Feature:

347 Stainless Steel Tube: 18% chromium, 11% nickel
347 contains tantalum and niobium, mainly used for welded parts used at high temperatures
347 Stainless Steel Pipe = 0Cr18Ni11Nb Nb-containing improves 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 tube heat treatment: solution treatment (℃) 980-1150 fast cooling
Mechanical properties of solution-treated austenitic steel for 347 Stainless Steel Tubes (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 the air or in 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 instead exerts the inherent surface properties of stainless steel. It is used in many A type of steel, commonly referred to as stainless steel. The representative performance is high alloy steel such as 13 chrome steel and 18-8 chrome nickel steel.
From the metallographic point of view, because stainless steel contains chromium, a very thin chromium film is formed on the surface.
In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.
