Daxun Alloy is a major maker of stainless steel pipes, and its SS 317/317L seamless pipes are unique. They are renowned for their durability and dimensional correctness. The domestic and worldwide nature of steel raw materials allows for the production of SS 317l pipes in a variety of sizes and thicknesses to meet the individual requirements of business customers. 317L alloy is a low carbon stainless steel with higher chromium, nickel, and molybdenum content than 316L for improved corrosion resistance. This steel is resistant to sulphurous acid, acetic acid, formic acid, citric acid, and tartaric acid, as well as pitting corrosion when exposed to phosphoric acid, chlorides, bromides, and iodides. 317L Stainless Steel Seamless Pipe, 317L Stainless Steel ERW Pipe, 317L Stainless Steel EFW Pipe, and 317L Stainless Steel Welded Pipe and Tube (Conforming to ASTM A213 / A312 / A269 / A358 Standards)
Daxun Alloys has been producing Type 317L Stainless Steel in various sizes and shapes for many years.
We sell 317L alloy that meets or surpasses numerous important international standards, including ASTM, ASME, UNS, DIN, and EN. We also offer SS 317L Tube in a variety of sizes, thicknesses, and specifications based on our customers’ specific needs. Stainless Steel Cold Drawn 317L Tube is a molybdenum-rich austenitic stainless steel, identical to SS 317 but with a greater molybdenum content. SS 317 Tube is available in cut-to-length sizes and can be manufactured or machined to match your specific piping needs. Contact Daxun today.

GENERAL PROPERTIES
317L Stainless Steel Pipe is a molybdenum-containing low-carbon austenitic stainless steel with more chromium, nickel, and molybdenum added for improved corrosion resistance and chemical resistance to sulfite, acetic, formic, citric, and tartaric acids. Due to its low carbon content, 317L Pipe resists sensitization when welded and has higher creep, rupture stress, and tensile strength at elevated temperatures. It is nonmagnetic in the annealed condition, although it may become somewhat magnetic after welding.
APPLICATIONS
317L seamless pipe is commonly used in the handling of sulfur, pulp liquors, acid dyes, acetylation and nitration mixtures, bleaching solutions, heavy coal and petroleum, and many chemical compounds. Some other applications using 317L alloy 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
- 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).
WELDING CHARACTERISTICS
- All common fusion and resistance methods, with the exception of oxyacetylene welding, have proven successful
- AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of Type 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of Type 317L should be used to weld Type 317L steel
MACHINABILITY
- Low speeds and constant feeds will minimize this alloy’s tendency to work harden.
- Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended
Testing
- We offer a wide range of mechanical tests to test and guarantee our products. These tests include expansion tests, hardness tests, micro and macro tests, chemical tests, etc., designed to provide high satisfaction to our valued customers.
