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.

Číst víceBÖHLER L718AMS is a corrosion and heat resistant nickel alloy – precipitation hardenable – in the form of bars, forging and forging stock. High resistance to creep and stress-rupture up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C). High duty parts and components for oil & gas and CPI applications, components for automotive, gas turbines, aerospace engines, high-speed airframe parts such as disks, buckets, spacers and high temperature bolts and fasteners.
Číst víceBÖHLERL718 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.
Číst víceBÖHLER L725 (UNS N07725) is an age-hardenable nickel-chromium-molybdenum-niobium alloy with comparable corrosion resistance to Alloy 625. The strength of Bohler L725 in the age-hardened condition is approximately twice that of annealed Alloy 625 and comparable to Alloy 718. The high nickel and chromium content provides corrosion resistance in reducing and oxidizing environments, while the molybdenum content increases resistance to reducing media and offers high resistance to pitting and crevice corrosion. The combination of elements makes the alloy resistant to hydrogen embrittlement and stress corrosion cracking. BÖHLER L725 is also approved according to NACE MR0175 for use under sour gas conditions. The alloy was originally developed for oilfield applications such as wellheads and well completions, safety valves and other downhole components where it resists the effects of hydrogen sulfide, chlorides and carbon dioxide. The alloy is also attractive for pumps and propeller shafts as well as for high-strength fasteners and hydraulic couplings in marine applications subject to corrosion, pitting and crevice attack in seawater.
Číst víceBÖHLER L925 (UNS N09925) is an age-hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, titanium and aluminium and is designed for high strength and excellent corrosion resistance. The nickel content provides protection against chloride-ion stress corrosion cracking and, in combination with molybdenum and copper, also offers excellent resistance to reducing chemicals. Molybdenum aids resistance to pitting and crevice corrosion. The chromium content of the alloy ensures resistance in oxidising environments. The alloy exhibits a high degree of corrosion resistance in H2S and CO2 environments and is particularly suitable for sour (H2S-containing) crude oil, natural gas, sulphuric acid, phosphoric acid and seawater. BÖHLER L925 offers high strength and maintains this strength even at high temperatures. BÖHLER L925 meets the requirements of NACE MR0175 and API 6A CRA for acidic applications and can be used for pressure-maintaining and pressure-controlling equipment in corrosive environments. Typical applications include packers, safety valves, pumps, hangers, connectors, fasteners and numerous downhole and surface applications.
Číst víceBÖHLER P501 is a highly corrosion-resistant, nitrogen-strengthened Cr-Ni-Mo-N steel that is characterised by its resistance to corrosion in seawater and very good resistance to intergranular corrosion and stress corrosion cracking. Due to the alloy design, the yield strength is significantly higher than that of a comparable Cr-Ni-Mo stainless steels and a stable austenitic microstructure is achieved, so that the steel remains non-magnetisable even after cold forming and has the lowest magnetic permeability. In addition to its original application as a hull and structure for submarines, BÖHLER P501 is also used for magnetic shielding and components in the oil and gas industry, for example.
Číst víceBÖHLER P511 is a weldable, non-magnetic, austenitic steel with resistance to seawater and intergranular corrosion. This austenitic, stainless Cr-Ni-Mn-Mo-N steel has higher corrosion resistance than Cr-Ni-Mo grades 316, 316L, 317 and 317L and approximately twice the yield strength at room temperature. In addition, BÖHLER P511 has very good mechanical properties at both high and low temperatures. Unlike many austenitic stainless steels, it does not become magnetic when cold-formed or cooled to sub-zero temperatures. Thanks to its excellent notched impact strength at -196 °C (-320 °F), BÖHLER P511 is particularly suitable for low-temperature applications. Typical applications are found in the oil and gas, chemical, fertilizer, paper, textile, food and marine industries for components requiring a combination of excellent corrosion resistance and high strength, e.g. pumps, valves and fittings, fasteners, cables, chains, ship fittings, boat and valve shafts, heat exchanger parts and springs.
Číst víceBÖHLER T200 covers a corrosion and heat resistant steel in the form of bars, wire, forgings and forging stock. It is an austenitic, precipitation hardenable, iron-nickel-chromium-molydenum-titanium steel of ESR quality. Alloying elements of aluminium and titanium allow this material to undergo precipitation hardening (ageing) through the formation of intermetallic phases. The addition of molybdenum increases the mechanical properties and resistance to creep at high temperatures. These products are typically used for parts in the oil and gas industry requiring moderate strength up to 704 °C (1300 °F) and oxidation resistance up to 816 °C (1500 °F), but their use is not limited to such applications.
