1. Basic introduction
446 stainless steel is a high chromium ferritic stainless steel (chromium content of about 23-30%), with excellent high temperature oxidation resistance, corrosion resistance and good mechanical properties. Because of its high chromium content, it is especially suitable for high temperature vulcanization and oxidation environment, but its toughness is low, and it should be avoided in low temperature or impact environment.
2. Main parameters (typical values)
Item parameter value
- Chemical composition of C 0.20% or less, Cr: 23-27% Mn 1.5% or less, Si 1.0% or less, P 0.04% or less, S 0.03% or less, N 0.25% or less
- Density 7.7 g/cm³
- Melting point 1425-1510°C
- Tensile strength ≥515 MPa
- Yield strength ≥275 MPa
- Elongation ≥20%
- Hardness (Brinell) ≤201 HB
- Thermal conductivity 24 W/m·K (20°C)
- Magnetic magnetic (ferrite structure)
3. Main features
- High temperature oxidation resistance: can be used continuously below 1100°C, high temperature oxidation resistance is better than 304/316 stainless steel.
- Corrosion resistance: It has good resistance to nitric acid, organic acid and vulcanization environment, but it is not as resistant to chloride corrosion as austenitic stainless steel.
- Vulcanization resistance: Suitable for sulfur-containing fuel combustion environment (such as boilers, incinerators).
- Disadvantages: low temperature brittleness (avoid using below 0°C), poor welding performance, need to control the heat input.
4. Common specifications
- Thickness: 1.0mm ~ 30mm (cold rolled/hot rolled plate)
- Width: 1000mm ~ 2000mm (conventional)
- Length: 2000mm ~ 6000mm (customizable)
- Surface treatment: 2B (cold rolling bright), No.1 (hot rolling pickling), BA (bright annealing), etc.
5. International standard comparison
Standard system brand
- ASTM UNS S44600
- JIS SUS 446
- GB 1Cr25Mo3Ti (approximate)
- EN 1.4713
6. Typical application areas
- High temperature equipment: furnace components, heat exchangers, annealing hoods, burner nozzles.
- Environmental protection energy: waste incinerator, boiler lining, exhaust pipe.
- Chemical equipment: nitric acid production equipment, pickling tank (avoid chlorine-containing media).
- Others: solar thermal power components, automotive exhaust system high temperature section.
7. Precautions
- Welding: A low heat input process, such as TIG welding, is required and preheated to 150-200°C to reduce the risk of cracking.
- Processing: Annealing (780-850°C) is recommended after cold forming to restore corrosion resistance.
- Avoid: chloride-containing solution and low temperature impact on the environment.
For more specific performance data or selection recommendations, refer to ASTM A240/A240M or consult the material supplier.
