UNS C69100, a yellow metal copper-based alloy, is used extensively in the European oil and gas industry. A series of sour environmental tests was conducted at ambient temperature and at elevated temperature and pressure. The ambient temperature tests indicated high resistance to sulfide stress corrosion cracking (SSCC). Additionally, tests including free sulfur exhibited no evidence of cracking. The high temperature and pressure tests also showed no tendency for SSCC. The corrosion rate tests at ambient temperature indicated corrosion rates well below those of carbon steel tested in an identical environment. Hydrogen permeation measurements confirmed the corrosion rate measurements. This alloy should be considered for sour service use.
