15V41R allows us to meet Grade 5 chemical and mechanical properties without having to heat-treat the material. This is due to the steel being a modified version of AISI 1541. The modifications are made in the percentage of alloying elements, which help shape the properties of the material. 15V41R can be used in bolts, threaded rod, and other fasteners. One of the most common applications is U-Bolts. 15V41R is the only medium-carbon steel offered by AATP.
