GENERAL PROPERTIES
317L Stainless Steel Pipe is an exceptional molybdenum-containing, low-carbon austenitic stainless steel. Enhanced with added chromium, nickel, and molybdenum, it offers superior corrosion and chemical resistance, particularly against sulfite, acetic, formic, citric, and tartaric acids. Its low carbon content ensures resistance to sensitization during welding and provides high creep, rupture stress, and tensile strength at elevated temperatures. In its annealed state, 317L Pipe is nonmagnetic, though it may become slightly magnetic after welding.
APPLICATIONS
317L seamless pipe is widely utilized in industries involving sulfur handling, pulp liquors, acid dyes, acetylation and nitration mixtures, bleaching solutions, heavy coal and petroleum, and numerous chemical compounds. Additional applications 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
- ASTM/ASME: UNS N08020
- EURONORM: FeMi35Cr20Cu4Mo2
- DIN: 2.4660
CORROSION RESISTANCE
- Exhibits superior corrosion resistance in challenging environments, including a broad spectrum of chemicals, particularly acidic chloride environments.
- Outstanding resistance in applications where minimal contamination is essential.
- 317L's low carbon content ensures high resistance to intergranular corrosion.
- Effectively combats pitting when exposed to phosphorus acids, chlorides, bromides, and iodides.
HEAT RESISTANCE
- All chromium-nickel-molybdenum steels exhibit excellent oxidation resistance.
- 317L maintains a low rate of scaling in standard atmospheres at temperatures up to 1600-1650°F (871-899°C).
WELDING CHARACTERISTICS
- All common fusion and resistance welding methods, except for oxyacetylene, are 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 nickel-based filler metal with enough chromium and molybdenum to surpass Type 317L's corrosion resistance.
MACHINABILITY
- Low speeds and constant feeds are optimal to minimize work hardening tendencies of this alloy.
- 317L is tougher than 304 stainless, producing long stringy chips; utilizing chip breakers is advisable.
Testing
- We provide a comprehensive range of mechanical tests to assure our product quality. These include expansion tests, hardness tests, micro and macro tests, chemical tests, among others, to ensure maximum customer satisfaction.
