Stainless Plate 303 is one of the easiest stainless steel alloys to machine, grind and polish. Toughness and corrosion resistance are slightly lower than most other stainless steels as a result. It is typically used in aircraft applications, machine parts, pump and valve parts, architectural applications, nuts, and bolts.

This plate is made from stainless steel alloy 303, known for its excellent machinability and corrosion resistance, making it ideal for fasteners, gears, shafts, and other parts requiring frequent machining.

Yes, alloy 303 is specifically designed for superior machinability, making it easy to cut, drill, and machine to your required dimensions.

Alloy 303 offers good corrosion resistance in mild environments, making it suitable for parts used indoors or in moderately corrosive settings but is not recommended for marine or highly corrosive environments.

This plate is annealed and has an HRAP (Hot Rolled, Annealed, and Pickled) finish, providing good workability and a clean surface for further processing.
