304 is the original “18-8” stainless. It is produced in greater quantity than any other austenitic stainless steel. 304 provides useful resistance to corrosion in many environments ranging from moderately reducing to moderately oxidizing. Through the controlled addition of nitrogen, it is common for 304L to meet the mechanical properties of 304. As a result, most products are dual certified as 304/304L.

Bar also available in PRODEC® enhanced machining grade.
