Estimate wear life before changing material or geometry.
Wear life depends on more than hardness. Load, speed, contact material, finish, lubrication, impact, and part geometry all affect how long a carbide component will last in service.
Use known conditions
Enter the best available operating details rather than ideal numbers. A realistic input is more useful than a perfect-looking estimate.
Compare scenarios
Test a current condition against a changed grade, speed, or load to see which variables matter most.
Review with a drawing
Use the estimate as a conversation starter when the part also has tight tolerances or a history of failure.
Tungsten Carbide Wear Life Estimator
Estimate relative wear life for tungsten carbide versus steel for your application. This is a directional tool that helps you compare materials and start the right grade conversation with Extramet Products.
Need help interpreting the result?
Use the grade selector for a first-pass material direction, then send the current failure mode and drawing if the application is ready for quote review.
What the estimator can and cannot tell you
The estimator is useful for comparing scenarios, especially when you are deciding whether a material change is worth reviewing. It does not replace a drawing review, because sharp corners, unsupported geometry, surface finish, misalignment, and impact can shorten service life even when the material looks correct on paper.
If the estimate is being used for a production decision, include the current service life, the target service life, the contact material, and any photos or notes that show how the part is wearing. Those details help separate normal abrasive wear from chipping, cracking, corrosion, or heat-related damage.
Use wear estimates as a comparison, not a promise
The most useful output is often the difference between two scenarios. Compare a current grade against a possible alternative, or compare a current load against a reduced load. If the estimate changes sharply, that tells the team which variables deserve closer review before a material or geometry change is quoted.
When the part is already in service, include actual maintenance notes or measured wear if available. Real field behavior helps confirm whether the calculator is pointing in the right direction.
Use the estimate to ask better production questions
A wear estimate is most useful when it leads to a practical next question: change the grade, change the geometry, improve the finish, reduce load, or rethink the material pair. It should not be treated as a promise of service life.
If the estimate suggests steel is the wrong fit, compare the tradeoffs in the carbide versus steel guide. If the next step is a quote, send the print, current material, wear pattern, load, speed, contact material, and target life.
Use the wear estimate to improve the RFQ
The estimator is most useful when it helps you ask better production questions. If a change in load, speed, contact material, lubrication, or grade has a large effect on the estimate, include that context with the drawing. It helps Extramet understand whether the issue is material choice, geometry, finish, or operating condition.
Wear-life estimates should be treated as comparison data, not a guaranteed service-life promise. Real production performance depends on the full environment.
