347 stainless steel rod 

 Is produced according to U.S. ASTM standards of a stainless steel grades. 347 stainless steel rod is equivalent to our 0Cr18Ni11Nb stainless steel rod. 347 stainless steel rod: chromium 18%, nickel 11% of the 347 stainless steel rod = 0Cr18Ni11Nb of Nb to improve resistance to intergranular corrosion, high strength increased, the plastic is not reduced. Reduce the thickness of the material. As the structural strength of components. , 347 stainless steel rod heat treatment: solution treatment (℃) 980-1150 347 stainless steel rod through the fast-cooling solution treatment of mechanical properties of austenitic steel (GB/T4237-92) yield strength ≥ 205/MPa, tensile strength ≥ 520 / MPa, elongation ≥ 35%, hardness test: HBS ≤ 187, HRB ≤ 90, HV ≤ 200 347 stainless steel bar 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 resistance to corrosive media can be a high-alloy steel, stainless steel is a beautiful surface and good corrosion resistance, without After plated surface treatment, and the play inherent in the surface properties of stainless steel, used in a wide range of steel, often referred to as stainless steel. Representative of the performance of 13 ,18-8 chrome steel high alloy chrome-nickel steel. From the metallographic point of view, because the stainless steel contains chromium leaving the thin chromium film formed on the surface, the inner membrane to isolate and steel from corrosion-resistant invasive oxygen role. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% of chromium
