317L Stainless Steel UNS S31703 Round Pipe
Gnee pipe team
S31703 stainless steel pipe is a chromium-nickel-molybdenum stainless steel with excellent corrosion resistance and high-temperature strength. S31703 acid-resistant pipe has good resistance to pitting corrosion and intergranular corrosion in high-salt environments such as seawater desalination and salt chemical industry.
The surface treatment technology of stainless 317L steel pipe, such as electroplating, phosphating and anodizing, can improve its corrosion resistance and surface hardness. The strength-to-weight ratio advantage of S31703 gives it the advantage of being lightweight in the automobile manufacturing industry.

| 7.9 g/cm3 | 1400 °C (2550 °F) | Psi – 75000 , MPa – 515 | Psi – 30000 , MPa – 205 | 35 % |
317L Stainless Steel Round Pipe
The corresponding domestic and foreign standard grades of S31703 are: UNS S31703; EN 1.4438; JIS SUS317L; 00Cr19Ni13Mo3S31703. During the boring process, the boring speed and feed amount need to be controlled to ensure hole diameter accuracy and surface finish.
The specific chemical composition of 317L stainless steel pipe is: C: ≤ 0.030, Si: ≤ 1.00, Mn: ≤ 2.00, P: ≤ 0.045, S: ≤ 0.030, Cr: 18.00-20.00, Ni: 11.00-14.00, Mo: 3.00- 4.00, N: 0.10-0.22. S31703 seamless stainless steel pipe has good corrosion resistance and cleaning performance in equipment manufacturing in the fields of pharmaceuticals, biotechnology and other fields.
Mechanical properties of S31703 cold drawn steel pipe: tensile strength 550 MPa, yield strength 205 MPa, elongation 35%. Better corrosion resistance can be obtained through coating and other methods. The lattice structure of S31703 stainless thick-walled pipe is face-centered cubic, giving it excellent plasticity and toughness.
