Pumps and high-pressure components require BÖHLER steels and alloys with high strength and corrosion resistance. Key quality features include ultra-clean materials, full traceability, controlled heat treatment, and rigorous testing for reliable oil & gas and CPI performance.
Pumps and high-pressure components in the oil & gas and Chemical Process Industry (CPI) are exposed to extreme operating conditions, including very high pressures, temperature variations, and aggressive media such as sour gases, hydrocarbons, and chemical process fluids. These demanding environments require materials with outstanding mechanical strength, excellent corrosion resistance, and resistance to stress corrosion cracking and hydrogen embrittlement. In addition, components must provide high fatigue resistance, dimensional stability, and reliable sealing performance over long service intervals under cyclic loading and pressure fluctuations.
BÖHLER high-performance steels and alloys are specifically engineered to meet these challenges. Advanced quenched and tempered steels, stainless steels (austenitic, duplex, and precipitation-hardened), and high-alloy nickel-based materials offer an optimized balance of strength, toughness, and resistance to corrosive and high-pressure environments. Produced using advanced melting and refining technologies, BÖHLER materials ensure exceptional cleanliness, low inclusion content, and homogeneous microstructures, significantly improving fatigue life and operational reliability. Key quality features include strict control of chemical composition, certified traceability, and precisely controlled heat treatment processes. Comprehensive testing, including pressure resistance, corrosion evaluation, and non-destructive inspection, ensures compliance with stringent oil & gas and CPI standards. BÖHLER materials enable safe, efficient, and long-lasting pump and high-pressure component solutions.

Číst víceBÖHLER N400 is a stainless soft martensitic Cr steel with 4% nickel with molybdenum addition and medium corrosion resistance in media with only a low chloride content. To achieve the best possible corrosion resistance with BÖHLER N400, it is essential to polish the surfaces concerned. Good mechanical properties in the quenched and tempered condition. This makes this material very suitable for use in turbine and power plant construction. Very good low-temperature properties. Recommended temperature of use: – 60 to 350°C. Use for valves, pumps, compressors, centrifuges, hydroelectric machines, turbines, reactor technology, shipbuilding, chemicals. Special heat treatment to max. 23 HRC is required for sour gas enviroment in petroleum engineering.
Číst víceBÖHLER N685 is a corrosion-resistant steel with molybdenium and vanadium additions in the form of bars, wire, forgings, and forging stock. These products have been used typically for parts in engineering and medical applications requiring hardness up to 58 HRC and resistance to wear, corrosion, and oxidation, but usage is not limited to such applications.
Číst víceBÖHLER N700 is a corrosion-resistant steel in the form of bars, wire and forgings in the solution-annealed condition. It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further increases in strength can be achieved by cold forming and subsequent precipitation hardening. These products are typically used for parts that require higher corrosion resistance than the usual 13% or 17% chromium steels and high strength up to 316 °C. However, their use is not limited to such applications. Remelting processes are used to improve steel purity and homogeneity. (ESR, PESR, VAR) Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. For applications such as bolting where stress corrosion cracking is possible, the product should be aged for at least 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552 °C. Typical applications for reactor construction and highly stressed pump parts, springs and ship shafts.
Číst víceBÖHLER N701 is a corrosion-resistant steel available in the form of bars, wire, and forgings in the solution-annealed condition. It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further strength enhancements can be achieved through cold working and subsequent precipitation hardening. These products are typically used for parts that require higher corrosion resistance than conventional 13% or 17% chromium steels and high strength up to 316°C. However, their use is not limited to such applications. The vacuum melting process is used to improve steel purity and homogeneity. Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. Typical applications include reactor construction, highly stressed pump parts, springs, ship shafts, plastic injection molds and compression molds, and medical instruments.
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.
