Your API Corrosion and Materials Professional Questions, Answered

Yes. Actual4Labs provides a free PDF demo of the API-571 practice questions, so you can check the format and quality before paying anything. Every purchase also includes 365 days of free updates, and once that period expires you can extend the update service at a 50% discount from your member zone.

The API-571 exam gives you 195 minutes to work through 110 (100 scored, 10 unscored pretest) questions, so the clock moves faster than most candidates expect. Keep a steady pace on every item, flag the ones that stall you, and circle back with the time you have banked instead of getting stuck. Time pressure is mostly a rehearsal problem: run at least one full timed mock in the Actual4Labs test engine before your appointment, and the real countdown will feel familiar rather than threatening.

The API-571 exam — officially titled Corrosion and Materials Professional — is the API test you pass to earn the Corrosion and Materials Professional certification. It sits at the Professional level of the API certification program. Related certifications include API 510 Pressure Vessel Inspector, API 570 Piping Inspector, API 653 Aboveground Storage Tank Inspector. If that is the credential you are after, the 151 practice questions at Actual4Labs map directly to its official objectives.

The API Corrosion and Materials Professional blueprint is organized into 6 domains. The first three are:

  • Other Damage Mechanisms (15%)
  • Mechanical and Metallurgical Failure Mechanisms (15%)
  • High-Temperature Corrosion and Degradation (15%)

The complete, current topic list appears in the exam outline section above — review it before you start drilling the Actual4Labs practice questions.

Hold current API 510, 570 or 653 certification; or meet education + experience requirements: BS/BS in engineering/tech + 1 year, 2-year degree + 2 years, high school + 3 years industry experience (past 10 years)

Eligibility rules do change, so confirm the current requirements on the official exam page before you apply: https://www.api.org/products-and-services/individual-certification-programs/certifications/api571.

If you take the corresponding API-571 exam within 60 days of purchase and do not pass, you can apply for a full refund under our money-back guarantee. Send a scanned copy of your exam enrollment slip together with the official Score Report PDF within 2 days of your exam date, and your claim will be processed within 7 days. Keep in mind that the candidate name must match the purchaser name, and the guarantee does not cover attempts made within 3 days of purchase, materials that were downloaded but never used in an actual exam sitting, free resources, or expired orders. If you would rather keep studying, you can swap the refund for two free exam products of equal value while keeping the update service on your original purchase. Delivery itself is instant: the files are emailed to you within one minute of payment (if nothing arrives within 2 hours, check your spam folder and contact our support team), and there is no limit on how many computers you install them on.

You can register for the API-571 exam through any of these official channels:

Depending on your location, you can take the API-571 exam Computer-based testing (CBT) at Prometric test centers; online proctored option available.

The passing score for the API-571 exam is 70% / Scaled score determined by API, and the official registration fee is $440 USD. Remember that an unsuccessful attempt means paying the full $440 USD again to retake it, so booking too early is the expensive way to find out you are not ready. Test yourself with the Actual4Labs practice questions first; once you can clear 70% / Scaled score determined by API comfortably on timed runs, scheduling the real exam becomes a much safer bet.

API points API-571 candidates to the following official training options:

Whichever course you pick, round it out with the 151 practice questions at Actual4Labs — courseware builds the theory, and timed practice turns it into exam-day speed.
