317L is a premium austenitic stainless steel with enhanced molybdenum content (3.0-4.0%), providing significantly improved corrosion resistance over standard 316L in aggressive chemical environments. The low carbon grade (≤0.03% C) prevents intergranular corrosion in as-welded condition. This makes 317L the material of choice for chemical processing equipment, flue gas desulfurization (FGD) systems, pulp and paper digesters, and food processing involving acidic products.

• Enhanced Molybdenum Content: 3.0-4.0% Mo provides superior resistance to pitting, crevice corrosion, and reducing acid attack
• Superior Sulfuric Acid Resistance: Excellent performance in sulfuric acid concentrations up to 5% at elevated temperatures
• Low Carbon (L-Grade): Maximum 0.03% carbon eliminates sensitization during welding, no post-weld heat treatment required
• Higher Nickel Content: 11.0-15.0% Ni improves resistance to stress corrosion cracking and enhances formability
• Excellent Pitting Resistance: PREN (Pitting Resistance Equivalent Number) ≥ 24.0, outperforming 316L (PREN 23.0)
• Good High-Temperature Strength: Superior creep rupture strength compared to 316L at elevated service temperatures

• Chemical processing vessels, tanks and reactors
• Flue gas desulfurization (FGD) scrubber internals
• Pulp and paper digester and bleach plant equipment
• Food processing equipment handling acidic products
• Pharmaceutical manufacturing equipment and cleanrooms
• Textile dyeing and bleaching equipment
• Petrochemical and refinery sour service components

• Verified Mo Content: Every batch spectrographically tested to confirm 3.0-4.0% molybdenum content
• Corrosion Test Reports: ASTM G48 pitting test and ASTM A262 intergranular corrosion test data available
• Low Carbon Guaranteed: ≤0.03% carbon verified on every heat with full traceability
• Custom Cutting: Precision water jet, laser and plasma cutting to your specified dimensions
• Global Shipping: Experienced in export documentation and packaging for chemical industry standards
