CPI components (LNG, urea) require BÖHLER steels and alloys with excellent corrosion resistance and toughness across extreme temperatures. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing.
Components for the Chemical Process Industry (CPI), including LNG and urea production systems, are exposed to highly aggressive environments characterized by extreme pressures, temperature gradients, and corrosive media such as CO₂, ammonia, chlorides, and cryogenic fluids. Material requirements are therefore exceptionally stringent, focusing on superior corrosion and stress corrosion cracking resistance, high toughness at both elevated and cryogenic temperatures, and long-term microstructural stability under continuous operation. Reliable performance under combined mechanical and chemical loading is essential to ensure plant safety, efficiency, and regulatory compliance.
BÖHLER high-performance steels and alloys are specifically engineered to meet these demanding CPI requirements. Advanced austenitic, duplex, and precipitation-hardened stainless steels, as well as high-alloy and nickel-based materials, provide optimized resistance to corrosion, embrittlement, and thermal degradation. Produced using advanced melting and refining technologies, BÖHLER materials guarantee exceptional cleanliness, low inclusion levels, and homogeneous microstructures, ensuring predictable and reliable performance. Key quality features include strict control of chemical composition, certified traceability, and validated heat treatment processes tailored to application needs. Comprehensive testing, including corrosion resistance, mechanical verification, and non-destructive inspection, ensures compliance with stringent industry standards. BÖHLER materials enable safe, efficient, and long-lasting operation of critical CPI components.
BÖHLER L625 AMPO is a non-magnetic, corrosion and scale-resistant nickel-base alloy. High toughness and strength from the lowest temperatures up to 1000 °C. Good printability.
Read MoreBÖHLERL718 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.
Read MoreThe BÖHLER L718 API AMPO is a hardenable nickel-base super alloy. This high heat-resistant material shows good strength properties at elevated temperatures up to 750 ° C, as well as excellent creep resistance up to 700 ° C. In addition, it shows excellent corrosion resistance and good printability. Essentially, the same properties can be achieved with printed components made from this powder as with bar material.
