Review wear conditions 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. Record the actual operating range and how it was measured.
Plan a controlled trial
Define the current condition, proposed change and failure criterion before comparing measured results.
Review with a drawing
Use the application checklist with a drawing when the part has tight tolerances or a history of failure.
Tungsten Carbide Wear Life Estimator
Organize operating conditions for a tungsten carbide versus steel application review. This tool provides qualitative discussion points. It does not predict service life or a material improvement multiplier.
Tungsten Carbide Wear Life Estimator
This tool helps engineers and buyers collect the operating conditions needed to compare steel and tungsten carbide. It provides a qualitative checklist; it does not replace a wear test or predict which material will last longer.
Enter the wear mechanism, abrasiveness, load, speed, environment and any measured steel service life. The result preserves these inputs and identifies topics to review; it does not calculate a life multiplier.
Method: Qualitative application checklist, version September 15, 2026. Actual wear life depends on the complete part, material and operating conditions. Record measured results from a controlled trial before making a production decision.
If your application involves abrasion, slurry exposure, impact or high loads, include the failure history and relevant operating details in the material review.
Frequently Asked Questions
How accurate is the Wear Life Estimator?
Does tungsten carbide always outlast steel?
Do corrosive/wet environments affect wear life?
What should I do after using the estimator?
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 checklist collects the information needed to review a possible material change. It does not predict wear life or assign an improvement multiplier. 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.
Before 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.
Compare measured trial results
Compare the current material and a proposed alternative using the same geometry, operating conditions and failure criterion. Keep a record of load, speed, environment, finish and measured wear so the result can be evaluated before a production change.
When the part is already in service, include actual maintenance notes or measured wear if available. Real field behavior provides evidence for the material review.
Use the checklist to ask better production questions
Application details help frame the next question: review the grade, geometry, finish, load or material pair. This checklist supplies discussion points, not a prediction of service life.
When evaluating a material change, 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 checklist to improve the RFQ
Include known changes in load, speed, contact material, lubrication or grade with the drawing and measured wear history. It helps Extramet understand whether the issue is material choice, geometry, finish, or operating condition.
Method: qualitative application checklist, version September 15, 2026. Numerical improvement factors are not assigned. Production performance must be established for the full operating environment.
