Product Description

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.

Property Features

Soft martensitic chromium stainless steel with 4% nickel addition. Good properties at subzero temperature. The alternative to conventionally melted BÖHLER N400 EXTRA is BÖHLER N400 ISOEXTRA produced by the Electroslag remelting procedure (ESR).
