Alloy 925

Alloy 925 offers high strength and excellent corrosion resistance in H2S and CO2 environments. 925 can be used in high temperatures as it has high temp de-rating factors and maintains strength at elevated temperatures. 925 meets the requirements of NACE MR0175 and API 6ACRA for sour service applications and is suitable for sour service and can be used for pressure containing and pressure controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, and fasteners.
