Yield strength ≥205/MPa, tensile strength ≥520/MPa, elongation ≥35%, hardness test: HBS≤187, HRB≤90, HV≤200
Chemical composition of 317 stainless steel round tube: 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
A kind of high-alloy steel that can resist corrosion in the air or chemically corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as color plating, but can utilize the inherent surface properties of stainless steel and is used in many applications. A type of steel, often called stainless steel. Representative performance include 13 chromium steel, 18-8 chromium-nickel steel and other high alloy steels.
From a metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface. This film isolates the oxygen that intrudes into the steel and plays a role in corrosion resistance.
In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.
