8740 CHROME MOLY: Until the development of today's modern alloys, chrome moly was popularly considered a high-strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice.

Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.
