Chemical plant components (LNG, FGD, urea, LDPE) require BÖHLER steels and alloys with excellent corrosion resistance and stability. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing.
Components for chemical plants, including systems for LNG, flue gas desulfurization (FGD), urea production, and LDPE processing, operate under extremely aggressive environments involving high pressures, temperature extremes, and exposure to corrosive media such as acids, chlorides, and reactive gases. Material requirements are therefore highly demanding, focusing on outstanding corrosion resistance, resistance to stress corrosion cracking, high-temperature strength, and long-term microstructural stability. In addition, materials must ensure reliable performance under combined chemical and mechanical loading while meeting strict safety and regulatory standards.
BÖHLER high-performance steels and alloys are specifically engineered to meet these critical challenges. Advanced stainless steels, including austenitic, duplex, and precipitation-hardened grades, as well as highly alloyed nickel-based materials, provide optimized resistance to corrosion, oxidation, and thermal degradation. Produced using advanced melting and refining technologies, BÖHLER materials offer superior cleanliness, low inclusion levels, and homogeneous microstructures, ensuring predictable performance and extended service life. Key quality features include strict chemical composition control, certified traceability, and validated heat treatment processes. Comprehensive corrosion testing, mechanical verification, and non-destructive inspection ensure compliance with demanding industry standards. BÖHLER materials enable safe, efficient, and durable operation of critical chemical plant components.
BÖHLER L625 is a non-magnetizable corrosion and heat resistant nickel alloy in the form of bars, forgings and semi-finished products up to max 254 mm diameter/ cross-section and oxidation resistant up to 1093°C. Best fatigue strength and resistance to stress corrosion cracking when exposed to chloride containing media. Good weldability.
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 MoreBÖHLER N700 AMPO (17-4 PH) is a precipitation hardening nickel martensitic steel. Thanks to its alloying system, this material has excellent corrosion resistance. Can be printed very easily without additional heating of the platform or chamber and, after solution annealing and aging, hardens up to approx. 40 HRC.
