314 Stainless Steel Plate 16Cr25Ni20 Si2 High Temperature Resistance Inox Plate
Stainless steel grade 314 has excellent high-temperature resistance characteristics among the chromium-nickel steels series. The silicon content in this material improves oxidation and carburization resistance; however, it can become very brittle when subjected to prolonged temperatures of 649-816°C (1200- 1500°F).
The following datasheet provides an overview of stainless steel grade 314.
Chemical Composition
The chemical composition of grade 314 steel is outlined in the following table.
| Element | Content (%) |
| Iron, fe | Balance |
| Chromium, Cr | 23-26 |
| Nickel, Ni | 19-22 |
| Manganese, Mn | 2 |
| Silicon, Si | 1.5-3 |
| Carbon, C | 0.25 |
| Sulfur, S | 0.03 |
| Phosphorous, P | 0.045 |
Mechanical Properties
The mechanical properties of grade 314 stainless steel are displayed in the following table.
| Properties | Metric | Imperial |
| Tensile strength | 689 MPa | 99900 psi |
| Yield strength | 345 MPa | 50000 psi |
| Modulus of elasticity | 200 GPa | 29000 ksi |
| Elongation at break (in 50 mm) | 40% | 40% |
| Hardness, Rockwell B | 85 | 85 |
Other Designations
Equivalent materials to grade 314 stainless steel are given below.
| AFNOR Z 12 CNS 25.20 | DIN 1.4841 | UNI X 16 CrNiSi 25 20 | UNI X 22 CrNi 25 20 | JIS SUS Y 31O |
| B.S. 310 S 24 | AMS 5522 | AMS 5652 | ASTM A276 | ASTM A314 |
| ASTM A473 | ASTM A580 | SAE 30314 | SAE J405 (30314) | |
Manufacturing Process
Stainless steel grade 314 can be heat treated by annealing the material at 1038-1149°C (1900-2100°F), and then quenching in water or rapidly air cooling. Grade 314 steel can be hardened only through cold working. To perform machinability of grade 314, coolant and high-speed turning tools are recommended.
After slowly heating the material to 871°C (1600°F), it should be thoroughly soaked, and then followed by quickly heating to 1093 -1232°C (2000-2250°F) , to perform forging, flanging, or working.
Applications
Grade 314 steel is widely used in the following applications:
- Radiant tubes
- Equipment for furnaces
- Heat treatment components
- Annealing and carburizing boxes
