904L, UNS N08904

904L is the most common of the “4% Molybdenum” alloys. It was designed to be an upgrade to 316L and Alloy 20 without incurring the expense of Alloy C276. Alloy 904 has been surpassed in popularity by the “6% Molybdenum” alloys such as AL6XN®. Its availability in round bar is limited to metric sizes in 5mm increments. Consequently, inch-size diameter headed bolts are relatively expensive to manufacture.
