Some of the properties of a 25 pct chromium duplex stainless steel, FERRALIUM /SUP R/ alloy 255,* as related to sour gas well applications are presented. Autoclave tests have demonstrated negligible corrosion rates in NaCl/sub -/, CO/sub 2//sup -/, and H/sub 2/S-containing environments to 200/sup 0/C (400/sup 0/F). The steel exhibited resistance to environmental embrittlement for a broad range of H/sub 2/S concentrations. At high H/sub 2/S concentrations stress corrosion cracking (SCC) occurs. Sigma phase formation is detrimental to SCC resistance. Heat treatments at temperatures of 1040/sup 0/C to 1150/sup 0/C (1900/sup 0/F to 2100/sup 0/F), which are above the sigma-phase formation temperatures, did not have a measurable effect on SCC as determined with plastically deformed two-point beam specimens.
