SS 317L enhanced resistance to chloride pitting and crevice corrosion. Alloy 317L is a low-carbon version of alloy 317, offering enhanced corrosion resistance and better weldability. SS 317L plates and sheets are available in various sizes and thicknesses to meet different industrial needs. This stainless steel grade is particularly suited for chemical processing environments with severe corrosion conditions and where welding operations are frequent.
Applications of SS 317L Plate and Sheet:
- 1. Chemical Processing
- 2. Petroleum Refining
- 3. Pharmaceuticals
- 4. Marine Environments
- 5. Plumbing, HVAC, and fire protection systems.
