Free sample questions from API 577

  1. Following the completion of PWHT, which check serves as an indicator that the heat treatment was acceptable?

    • A. Visual inspection for color
    • B. Field hardness check ✓
    • C. Ultrasonic thickness check
    • D. Dimensional survey
    • E. Dye penetrant testing

    An acceptable hardness value after PWHT indicates that the heat treatment successfully reduced the hardness to within specified limits. API 577, 9.4.3.1

  2. Which alloying element is recognized as having the greatest effect on the mechanical properties and hydrogen cracking susceptibility of the HAZ?

    • A. Chromium
    • B. Nickel
    • C. Carbon ✓
    • D. Molybdenum
    • E. Manganese

    Carbon is the primary driver of tensile strength and hardness; high levels increase the risk of hydrogen-induced delayed cracking. API 577, 10.8.2
