Grade 317 stainless steel is a modified version of 316 stainless steel. It has high strength and corrosion resistance. The following datasheet gives more details about grade 317 stainless steel.
Chemical Composition
The chemical composition of grade 317 stainless steel is outlined in the following table.
| Element | Content (%) |
|---|---|
| Iron, Fe | 61 |
| Chromium, Cr | 19 |
| Nickel, Ni | 13 |
| Molybdenum, Mo | 3.50 |
| Manganese, Mn | 2 |
| Silicon, Si | 1 |
| Carbon, C | 0.080 |
| Phosphorous, P | 0.045 |
| Sulfur, S | 0.030 |
Grade 317 stainless steel is tougher than 304 stainless steel. It is recommended to use chip breakers. Hardenability of this alloy will be reduced if constant feeds and low speeds are used.
Welding
Grade 317 stainless steel can be welded using fusion and resistance methods. Oxyacetylene welding method is not preferred for this alloy. AWS E/ER317 or 317L filler metal can be used to obtain good result.
Hot Working
Grade 317 stainless steel can be hot worked using all common hot working procedures. It is heated at 1149-1260°C (2100-2300°F). It should not be heated below 927°C (1700°F). Post-work annealing can be done to retain the corrosion resistance property.
Cold Working
Stamping, shearing, drawing, and heading can be done successfully. Post-work annealing is performed in order to reduce internal stress.Annealing
Grade 317 stainless steel is annealed at 1010-1121°C (1850-2050°F) followed by cooling.
