Alloy SS 347/347H description-
Alloy 347 is the austenitic stainless steel columbium stabilized alloy with general corrosion resistance and also very good resistance at the strong oxidizing conditions. It is having very good resistance ability against intergranular corrosion after it gets exposed to the temperature ranging 427 Deg C to 816 Deg C at the chromium carbide precipitation. This alloy is having very good creep strength and oxidation resistance. Also, the alloy possesses very good low-temperature toughness. Alloy 347H is the high carbon version of the alloy 347. This alloy is developed in order to enhance the creep resistance and for the high strength at the temperature that ranges above 100 Deg F. In many cases, the carbon content is enabling dual certifications.
