Well completion tools require BÖHLER steels and alloys with high strength and corrosion resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable oil and gas performance.
Well completion tools in the oil and gas industry, including packers, valves, and downhole components, operate in highly demanding environments characterized by high pressures, elevated temperatures, and aggressive media such as CO₂, H₂S, brines, and hydrocarbons. These conditions require materials with exceptional mechanical strength, corrosion resistance, and resistance to stress corrosion cracking and hydrogen embrittlement. In addition, components must perform reliably under cyclic loading and maintain sealing integrity and dimensional stability over long service periods in inaccessible downhole conditions.
BÖHLER high-performance steels and alloys are specifically engineered to meet these stringent requirements. Advanced quenched and tempered steels, corrosion-resistant stainless steels (austenitic, duplex, and precipitation-hardened), and high-alloy grades provide an optimized combination of toughness, strength, and resistance to aggressive environments. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and homogeneous microstructures, significantly improving fatigue life and operational reliability. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes. Comprehensive testing, including corrosion evaluation, pressure resistance, and non-destructive inspection, ensures compliance with oil
BÖHLERL718 API (UNS N07718) is a high-strength, corrosion-resistant nickel-chromium-iron-molybdenum material with excellent corrosion resistance, especially in H2S and CO2 environments. The alloy is age-hardenable due to the addition of niobium, titanium and aluminium. BÖHLER L718 API is recognised by the oil industry for its simple and cost-effective production in combination with good tensile, fatigue, creep and fracture strength and is used in a wide range of applications in this sector. BÖHLER L718 API has excellent weldability and is resistant to cracking after welding. The material can be used at high temperatures. BÖHLER L718 API is available in the NACE/API 6A CRA versions with a minimum yield strength of 120/140 ksi and also in the high-strength version with 150 ksi. All hardness grades are suitable for sour service and can be used for pressurising and pressure-controlling equipment in corrosive environments. Typical applications include packers, pumps, connectors and fasteners as well as gate valves, throttle spindles, pipework hangers and fire safe valves, but also a wide range of downhole and completion components, nuclear and surface applications.
