Material 431 is a rust- and acid-resistant, martensitic chromium
steel with nickel addition.
Stainless 431 is designed to provide improved corrosion resistance
and toughness in a quenchhardenable stainless steel.
Mechanical properties include excellent toughness (impact strength)
at relatively high hardness level.
It offers the best corrosion resistance of the conventional
martensitic stainless grades.
Stainless Type 431 has been used for highly stressed aircraft
components including fasteners, bomb
racks, bolting, pump shafts, valve stems, spinneret plate etc.
It should be considered for applications requiring the optimum
combination of corrosion resistance,
hardness and toughness from approximately -100 to 1200ºF (-73 to
650ºC).
