416 stainless steel round bar is a type of martensitic stainless steel that contains 12-14% chromium and a minimum of 0.15% sulfur. It is a high-strength material that offers good corrosion resistance, especially in mild environments.
Chemical Compositions (in %):
C Max | Mn Max | P Max | S Max | Si Max | Cr | Ni | Mo | Other Element |

416 ss round bar is commonly used in applications such as pump shafts, valve components, and motor shafts that require good strength and corrosion resistance. It is also used in manufacturing of nuts and bolts, gears, and fasteners.
The sulfur content in 416 stainless steel round bar improves its machinability, making it easier to machine than other stainless steels. However, it also reduces its weldability and ductility, which can limit its use in certain applications. The chromium content provides good corrosion resistance, while the carbon content improves its hardness and wear resistance.
416 ss 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 special techniques and tools may be required due to its sulfur content.
