API Corrosion and Materials Professional Sample Questions (Q72-Q77):

NEW QUESTION # 72
The 300 series stainless steels (austenitic stainless steels) are generally resistant to oxidation up to what temperature?

  • A. 1400°F (760°C)
  • B. 1500°F (815°C)
  • C. 1600°F (871°C)
  • D. 1300°F (704°C)

Answer: B

Explanation:
According to API RP 571, under Oxidation:
"Austenitic stainless steels (300 Series) are generally used for oxidation resistance up to about 1500°F (815° C). At higher temperatures, scaling and loss of protective chromium oxide layers increase."
"Above these temperatures, specialized high-temperature alloys may be required." (Reference: API RP 571, Section 5.1.1 - Oxidation) Therefore, option C is the correct answer.


NEW QUESTION # 73
A form of mechanical fatigue in which cracks are produced as a result of dynamic loadings is _______.

  • A. Fatigue cracking
  • B. Spheroidization
  • C. Vibration-induced cracking
  • D. Stress cracking

Answer: C


NEW QUESTION # 74
Major factors affecting sulfidation are alloy composition, temperature and ________.

  • A. Concentration of sulfur
  • B. Time
  • C. Stress
  • D. Concentration of hydrogen

Answer: A


NEW QUESTION # 75
Hydrogen blisters may form as surface bulges on the ID, the OD on within the wall thickness of a pipe or pressure vessel. Blistering occurs from hydrogen generated by ______, not hydrogen gas from the process stream.

  • A. Sulfur
  • B. H2S
  • C. Corrosion
  • D. Hydriding

Answer: C

Explanation:
Explanation


NEW QUESTION # 76
The rate of spheroidization is affected by:

  • A. temperature and pressure.
  • B. temperature and microstructure.
  • C. type of steel and H# partial pressure.
  • D. exposure time and stress.

Answer: B

Explanation:
According to API RP 571 Section 5.3.2.3 (Spheroidization):
"Spheroidization is the transformation of the microstructure of carbon and low alloy steels when exposed to elevated temperatures for long durations. The rate of spheroidization depends on temperature, prior microstructure, and exposure time... The microstructure becomes less effective at carrying loads, and strength is reduced." Key influencing factors for the rate of spheroidization are:
* Temperature (higher accelerates the process),
* Microstructure (initial phase distribution and morphology).
Pressure and hydrogen partial pressure are not relevant for this transformation, nor is stress a primary driver.
Therefore, Option D (temperature and microstructure) is correct.
