API Corrosion and Materials Professional Sample Questions (Q149-Q154):

NEW QUESTION # 149
At elevated temperatures, dissimilar weld metal cracking is aggravated by the diffusion of carbon out of the weld metal and into the base metal. The temperature at which carbon diffusion becomes a concern is above ________.

A. 750(o) F
B. 900(o) F
C. 700(o) F
D. 800(o) F

Answer: D

NEW QUESTION # 150
How can temper embrittlement be prevented if a material contains critical levels of the appropriate impurity elements and is exposed in the embrittling temperature range?

A. Use of a controlled pressurization sequence
B. Specification of Charpy V-notch impact test
C. Postweld heat treatment (PWHT) of repairs
D. Embrittlement cannot be prevented

Answer: B

Explanation:
API RP 571 provides the following guidance regarding temper embrittlement:
"For materials that contain impurity levels which make them susceptible to temper embrittlement, the most effective preventive measure is to specify low FATT or Charpy impact energy requirements."
"These requirements ensure the material retains adequate toughness even if embrittlement occurs."
"While temper embrittlement itself cannot always be fully prevented during long-term exposure to temperatures between 650°F and 1070°F (343°C-577°C), its effects can be identified and mitigated through impact testing criteria." Therefore, option C is correct. Specification of Charpy V-notch testing ensures material selection accounts for embrittlement susceptibility and maintains service integrity.

NEW QUESTION # 151
Nitriding begins above ________ and becomes severe above _______.

A. 800(o) F, 1000(o) F
B. 500(o) F, 800(o) F
C. 600(o) F, 900(o) F
D. 700(o) F, 1100(o) F

Answer: C

NEW QUESTION # 152
The removal of surface material by impacting materials is called:

A. IPC (imparting particle corrosion)
B. Erosion
C. Erosion or erosion corrosion
D. Erosion corrosion

Answer: B

NEW QUESTION # 153
(A metal cracks because of stress relaxation during postweld heat treatment (PWHT) of a heavy wall section.
This type of cracking is best categorized as:)

A. Thermal fatigue cracking
B. Temper embrittlement cracking
C. Reheat cracking
D. PWHT cracking

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Reheat cracking is explicitly defined in API RP 571 as cracking that occurs during postweld heat treatment or elevated temperature exposure due to stress relaxation in the heat affected zone of welded components.
Key characteristics per API RP 571 include:
* Occurs during PWHT or high-temperature service
* Associated with creep-strength-enhanced steels (e.g., Cr-Mo steels)
* Driven by stress relaxation and grain boundary weakness
* Most common in heavy wall sections
Why the other options are incorrect:
* Option A (PWHT cracking) is a non-specific term; API classifies this mechanism as reheat cracking.
* Option B (Thermal fatigue) requires cyclic temperature changes, not stress relaxation.
* Option D (Temper embrittlement) does not cause cracking during PWHT.
API RP 571 uses reheat cracking as the correct classification.

* API RP 571 - Section on Reheat Cracking
