347 stainless steel
347 stainless steel is a brand of stainless steel produced according to American ASTM standard. The 347 stainless steel tube is equivalent to China's 0Cr18Ni11Nb stainless steel.
We can provide various sizes of 347 stainless steel tubes, plates, rolls, etc.
Introduction
Stainless Steel 347 has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. Alloy 347 is a columbium(niobium)/tantalum stabilized austenitic chromium-nickel stainless steel which was developed to provide an 18-8 type alloy with improved intergranular-corrosion resistance.
347 stainless steel has increased strength and no reduction in plasticity. Reduce the thickness of the material. It is used as structural strength component.
Chemical Composition (wt%) limits as specified in ASTM A240 and ASME SA240*.
