431 Stainless Steel has been designed to improved corrosion
resistance and toughness properties than other 400 stainless grades
especially in a quench-hardenable stainless. 431 would work well in
marine environments as well as in aerospace applications such as
aircraft fasteners and fittings. This alloy has great impact
strength at a high hardness level.
Out of all the martensitic grades of stainless steel 431 has the
best corrosion resistance. Some other applications include: bomb
racks, bolts, pump shafts, valve stems and aircraft fasteners. Only
the age hardenable martensitic stainless grades could achieve
greater resistance to corrosion. 431 is available in round bar,
strip and wire.

ASTM A276 | This specification encompasses cold-finished or hot-finished bars,
including rounds, squares, and hexagons, and hot-rolled or extruded
shapes, such as angles, tees, and channels in the more commonly
used types of stainless steels. |
ASTM A479 | This specification includes cold and hot finished stainless steel
bars, including rounds, squares, and hexagons, and hot-rolled or
extruded shapes such as angles, tees, and channels. |
ASTM A484 | This specification includes wrought stainless steel bars, shapes,
forgings, and billets or other semi-finished materials, except
wire, for forging. The materials are available in four types of
conditions. |
ASTM A582 | This specification includes cold or hot finished bars, which are
suitable for machining processes. This specification includes
rounds, squares, and hexagons, from common types of stainless
free-machining steels. |
ASTM B473 | This specification includes nickel alloy bar & wire, which can be
produced in a solution-annealed condition, stabilized-annealed
condition, or annealed |
