317L stainless steel tube is a brand of stainless steel produced according to the American ASTM standard. It belongs to the heat-resistant steel, and 317L is equivalent to the 00Cr19Ni13Mo3 stainless steel tube in our country. 317 chromium containing 18.0-20.0%, containing nickel 11.0-15.0%, containing molybdenum 3.0-4.0%.

317L stainless steel tube is 0Cr19Ni13Mo3 ultra-low carbon steel, and the intercrystalline corrosion resistance of 0Cr19Ni13Mo3 is better than that of the steel.

Heat treatment of 317L stainless steel tube: solid solution treatment (centigrade) 1010-1150 fast cooling

Mechanical properties of austenitic steel with 317 stainless steel tube treated by solid solution (GB/T4237-92)

The yield strength is more than 177/MPa, the tensile strength is more than 480/ MPa, the elongation is higher than 35%, hardness test: HBS = 187, HRB = 90, HV = 200

317L stainless steel chemical composition: C = 0.08, Si = 1, Mn = 2, P = 0.035, S = 0.030, Ni=11~15, Cr=18.00~20.00, Mo=3~4

A high alloy steel corrosion resistance in the air or chemical corrosion, stainless steel is a beautiful surface and good corrosion resistance, without plating surface treatment, its inherent surface properties of stainless steel, used in many aspects of steel, often called stainless steel. Represents the properties of 13 steel, chromium nickel steel and high alloy steel 18-8.

From metallographical analysis, stainless steel contains chromium to form a thin chromium film on the surface, which separates the oxygen from the steel and acts as an anticorrosive agent.

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

317L stainless steel pipe belongs to ultra low carbon stainless steel, the price of this stainless steel is more expensive than the ordinary stainless steel, but more expensive than the 317L stainless steel plate.

The calculation formula is: (outer diameter - wall thickness) * wall thickness *0.02491= kg / M
