303 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190.
303 Stainless Steel Bar - 303 - National Specialty Alloys303 Stainless Steel Bar UNS S30300 (Grade 303) 303 stainless steel bar, also known as UNS S30300 and Grade 303, is considered a free machining stainless steel. 303 stainless steels corrosion resistance and great machinability make it one of the most popular free machining stainless steels available. It is used in a wide variety of 
303 stainless steel is a free-machining, austenitic, nickel stainless steel that is used primarily for parts requiring machining, grinding or polishing. The sulfur addition present in 303 SS assists in breaking up turnings which reduces drag on cutting tools.
ATI 303ATI 303 alloy is a free-machining stainless steel specifically designed to exhibit improved machinability. It is a non-magnetic austenitic stainless steel which is not hardenable by heat treatment. It is the free-machining modification of the basic 18% chromium 8% nickel stainless steel.
China 303 Stainless Steel Bars Manufacturers, Suppliers 1.4305 Specifications Stainless steel type 1.4305, popularly known as grade 303 is the most readily machinable austenitic grade stainless steel. This is due to urge presence of Sulphur in the composition. The downside to this improved machinability is the sulphur decreases corrosion resistance
May 18, 2005 · Grade 303 stainless steel has good resistance to oxidation when intermittently exposed to temperature up to 760°C temperatures. It also has good oxidation resistance in continuous service to 870°C. This, however, is not recommended as 303 is sensitive to carbide precipitation with continuous use at 425-860°C.

1.4305 (303) Bar Stainless steel type 1.4305 is popularly known as grade 303 stainless steel. Grade 303 is the most readily machineable of all the austenitic grades of stainless steel. The machineable nature of grade 303 is due to the presence of Sulphur in the steel composition.
The Battle of Stainless:303/304 vs. 316 MISUMI BlogMay 31, 2019 · While 303 stainless steel still has strong corrosion resistance, for an added boost, 304 stainless steel is recommended. 304 Stainless Steel 304 stainless steel contains a minimum of 18% chromium and 8% nickel which gives its alternate name 18/8 stainless steel. 304 stainless steel contains chromium-nickel content and low carbon.Stainless Steel Grade 303 / 1 - Farnell element14Stainless steel 303 also corresponds to the following standard designations and specifications:Euronorm UNS BS En Grade 1.4305 S30300 303S31 58M 303 Corrosion Resistance Sulphur additions to the composition act as initiation sites for pitting corrosion. This decreases the corrosion resistance of 303 stainless steel to less than that for 304.
