GENERAL PROPERTIES

The 317L Stainless Steel Pipe, a molybdenum-enriched, low-carbon austenitic stainless steel, boasts superior levels of chromium, nickel, and molybdenum for enhanced resistance to corrosion and various chemicals including sulfite, acetic, formic, citric, and tartaric acids. Its low carbon content ensures resistance to sensitization during welding and offers superior creep resistance, rupture stress, and tensile strength at elevated temperatures. The steel remains nonmagnetic in its annealed state, though slight magnetism may develop post-welding.

APPLICATIONS

The 317L seamless pipe excels in handling sulfur, pulp liquors, acid dyes, acetylation and nitration mixtures, bleaching solutions, heavy coal, and petroleum, as well as numerous chemical compounds. Key applications include:

• Paper and pulp processing equipment
• Chemical and petrochemical processing units
• Condensers in fossil and nuclear power generation stations
• Food processing machinery
• Textile machinery

STANDARDS - ALLOY 317L

• ASTM/ASME: UNS N08020
• EURONORM: FeMi35Cr20Cu4Mo2
• DIN: 2.4660

CORROSION RESISTANCE

• Offers outstanding corrosion resistance in challenging environments, particularly acid chloride settings.
• Ensures excellent resistance in applications where minimizing contamination is crucial.
• The low carbon content makes 317L exceptionally resistant to intergranular corrosion.
• Effectively fights against pitting in the presence of phosphorus acids, chlorides, bromides, and iodides.

HEAT RESISTANCE

• All chromium-nickel-molybdenum steels exhibit exceptional oxidation resistance.
• Shows a low rate of scaling in ordinary atmospheres at temperatures up to 1600-1650°F (871-899°C).

WELDING CHARACTERISTICS

• All typical fusion and resistance welding methods, excluding oxyacetylene welding, have proven highly effective.
• For welding Type 317L steel, use AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with higher molybdenum content than Type 317L, or a nickel-base filler metal with sufficient chromium and molybdenum to surpass the corrosion resistance of Type 317L.

MACHINABILITY

• Maintaining low speeds and constant feeds will reduce the tendency of this alloy to work-harden.
• Tougher than 304 stainless, featuring a long, stringy chip; using chip breakers is recommended.

Testing

• We provide an extensive range of mechanical tests to ensure and guarantee our products' quality. These tests include expansion tests, hardness tests, micro and macro tests, chemical tests, etc., aimed at delivering high satisfaction to our valued customers.
