 For instance, many 431 stainless steel round bar suppliers note that the alloy has excellent resistance to corrosion, in addition to superior torque strength. Other properties of the ASTM A276 AISI 431 Stainless Steel Round Bars include its high toughness and high tensile strength properties. A combination of these properties makes the Stainless Steel 431 Hexagon Bar ideal for the manufacture of fasteners such as bolt and shaft applications.

however, the 431 Stainless Steel Black Bar is an alloy that cannot be cold-worked. This is because the alloy has a high yield strength. Hence the Stainless Steel 431 Square Bar is well suited for operations such as deep drawing, spinning, bending or cold heading. Fabrication of 431 Martensitic Stainless Steel Bar is generally carried out using techniques that permit treatments like hardening and tempering and poor weldability. The corrosion resistance properties of grade 431 Stainless Cold Finish Round Bar is much lower in comparison to that of austenitic grades.

The operations of grade 1.4057 stainless steel equivalent are often limited by their loss of tensile strength at elevated temperatures due to over-tempering. Whereas the 431 Steel Hollow Bars lose their ductile properties at cryogenic temperatures.
