This kind of 347h seamless stainless steel tube has been added with certain anti-oxidation treatment during the production process. There is a layer of rare metal plating on the surface of this kind of seamless steel tube, which is a good way to isolate the tube from the air, thus reducing the possibility of rusting the tube. Under the conditions of chromium carbide precipitation, it still maintains good corrosion resistance. Moreover, The titanium in it can maintain excellent stability even in the case of chromium carbide formation.
Excellent high temperature strength and plasticity
Excellent oxidation resistance and corrosion resistance
Uniform chemical composition
Excellent processing performance and welding performance
High dimensional accuracy and surface quality
Widely used as heat exchanger tubes for large boiler superheaters, reheaters, steam pipes, petrochemicals.
