DYNA-LOY 41L43 is a cold-drawn alloy steel developed for those applications that require excellent machinability along with a hardness range of Rockwell C 33 to 55. Its chemical composition permits maximum machinability and good surface finish for the tensile strength range 150,000 to 280,000 psi. It is recommended for a wide range of uses such as gears, bushings and fasteners. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-341.
