431 stainless steel round bar is commonly used in applications such as shafts, valves, pumps, and marine equipment that require high strength, good corrosion resistance, and toughness. It is also used in the food processing and chemical industries, as well as in manufacturing of gears, bearings, and fasteners.
Chemical Composition (in %):
C Max | Mn Max | P Max | S Max | Si Max | Cr | Ni | Mo | Other Element |
0.20 | 1.00 | 0.04 | 0.03 | 1.0 | 15.0/17.0 | 1.25/2.5 | --- | --- |
The addition of nickel in 431 stainless steel round bar improves its toughness and ductility, making it more resistant to cracking and deformation under stress. The high carbon content in the material provides good hardness and wear resistance, while the chromium content improves its corrosion resistance.
431 stainless steel round bar can be hardened by heat treatment, such as quenching and tempering, to improve its mechanical properties. It can also be machined, welded, and polished, although it may require special techniques and tools due to its high hardness.
Overall, 431 stainless steel round bar is a high-performance material that offers good strength, toughness, and corrosion resistance, making it suitable for a wide range of industrial and commercial applications.
