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.

The BÖHLER L718 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.

BÖHLER 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.

The 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.

BÖHLER 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.

BÖHLER N404 is a stainless, soft martensitic Cr steel with 5% nickel and molybdenum addition with higher corrosion resistance than that of stainless steels of type 1.4313. The molybdenum addition also permits limited use in the maritime sector. BÖHLER N404 is particularly insensitive to intergranular corrosion and very resistant to fatigue and stress corrosion cracking and offers good mechanical properties in the quenched and tempered condition. This makes this material very suitable for use in the oil and gas sector, e.g. for fittings, pumps, compressors, centrifuges, hydropower machinery, reactor technology, shipbuilding, chemicals, petroleum technology, aviation and refrigeration technology. Very good low-temperature properties. Recommended application temperature from – 60 to 350°C. Special heat treatment to max. 23 HRC is required for sour gas stress in petroleum technology. In order to achieve the best possible corrosion resistance, the relevant surfaces must be polished.

BÖHLER N425 (UNS S41427) – Super 13Cr – is a martensitic stainless steel with a nickel content of approx. 5% and 2% molybdenum, with excellent corrosion resistance in a CO2 environment and at low concentrations of chlorides and H2S and is more resistant than comparable 13%Cr steels. The steel is particularly resistant to intergranular corrosion and stress corrosion cracking, is easy to weld and offers good mechanical properties in the quenched and tempered condition even at low temperatures. Recommended application temperature from – 60 to 350°C. The material is specially tested for toughness and behavior under sour gas load. In order to achieve the best possible corrosion resistance, it is essential to polish the relevant surfaces. BÖHLER N425 is available with a minimum yield strength of 95 ksi and maximum hardness of 29 HRC, making it suitable for limited NACE oxygen applications and also available as a 110 ksi version for standard and CO2 applications. This material is used in downhole completion tools for components such as packers, safety valves and other applications.

Components featuring elevated high-temperature strength for use in thermal engines and power plants, such as turbine blades, turbine discs, screws, bolts, pins and shafts.
