Stainless Steel Pipes.
| Principal Design Features | 317L is a low carbon version of 317 stainless. It possesses the same high strength and corrosion resistance and will produce stronger welds due to its low carbon content. Many users are shifting over to this alloy in lieu of 304 and 316 as availability and cost improves. |
| Applications | Chemical and petrochemical process equipment, pulp and paper manufacturing and condensers in fossil and nuclear fueled power generation stations. |
| Machinability | Low speeds and constant feeds will minimize this alloy's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended. |
| Welding | All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 317L filler metal for best results. |
| Hot Working | All common hot working processes are possible with this alloy. Heat to 2100-2300 F (1149-1260 C). Avoid working this material below 1700 F (927 C). For optimum corrosion resistance, a post-work annealing is recommended. |
| Cold Working | Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended. |
| Annealing | 1850-2050 F (1010-1121 C), followed by rapid cooling. |
| Hardening | This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength. |
Physical Data :
| Density (lb / cu. in.) | 0.29 |
| Specific Gravity | 7.9 |
| Specific Heat (Btu/lb/Deg F - [32-212 Deg F]) | 0.12 |
| Electrical Resistivity (microhm-cm (at 68 Deg F)) | 444 |
| Melting Point (Deg F) | 2550 |
| Modulus of Elasticity Tension | 28 |
Applications
Grade 317L stainless steel is widely used in the following applications:
- Condensers in fossil
- Pulp and paper manufacturing
- Nuclear fueled power generation stations
- Chemical and petrochemical process equipment.
- Stainless Steel Pipes and Stainless Steel Tubes
- Stainless Steel Pipe Fittings
- Stainless Steel Flanges
- Stainless Steel Forgings
