Polythionic Stress Cracking

Normal 304 stainless steel becomes subject to polythionic stress corrosion cracking because it sensitizes after welding and/or long-term exposure under high-temperature service. To avoid sensitization, stabilized austenitic stainless steel such as Type 321 or 347 may be selected. [Pg.75]

Though nickel alloys are more resistant to chloride and caustic SCC than stainless steels, they are equally susceptible to cracking in polythionic acid (PTA) when in the sensitized condition. See ASTM G 35, Practice for Determining the Susceptibility of Stainless Steels and Related Nickel-Chromium-Iron Alloys to Stress Corrosion Cracking in Polythioiuc Acids, for test details. [Pg.583]

The 300 series offers excellent corrosion protection. Type 430 has good resistance to corrosion, but Type 410 provides corrosion protection only in mild environments. All stainless steels suffer from pitting corrosion in the presence of chlorides. The 300 series also is subject to stress-corrosion cracking by chlorides and polythionic acids. [Pg.203]

SOx, hot salt resistance, practical immunity to chloride ion and to polythionic acid stress corrosion cracking, good resistance to sulfuric acid, and excellent oxidation and carburization resistance at elevated temperatures. [Pg.277]

These alloys represent another version of Ni-Cr-Fe alloys and contain 30-44% of nickel. Alloy 800 of this series has been extensively used in heat exchangers in the petrochemical industry, because of its excellent resistance to stress corrosion cracking in chloride environments and cracking in polythionic acid. It offers an excellent resistance to creep and rupture. They are used for high environments where resistance to oxidation and corrosion is required. Incoloy 825 has proved highly successfiil in applications in H2SO4, HCl, phosphoric acid and clean and polluted seawater. [Pg.534]
