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.

Číst víceBÖHLER L004 belongs to the group of highly corrosion-resistant nickel-chromium-molybdenum alloys with very low carbon, iron and silicon content and has good corrosion resistance, even at elevated temperatures. The combination of chromium with a high molybdenum content gives BÖHLER L004 exceptional resistance to a wide range of chemical media: e.g. contaminated, reducing mineral acids and good resistance under reducing and oxidizing conditions, e.g. hot, contaminated media such as sulphuric acid, nitric acid, dry chlorine, formic acid, acetic acid, solvents, chlorine and chloride-containing media. BÖHLER L004 exhibits a significantly reduced tendency to form precipitates in the temperature range between 650 and 1,040 °C due to the alloy composition. This improves resistance to intergranular corrosion. Due to the high nickel content, the material is practically insensitive to chloride-induced stress corrosion cracking even in hot chloride solutions. Due to its excellent thermal stability, the alloy can be welded without any problems and is generally used in the welded condition. Suitable for pressure vessels with wall temperatures from-196°C to 400°C.
Číst víceBÖHLER L022 belongs to the group of highly corrosion-resistant nickel-chromium-molybdenum-tungsten alloys with extremely low carbon and silicon contents. Good resistance to wet media, e.g. sulphuric acid, nitric acid, acid mixtures of sulphuric acid and oxidising acids with chloride ions. Recommended for use in the presence of strong oxidising agents such as iron(III) and copper(II) chlorides, chlorine gas, formic acid, acetic acid, seawater and other salt solutions. High resistance to crevice, pitting and stress corrosion cracking at elevated temperatures under oxidising and reducing conditions. Used in environmental engineering, e.g. in agitators, heat exchangers and spray systems in flue gas cleaning plants and in waste water treatment plants, evaporation plants in chemical process engineering, in chlorine bleaching plants and plants for the production of chlorine gas and hydrogen chloride, e.g. butterfly valves, gate valves, pipelines and centrifuges. Suitable for pressurised containers with wall temperatures from-196°C to 400°C. Due to its good thermal stability, BÖHLER L022 can generally be used in the welded condition without subsequent heat treatment.
Číst víceBÖHLER L276 is a nickel-chromium-molybdenum alloy with universal corrosion resistance unmatched by any other alloy. It has outstanding resistance to a wide variety of chemical process environments including ferric and cupric chlorides, hot contaminated mineral acids, solvents, chlorine and chlorine contaminated (both organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, sea water and brine solutions and hypochlorite and chlorine dioxide solutions. BÖHLER L276 also resists formation of grain boundary precipitates in the weld heat affected zone making it useful for most chemical processes in the as-welded condition. BÖHLER L276 has excellent resistance to pitting and stress corrosion cracking. Some typical applications of BÖHLER L276 include equipment components in chemical and petrochemical organic chloride processes and processes utilizing halide or acid catalysts.
