Properties

317L is a low-carbon stainless steel with increased additions of chromium, nickel and molybdenum for better corrosion resistance than type 316L. This steel resists attack from sulphurous, acetic, formic, citric and tartaric acids as well as combatting the tendency to pit when in contact with phosphorous acid, chlorides, bromides and iodides.

Applications

317L is used to handle sulphur, pulp liquor, acid dyestuffs, acetylating and nitrating mixtures, bleaching solutions, severe coal and oil smoke, and many chemical compounds. Some typical examples include:

* Paper and pulp handling equipment * Textile equipment * Food-processing equipment
