303Se-cold-rolled-stainless-steel-coil is very close in chemical and physical properties to Type 303. It has some ductility and comes with good strength. 303Se-cold-rolled-stainless-steel-coil is a great choice for machining, but it is also not very simple to weld either. Therefore, just like the 303 types you can mod it or create different machinery shapes using this type of stainless steel.

303Se-cold-rolled-stainless-steel-coil is an austenitic steel that contains chromium and nickel. It is also non-hardenable. 303 Stainless Steel with the addition of Selenium improves machinability and allows for less galling. 303Se-cold-rolled-stainless-steel-coil is non-magnetic in the annealed condition, however, may show minor magnetic properties after being cold worked.
