347 stainless steel is produced in accordance with ASTM standards of the United States a grade of stainless steel. 347 stainless steel is equivalent to our 0Cr18Ni11Nb stainless steel.
347 stainless steel: chromium 18%, 11% nickel
347 stainless steel containing Nb = 0Cr18Ni11Nb increase resistance to intergranular corrosion, has improved strength, ductility is not reduced. Reduce the thickness of the material. As the structural strength of components
347 stainless steel heat treatment: solution treatment (℃) 980-1150 fast-cooling
347 stainless steel after solution treatment of austenitic steel mechanical properties (GB/T4237-92)
Yield strength ≥ 205/MPa, tensile strength ≥ 520 / MPa, elongation ≥ 35%, hardness test: HBS ≤ 187, HRB ≤ 90, HV ≤ 200
347 stainless steel chemical composition: 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%
In the air or chemical corrosion medium corrosion resistant to a high alloy steel, stainless steel is a beautiful surface and good corrosion resistance, without going through the plated surface treatment, and play inherent in the surface properties of stainless steel, for use in multi-areas of steel, often referred to as stainless steel. Representative of the performance of 13 chrome,18-8 chrome-nickel steel, high alloy steel.
From the metallographic point of view, because leaving the surface of stainless steel containing chromium chromium thin film, the film within the invasive isolate oxygen and steel from corrosion effect.
In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium
