Cr-Mo vs Cr-V Impact Sockets. - Thorium ToolsJan 19, 2020 · Cr-Mo is a heat-hardened steel alloy, with the inclusion of molybdenum that gives the alloy a property of toughness and flexibility. Cr-Mo will absorb percussive impact better than Cr-V without being brittle. Over time Cr-Mo sockets may stretch and lose their shape, but they are less likely to shatter and cause injury.

Weld Repair for Pressure Vessels Made From Cr-Mo Steels Jan 10, 2011 · Pressure vessels made from Cr-Mo steels are utilized for high temperature and high pressure services including hot hydrogen services. After long term operation, there are several past experiences of damages and/or degradation of materials such as temper embrittlement, creep embrittlement, hydrogen attack and hydrogen embrittlement.

    Weldability of Cr-Mo Steels Welding Construction

    WHAT ARE CR-MO STEELS?? Steels containing 0.5-9% Cr and 0.5-1% Mo are referred to as Cr-mo steels. The carbon content in such steels varies in between 0.10 to 0.20%. Because these steels contain very low carbon hence they are weldable. What is temper embrittlement, and how can it be - TWIIn order to assess susceptibility to temper embrittlement in Cr-Mo steels, two compositional parameters are commonly employed, the Watanabe J factor (1) and the Bruscato X factor (2). J= (Mn + Si) (P + Sn) x10 4 (in wt %), has been applied to parent steels and weld metals. X= (10P + 5Sb + 4Sn + As)/100 (in ppm), is applied to weld metals.
