CarTech TrimRite stainless 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 which has been used for many applications such as fasteners, especially self-drilling types, cutlery, food processing equipment, valve parts, gauges, guides, shafting, conveyor chain and instruments.

CarTech TrimRite stainless has also been used in medical and surgical applications for cutting and scraping tools.

The alloy can be hot worked, cold worked, machined and heat treated using the same equipment and methods used for Type 410 stainless steel.

CarTech TrimRite stainless is balanced to be fully martensitic in the hardened condition and is magnetic in all conditions.

In laboratory tests, self-drilling fasteners of CarTech TrimRite stainless 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" self-drilling fasteners drilled through 0.062"-thick cold-rolled 1010 carbon steel at Rockwell B 80 in 3.0 seconds or less.
