TRIMRITE®

TRIMRITE® is a hardenable martensitic stainless steel that provides a moderately high level of corrosion resistance, hardness up to Rockwell C 51, good cold formability, and ease of heat treatment, all of which combine to provide an alloy that has been used for many applications. TRIMRITE® is balanced to be fully martensitic in the hardened condition and is magnetic in all conditions. The alloy can be hot worked, cold worked, machined, and heat treated using the same equipment and methods used for 410 stainless steel.

TRIMRITE® is used in fasteners, especially self-drilling types, medical and surgical applications for cutting and scraping tools, and demanding industrial and energy applications. In laboratory tests, self-drilling fasteners of TRIMRITE® heat treated to Rockwell C 50 have shown good drilling capability. At a constant drill load of 35 pounds and a speed of 2500 rpm, No. 8 x 3/4 in. self-drilling fasteners drilled through 0.062 in.-thick cold-rolled 1010 carbon steel at Rockwell B 80 in 3.0 seconds or less.
