AISI 303/Grade 303 Stainless Steel Bar
AISI 303 or the UNS S30300 stainless steel bar, is free machining steel. With impressive corrosion resistance and great machinability. Extensively used free machining stainless steel components and products .
Grade 303 is not responsive to heat treatment, Not available for welding, Its impressive toughness is greater than normal 300 series stainless.
AISI 303/Grade 303 Application
CNC Machining Components
Precision Screw Machining
Bushings
Aircraft Fittings
Gears
Shafts
Nut and Bolt
Screws
