ASTM A182 F347 Stainless Steel Weld-Neck Flange , RF / RTJ Face For High-temperature Application



Overview


ASTM A182 F347 Flange (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100). It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation ASTM A182 F347H Flanges (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C). In most instances, the carbon content of the plate enables dual certification.


Corrosion Resistance

SS347 exhibits good general corrosion resistance that is comparable to 304. It was developed for use in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C) where un-stabilized alloys such as 304 are subject to intergranular attack. In this temperature range, the overall corrosion resistance of SS347 stainless steel plate is superior to Alloy 321 stainless steel plate. SS347 also performs somewhat better than Alloy 321 in strongly oxidizing environments up to 1500°F (816°C). The alloy can be used in nitric solutions, most diluted organic acids at moderate temperatures and in pure phosphoric acid at lower temperatures and up to 10% diluted solutions at elevated temperatures. SS347 stainless steel plate resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be utilized in chloride or fluoride free caustic solutions at moderate temperatures. SS347 stainless steel plate does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid.
