API API-571 Dumps - Pass Corrosion and Materials Exam in 2026
The API-571 Corrosion and Materials exam is part of the API Certifications track and focuses on corrosion science, materials behavior, and inspection-related decision making. It is designed for professionals who need to understand how materials perform in service and how damage can affect asset integrity. Passing this exam demonstrates practical knowledge that supports safer operations, better maintenance planning, and stronger inspection outcomes.
Exam Topics and Approximate Weightage
| # | Exam Topics | Sub-Topics | Approximate Weightage (%) |
|---|---|---|---|
| 1 | Fundamentals of Corrosion | Corrosion types, electrochemical principles, environment effects | 20% |
| 2 | Materials Selection and Evaluation | Material properties, compatibility, selection criteria, testing methods | 20% |
| 3 | Damage Mechanisms and Inspection | Degradation modes, inspection planning, failure indicators, monitoring basics | 25% |
| 4 | Corrosion Control and Mitigation | Coatings, cathodic protection, chemical treatment, design considerations | 20% |
| 5 | Industry Standards and Codes | Code awareness, inspection requirements, compliance concepts | 15% |
This exam tests more than memorization. Candidates must understand corrosion behavior, apply material selection knowledge, recognize damage mechanisms, and interpret mitigation and inspection concepts in practical scenarios. A strong grasp of industry standards and codes is also important for answering questions accurately and confidently.

Polythionic acid stress corrosion cracking is:
API RP 571 under Polythionic Acid Stress Corrosion Cracking (PTA SCC) specifies:
''Cracking is usually intergranular, and often localized, especially in sensitized austenitic stainless steels exposed to sulfur-containing environments during shutdown or cleaning.''
''It is not always visible on inspection and may only become evident when a leak occurs.''
(Reference: API RP 571, Section 4.2.2.5 -- PTA SCC)
Hence, option C is correct as it best describes the detection difficulty and behavior of PTA SCC.
Hydrogen permeation or diffusion rates associated with wet HS damage of carbon steel and low-alloy steels have been found to be minimal at a pH of:
API RP 571 discusses this under Wet HS Damage -- Hydrogen Blistering, HIC, SOHIC:
''Hydrogen generation is reduced as pH increases. At pH 9 and above, the corrosion potential is less favorable for hydrogen charging and thus permeation into the steel is minimal.''
''Most wet HS cracking damage mechanisms are accelerated under acidic conditions (pH < 7).''
Hence, high pH (around 9) environments offer the most protection against hydrogen damage, making option D the correct choice.
Which of the following is the most significant result of spheroidization in steels?
As per API RP 571 Section 5.3.2.3 (Spheroidization):
''Spheroidization is the transformation of the microstructure of steels into spherical carbides, leading to reduced strength and hardness, especially after extended high-temperature exposure. It's commonly seen in carbon and low alloy steels in refining heaters and reactors.''
It reduces strength and sometimes hardness.
It increases ductility, not reduces.
SCC potential is not directly tied to this change.
Therefore, Option D (Loss of strength) is correct.
Damage from oxidation is usually determined by:
API RP 571 on Oxidation indicates:
''Oxidation is a surface loss phenomenon that generally results in uniform thinning. Ultrasonic thickness measurements are typically used to monitor metal loss in oxidizing environments.''
''Metallography may be used to confirm oxide scale structure but is not necessary for routine evaluation.''
Hence, option B is the most appropriate standard method.
(Repeated) The best method for finding damage from sigma phase embrittlement is:
Same as above. Sigma phase formation is a microstructural phenomenon and not typically detected by NDE methods like magnetic particle or surface hardness testing.
Therefore, metallographic testing remains the definitive detection method, confirming option D again as the correct answer.
