303 Stainless Steel Hex Bar
Stainless Steel Hexagon Bar 303 is a hexagonal-shaped 303 Stainless Steel Alloy Bar. 303 Stainless Steel Hex Bar is a chromium-nickel stainless steel with added sulfur or selenium and phosphorus to improve machinability and non-seizing properties. It is the freest machining of the chromium-nickel grades. When annealed, non-magnetic properties are produced.
303 is an “18-8” chrome-nickel stainless steel modified by the addition of selenium or sulphur and phosphorus to improve machinability and galling resistance. It is the most machinable of all the chrome-nickel grades and has good corrosion resistance.

APPLICATIONS
303 is used almost exclusively for parts requiring machining, grinding, or polishing, where good corrosion resistance is also required. It’s non-seizing and non-galling properties make it ideal for moving parts. Being an austenitic steel, it is useful where low magnetic permeability is desired. 303 has fairly good forming properties. Used for aircraft parts, as well as shafts, gears, valves, valve trims, all types of screw machine products, bolts, screws, and machine parts, as well as for architectural purposes. It is not recommended for vessels containing liquids or gases under high pressure
