Alloy 303 is a non-magnetic, austenitic stainless steel that is not hardenable by heat treatment. It is the free machining modification of the basic 18% chromium / 8% nickel stainless steel. Alloy 303 was specially designed to exhibit improved machinability while maintaining good mechanical and corrosion-resistant properties Due to the presence of sulfur in the steel composition, Alloy 303 is the most readily machineable austenitic stainless steel; however, the sulfur addition does lower Alloy 303’s corrosion resistance to below that of Alloy 304. Like other austenitic grades, Alloy 303 demonstrates excellent toughness, although the sulfur does reduce this a little as well. Ni - 9.00, Cr-18.00, Fe-Balance, Si -1.00, Mn-2.00, C - 0.120,  P-0.040, S - 0.030 Key Properties These properties are specified for the long product (bar) in ASTM A582. Similar but not necessarily identical properties are specified for other products such as wire and forgings in their r

304 stainless steel grade: Ni - 9.25, Cr - 19.0, Fe - Balance, Si - 1.00, Mn - 2.00, C - 0.080, P - 0.045, S - 0.030 Stainless Steel 304 Chemical Properties: It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Stainless steel 304 is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. Type 304L is the low carbon version of Stainless steel 304 . It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as “dual certified” material that meets the criteria for both 304 and 304L. 304H, a high carbon content variant, is also available for use at high temperatures.
