Mechanical properties are as under. Tensile strength is from 500 to 750 Mpa in some technical sources. Hardness in HB as specified in technical sources is from 48 to 230. Yield strength (Proof stress) is from 190 Mpa in some technical sources. Elongation is 35% in the standard.
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. This alloy offers good corrosion resistance and oxidation resistance in mild STAINLESS STEELS FOR MACHINING - Nickel InstituteReference to stainless steel is often made in the singular sense as if it were one material. Actually there are approximately 150 separate and distinct compositions, each one formulated to serve specific end-use and/or manufacturing requirements.

That said, grade 303 steel is, for the most part, unweldable. Type 304 stainless doesnt harden with heat treatment and is not a free-cutting material, making it less than ideal for use in machining.
Stainless Steel 303 Properties - Anand SteelsStainless Steel 303. Stainless Steel 303 is a free machining non-magnetic austenitic alloy specially designed for improved machinability while maintaining good mechanical and corrosion resistant properties. AISI 303 is cannot be hardened by heat treatment, but tensile and hardness can be increased by cold working with subsequent reduction in ductility.The sulfur addition which is responsible for the improved machining and galling characteristics of Grade 303
Alloy 303 (UNS S30300) is an austenitic stainless steel developed for applications requiring extensive machining operations. The alloy has a sulfur addition which assists in breaking up turnings while reducing drag on the cutting tool when compared to the machining characteristics of the conventional 18-8 stainless steels.
