What Makes SS 317 Sheets Unique?
Stainless Steel 317 (UNS S31700) is a molybdenum-bearing austenitic stainless steel known for its exceptional resistance to pitting, crevice corrosion, and chemical attack. The higher levels of molybdenum and nickel make it superior to the conventional 316 grade, especially in chloride environments.
Chemical Composition:
| Element | Percentage |
|---|---|
| Chromium (Cr) | 18.0 – 20.0% |
| Nickel (Ni) | 11.0 – 15.0% |
| Molybdenum (Mo) | 3.0 – 4.0% |
| Carbon (C) | 0.08% max |
| Manganese (Mn) | 2.0% max |
| Silicon (Si) | 1.0% max |
This unique chemical composition enhances the sheet’s resistance to various acids and ensures its stability under high-stress conditions.
Mechanical Properties of SS 317 Sheets
| Property | Value |
|---|---|
| Density | 8.0 g/cm³ |
| Tensile Strength | 515 MPa min |
| Yield Strength | 205 MPa min |
| Elongation | 40% min |
| Melting Point | 1370–1395°C |
These mechanical features make SS 317 sheets ideal for use in corrosive and high-temperature applications where other materials may fail.
