SS 317L Steel Grade Specifications

Grade 317L is a molybdenum-bearing austenitic stainless steel, similar to 316 but with a higher molybdenum content. This gives it significantly higher resistance to chemical attack and pitting.

Key Advantages & Characteristics

✓Higher creep, stress-to-rupture, and tensile strength
✓Superb resistance to chemical attack, especially acidic chlorides
✓Low carbon prevents intergranular corrosion during welding
✓Excellent formability and tough mechanical properties
