API Corrosion and Materials Professional 認定 API-571 試験問題 (Q126-Q131):

質問 # 126
There is currently no known metal alloy that is immune to _________ under all conditions.

A. None of the above
B. Metal dusting
C. Decarburization
D. Carburization

正解：B

質問 # 127
Temper embrittlement is a metallurgical change that is:

A. Readily apparent and can be confirmed through metallography
B. Not readily apparent but can be confirmed through impact testing
C. Not readily apparent but can be confirmed through tension testing
D. Readily apparent and can be confirmed through impact testing

正解：B

解説：
API RP 571 describes temper embrittlement as a subtle metallurgical change that reduces impact toughness without obvious macrostructural change:
"Temper embrittlement is not readily apparent by visual or standard tensile testing. It is confirmed by Charpy impact testing which measures toughness at low temperatures."
"It typically affects Cr-Mo steels exposed to intermediate temperatures (650°F to 1100°F) for extended times." (Reference: API RP 571, Section 4.2.1.4 - Temper Embrittlement) Thus, the condition is not visually or physically apparent, but is confirmed through impact testing, making option D correct.

質問 # 128
The "L" grade of stainless steels will sensitize if exposed more than several hours above _______ or long term above _____.

A. 1100(o) F, 800(o) F
B. 1000(o) F, 750(o) F
C. 1200(o) F, 800(o) F
D. 1000(o), 600(o) F

正解：B

質問 # 129
Sour water corrosion in _________ containing environments may be accompanied by carbonate SCC.

A. CO(2)
B. O(2)
C. H(2)S
D. H(2)O

正解：A

質問 # 130
Hydrogen stress cracking is normally found in:

A. high strength low alloy steels and carbon steels.
B. mild carbon steels at high temperatures and high hydrogen partial pressure.
C. stainless steel internals such as trays.
D. the presence of sulfuric acid.

正解：A

解説：
Hydrogen Stress Cracking (HSC) is a subclass of environmental cracking that occurs in certain materials when hydrogen is present. According to API RP 571, HSC typically affects high-strength low alloy steels and carbon steels, particularly under tensile stress in a hydrogen-containing environment. This includes areas like weld-affected zones and hard spots in steels.
* From API RP 571 Section 5.1.2.1 (Hydrogen-Induced Cracking):
"Hydrogen stress cracking (HSC) can occur in carbon steel and low alloy steels in environments containing hydrogen at ambient to moderately elevated temperatures (up to 200°F or 93°C)... Hardness is a critical factor for HSC. High hardness in welds and heat affected zones (HAZ) are most susceptible."
* Additionally, API RP 939-C does not directly define HSC but reinforces the relationship between hydrogen exposure and metal integrity, particularly under conditions not exceeding 450 °F (230 °C) for hydrogen services.
Thus, option A is correct, as it directly reflects the metal types most susceptible to HSC in operational environments defined by API RP 571.
