Alpha Overseas(AOS) manufactures and exports these SS 347 Compression Tube Fittings, which is stabilized by the addition of columbium and tantalum. These Alloy 347 Ferrule Tube Fittings is stabilized by the additions of chromium and tantalum and offers higher creep and stress rupture properties than alloy 304 and 304L which may also be used for exposures where sensitization and intergranualr corrosion are of concern. In addition, our Grade 347 Double Ferrule Tube Fittings form another group known as precipitation-hardened steels, which are a combination of martensitic and austenitic steels. These SS 347 Tube Fittings can be used in applications requiring repeated heating in the range of 800 Degree F and 1650 Degree F (427 Degree C - 899 Degree C). Our AISI 347 Compression Fittings are stabilized by the addition of columbium and tantalum, which has restricted cobalt and tantalum content for nuclear applications. These 347 Stainless Steel Compression Tube Fittings is stabilized with columbium, which is further preferable for aqueous and low temperature environments due to its good resistance to intergranular attack.
Our Stainless Steel UNS S34700 Compression Tube Fittings also has excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 Degree F to 1500 Degree F.
These Stainless Steel Din 1.4550 Tube Fittings 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.
