347 stainless steel is one of the United States in accordance with ASTM standard grades of stainless steel produced. 347 stainless steel equivalent to our 0Cr18Ni11Nb stainless steel plate. 347 stainless steel: chromium 18%, nickel 11% 347 stainless steel containing Nb = 0Cr18Ni11Nb improve resistance to intergranular corrosion, with strength increased, not reduced plasticity. The thickness of the material is reduced. As the structural strength of the part. 347 stainless steel heat treatment: solution treatment (℃) 980-1150 fast-cooling 347 stainless steel mechanical properties after solution treatment of austenitic steel (GB / T4237-92) yield strength ≥205 / MPa, tensile strength ≥ 520 / MPa, elongation of ≥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 capable of withstanding a high-alloy steel, stainless steel is a beautiful surface and good corrosion resistance, do not going through the plated surface treatment, play inherent in the surface properties of stainless steel, used in wide range of steel, often referred to as stainless steel. Representative of the performance of 13 chrome steel, chrome-nickel steel alloy 18-8. From the metallographic point of view, because the stainless steel contains chromium chromium film formed on the surface leaving a thin, the membrane separating oxygen from invading the inner steel corrosion effect. In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 12% chromium.
