This alloy has superior corrosion resistance and is typically used to wrap bleach drums in the pulp and paper mills. The “L” indicates a low carbon content, which significantly improves its welding characteristics. Superior corrosion resistance in i
Alloy 317L is a molybdenum containing, low carbon austenitic stainless steel with increased additions of chromium, nickel, and molybdenum for better corrosion resistance and increased resistance to chemical attack for sulfurous, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L also provides resistance to sensitization when welded and higher creep, stress to rupture, and tensile strength at elevated temperatures. It is non-magnetic in the annealed condition but may become slightly magnetic after welding.
Applications
Alloy 317L is commonly used to handle sulfur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil, and many chemical compounds. Some other applications that use alloy 317L include:
Paper and pulp handling equipment
Chemical and petrochemical processing equipment
Condensers in fossil and nuclear fueled power generation stations
Food processing equipment
Textile equipment
Standards – Alloy 317L
Corrosion Resistance
Demonstrates superior corrosion resistance in difficult environments including a wide range of chemicals, especially in acidic chloride environments
Excellent resistance in applications where contamination is desired to be kept to a minimum
Low carbon content allows 317L to be highly resistant to intergranular corrosion
Combats the tendency to pit when in contact with phosphorus acids, chlorides, bromides, and iodides
Heat Resistance
All chromium-nickel-molybdenum steels all have excellent resistance to oxidation
Demonstrates a low rate of scaling in ordinary atmospheres at temperatures up to 1600-1650°F (871-899°C).
