) | ≤80 | 80–90 |
| Corrosion Resistance | Excellent – suitable for chemical, marine, and food applications | Moderate – suitable for indoor, decorative, and appliance uses |
| High Temperature Resistance | Continuous up to ~870°C, intermittent up to 925°C | Continuous up to ~815°C, intermittent up to 870°C |
| Weldability | Excellent – low carbon content reduces intergranular corrosion | Poor – prone to heat cracking without proper precautions |
| Typical Applications | Chemical processing, pressure vessels, food industry, medical equipment | Kitchen appliances, dishwasher panels, decorative trim |
Magnetic Properties:
1.4306 is non-magnetic in the annealed condition, ideal for applications where magnetism must be avoided (such as in food processing).
1.4016 is magnetic, making it suitable for applications where magnetism is either not a concern or needed for specific purposes.
