317L stainless steel pipe is according to the ASTM standards to produce a brand of stainless steel.The equivalent of 317L 00Cr19Ni13Mo3 stainless steel pipe in China.317L stainless steel pipe inclusive of our 19% chromium, nickel 317L stainless steel pipe 13%, 13% molybdenum.

317L stainless steel tube spot corrosion resistance is better than 00Cr19Ni13Mo3, do dyeing equipment, materials, etc.

317L stainless steel tube heat treatment: Solid solution treatment (1010 - 1150 鈩? cold quickly.

317L after solid solution treatment of austenite stainless steel tube body of steel mechanical properties (GB/T4237 - 92):

yield strength≥ 205/MPa, strength of extension≥ 520/ MPa, elongation≥ 35%, hardness testing: HBS≤ 187, HRB≤ 90, HV≤ 200

 

Chemical composition of 317 stainless steel pipe:

 

C≤ 0.08, Si≤ 1.00, Mn≤ 2.00, P≤ 0.035, S≤ 0.030, Ni=11~15, Cr=18.00~20.00, Mo=3~4

In air or chemical corrosion resistant to corrosion medium of a kind of high alloy steel, stainless steel is a beautiful surface and corrosion resistant performance is good, need not after surface treatment, such as color of plating and the surface of the stainless steel inherent performance, used in a variety of steel a, often called stainless steel.On behalf of the performance of 13 chrome steel, 18 - 8 chrome - nickel steel high alloy steel.

From the perspective of metallography analysis, because the stainless steel containing chromium and make the surface form very thin chromium film, the film is isolated from intrusion in the steel corrosion of oxygen.

In order to keep inherent corrosion resistance of stainless steel, steel must contain more than 12% of chromium.
