317 stainless steel pipe is a brand of stainless steel produced in accordance with American ASTM standards. Equivalent to my country's 0Cr19Ni13Mo3 stainless steel pipe. 317 contains 19% chromium, 13% nickel, and 3% molybdenum.
Stainless 317 steel pipe has better pitting corrosion resistance than 0Cr17Ni12Mo3 and is used as dyeing equipment materials.
Mechanical properties of 317 steel pipe austenitic steel after solution treatment (GB/T4237-92)
Yield strength ≥205/MPa, tensile strength ≥520/MPa, elongation ≥35%, hardness test: HBS≤187, HRB≤90, HV≤200.
