Drilling tools in oil and gas industry require BÖHLER steels with high strength, wear, and corrosion resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable oil and gas performance.
Drilling tools and components in the oil and gas industry operate under some of the most extreme conditions encountered in industrial applications, including high pressures, elevated temperatures, abrasive rock formations, and corrosive environments containing drilling fluids, salts, and hydrocarbons. Material requirements are therefore highly demanding, focusing on exceptional strength, fatigue resistance, impact toughness, and resistance to abrasive wear and stress corrosion cracking. In addition, materials must provide reliable performance under dynamic loading and maintain dimensional stability during long drilling cycles.
BÖHLER high-performance steels and alloys are specifically engineered to meet these rigorous requirements. Advanced quenched and tempered steels, wear-resistant tool steels, and corrosion-resistant alloy grades offer an optimized balance of hardness, toughness, and durability. Produced using advanced melting and refining technologies, BÖHLER materials ensure superior cleanliness, low inclusion content, and homogeneous microstructures, significantly reducing the risk of crack initiation and extending service life. Key quality features include strict control of chemical composition, certified traceability, and precisely defined heat treatment processes tailored to drilling applications. Comprehensive testing, including fatigue, impact resistance, wear performance, and non-destructive inspection, ensures consistent quality. BÖHLER materials enable reliable, efficient, and long-lasting drilling tool performance in demanding oil and gas environments.
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.
