  "term": "Corrosion-resistant alloy (CRA)",
  "field": "Oil and gas",
  "definition": "A metallic material, such as stainless steel or nickel-based alloys, specifically engineered to withstand corrosive environments encountered in oil and gas production. These alloys contain elements like chromium, molybdenum, and nickel to form a passive layer that resists chemical degradation. CRAs are selected for downhole tubulars, valves, and other components exposed to sour gas or high-chloride brines.",
