303 Stainless Steel
Grease Fittings
303 is a free-machining grade of 304 stainless steel that contains added sulphur. The addition of the sulphur increases the machinability. Commonly referred to as A2, V2A or 1.4305 in Europe.
Its composition contains at minimum 17% Chromium, 8% nickel, and 0.15% Sulphur. The small addition of sulphur slightly reduces corrosion resistance but increases machineability which is why you will find its use in fasteners, bushings, bearings, and other smaller components.
