|---|---|
| Iron, Fe | 80.49 |
| Chromium, Cr | 17.3 |
| Molybdenum, Mo | 1 |
| Nickel, Ni | 0.3 |
| Manganese, Mn | 0.3 |
| Silicon, Si | 0.3 |
| Titanium, Ti | 0.3 |
| Carbon, C | 0.01 |
436L Stainless Steel Physical Properties
This grade of stainless steel has excellent ductility and toughness thanks to its low carbon content (less than 0.03%). It also boasts high strength (up to 1400 MPa) and good weldability and formability. Additionally, it has a relatively low coefficient of thermal expansion (11 μm/m/K).
436L Stainless Steel Mechanical Properties
Stainless steel 436L offers outstanding tensile strength (up to 760 MPa) and good fatigue resistance. Its hardness ranges from 200 HBW to 300 HBW, depending on the tempering temperature. It also features excellent corrosion resistance in oxidizing and reducing environments due to its high chromium content (>18%) and good oxidation resistance up to 870°C in air. This grade of stainless steel also exhibits excellent resistance to pitting corrosion in seawater applications due to its increased nickel content (>1%).
| Properties | Metric | Imperial |
|---|---|---|
| Tensile strength | 441-517 MPa | 64000-75000 psi |
| Yield strength | 276-345 MPa | 40000-50000 psi |
| Elongation at break | 28-35% | 28-35% |
| Hardness, Rockwell B | 74-85 | 74-85 |
