Question 10

For 5Cr-0.5Mo, what is the threshold temperature for creep?

    Correct Answer: B

    The threshold temperature for creep for the 5Cr-0.5Mo alloy is 800º F. This is the temperature at which the material begins to experience significant creep, which is a time-dependent deformation under stress at high temperature.
