303 stainless steel round bar

The 303 stainless steel round bar has excellent machinability characteristics.

High Quality 303 stainless steel round bar

Corrosion-Resistant and Versatile: 303 Bar

Because of the inclusion of Sulfur in the steel composition, 303 Stainless has excellent machinability characteristics. Since Sulfur improves machining, it also negatively corrosion resistance and toughness to a minor extent. A lower corrosion resistance rating than type 304 is achieved using type 303 steel. Toughness is excellent, as it is with the other austenitic grades.

Machinability and other Processes

Although 303 round bar is not generally recommended to weld, it is still possible with some difficulty. After welding, the part should be annealed to re-dissolve any precipitated carbides. Meanwhile, its high machining rates can be achieved in the annealed condition when the hardness of the material is in the range of 200-240 Brinell.

Applications of 303 Stainless Steel Round Bar


It is undoubtedly a big help in many industries because of its incredible characteristics. Aircraft fittings, bolts, bushings, gears, nuts, and shafts are just a few of the many applications of 303 bar.

Buy 303 Stainless Steel Round Bar

303 round bar is a type of stainless steel, which is an alloy of chromium and nickel. It has high corrosion resistance and low magnetic permeability. This makes it suitable for corrosive environments like chlorine gas, hydrochloric acid, and salt water.

Not only that, 303 bar can be useful for applications that require high strength at elevated temperatures. 303 round bar is also an engineering material in food processing equipment because it does not react with food products such as meat or dairy. 

This stainless steel bar is often used in the automotive industry to make pistons because of its ability to withstand high temperatures without changing shape or corroding.
