347 stainless steel pipe is a grade of stainless steel produced according to the American ASTM standard. 347 stainless steel pipe is equivalent to my country's 0Cr18Ni11Nb stainless steel pipe.
347 stainless steel pipe: contains 18% chromium and 11% nickel
347 contains tantalum and niobium, mainly used for welding parts used at high temperatures
347 stainless steel pipe = 0Cr18Ni11Nb contains Nb to improve intergranular corrosion resistance, with increased strength and no reduction in plasticity. Reduce the thickness of the material. As a structural strength component.
347 stainless steel pipe heat treatment: solution treatment (℃) 980-1150 fast cooling
Mechanical properties of 347 stainless steel pipe after solution treatment of austenitic steel (GB/T4237-92)
Yield strength ≥205/MPa, tensile strength ≥520/MPa, elongation ≥35%, hardness test: HBS≤187, HRB≤90, HV≤200
Chemical composition of 347 stainless steel pipe: C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, S≤0.030, Ni=9~13, Cr=17.00~19.00, Nb≥5*C%
A high alloy steel that can resist corrosion in air or chemical corrosive media. Stainless steel has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as plating, but exerts the inherent surface properties of stainless steel. It is a kind of steel used in many aspects, usually called stainless steel. Representative performance includes high alloy steels such as 13 chromium steel and 18-8 chromium-nickel steel.
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 invades 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.
