347 stainless steel coil supplier from china
347 stainless steel coil is a grade of stainless steel produced in accordance with American ASTM standard. 347 stainless steel coil is equivalent to 0Cr18Ni11Nb in China.
347 stainless steel coil: chromium containing 18%, containing nickel 11%
347 stainless steel contains the tantalum and niobium, it is usually used for welding parts at high temperature.
347 stainless steel coil=0Cr18Ni11Nb, as it contains Nb, so the intergranular corrosion resistance is improved. It has good strength plasticity. It is used as a strength component for the structure.
347 stainless steel coil heat treatment: solid solution. Under 980-1150 degree, fast coldening.
Mechanical properties of 347 austenitic stainless steel coil treated by solid solution (GB/T4237-92):
The yield strength is greater than 205/MPa, the tensile strength is greater than 520/ MPa, the elongation is more than 35%, hardness test: HBS is less than 187, HRB is less than 90, HV is less than 200.
347 stainless steel coil chemical composition: C≤0.08%, Si≤1%, Mn ≤2%, P ≤0.035%, S ≤0.030%, Ni=9~13%, Cr=17.00~19.00%, Nb ≥5*C%
347 stainless steel coils is is a kind of stainless steel, which has beautiful surface and corrosion resistance.
