ASTM A240 Type 304L represents an austenitic stainless steel modified to have a controlled carbon content, which improves strength and durability. It is documented and known both as 304L and 304L, and it meets both the strict mechanical properties called for in grain size requirements. The controlled carbon content of 304L allows it to retain excellent resistance to corrosion in most atmospheres with good oxidation and reduction.
