303 is an austenitic stainless steel, slightly magnetic and very corrosion resistant. 303 is a free-machining stainless steel. The free-machining characteristics are provided by adding sulphur and/or selenium. Using 303 stainless steel can be more cost effective than using other stainless steels since 303 takes less time to machine, machine tool bits will last longer. 303 is similar to 304 grade (A2 or 18/8) but is easier to machine.
Maximum Brinell Hardness (HB) is 262.
The main component of the steel is Fe (Iron) with the addition of the elements shown in the following chart
Max. % Chemical Composition | |||||||
C | Si | Mn | P | S | Cr | Mo | Ni |
0.1 | 1.0 | 2.0 | 0.2 | 0.15 | 17.0 to 19.0 | - | 8.0 to 10.0 |
For better corrosion resistance but lower machinability see 304 Grade
For higher resistance to pitting and crevice corrosion in chloride environments but lower machinability see 316 Grade
For better machinability but lower corrosion resistance, or if hardening by heat treatment is required see 416 Grade
