API Corrosion and Materials Professional Sample Questions (Q98-Q103):

NEW QUESTION # 98
A hard, brittle surface layer will develop on some alloys due to exposure to high temperature process streams containing high levels of nitrogen compounds such as ammonia or cyanides, particularly under reducing conditions, is called _______.

  • A. Nitriding
  • B. Spheroidization
  • C. None of the above
  • D. Carburization

Answer: A


NEW QUESTION # 99
Which of the following is a critical factor for chloride stress corrosion cracking?

  • A. Presence of nickel content less than 8%
  • B. Presence of nickel content higher than 35%
  • C. Use in an alkaline pH region
  • D. Presence of oxygen

Answer: D

Explanation:
According to API RP 571, in the section on "Chloride Stress Corrosion Cracking (Cl-SCC)", several critical factors are outlined that contribute to the initiation and propagation of this mechanism. The document states:
"Critical factors include the presence of chlorides (even at ppm levels), oxygen, elevated temperatures, tensile stress, and susceptible materials such as austenitic stainless steels and some nickel alloys."
"Oxygen is an accelerant and promotes pitting that can lead to SCC initiation." (Reference: API RP 571, 3rd Edition, Section 4.2.2.2) Therefore, the presence of oxygen is a well-documented critical factor in Cl-SCC. It acts in conjunction with chlorides to initiate localized pitting, which then progresses into cracking. Hence, option B is the correct choice.


NEW QUESTION # 100
High strength steels are susceptible to LME when they come in contact with molten ________.

  • A. Both A and C
  • B. Zinc
  • C. Lead
  • D. Cadmium

Answer: A


NEW QUESTION # 101
Both sulfide stress corrosion cracking and stress-oriented hydrogen-induced cracking are most often found in:

  • A. Hardened steels.
  • B. Steel weldments.
  • C. Areas where there is significant hydrogen blistering.
  • D. Areas with temperatures above 300°F (149°C).

Answer: A

Explanation:
API RP 571 explains that both Sulfide Stress Cracking (SSC) and SOHIC are:
"Strongly influenced by material hardness. Carbon and low alloy steels with hardness exceeding 22 HRC (248 Brinell) are most susceptible."
"They occur in hardened steels under tensile stress, in the presence of wet H#S environments." (Reference: API RP 571, Sections 4.2.2.1 and 4.2.2.7 - SSC and SOHIC) Therefore, hardened steels are the common factor for both mechanisms, making option C the correct choice.


NEW QUESTION # 102
Carbon dioxide (CO(2)) corrosion results when CO(2) dissolves in water to form ________.

  • A. Carbonic acid
  • B. Hydrofluoric acid
  • C. Carbon monoxide
  • D. None of the above

Answer: A
