JIUWAN Laboratory
Steel Wear Resistance Control
We perform spectral analysis on every batch of Komatsu and Caterpillar parts to eliminate all hidden defects before shipment.


Spectrum Analysis
Alloy Structure Inspection
Every batch is tested in a certified laboratory to verify the chemical composition of the steel.
Strict quality control eliminates defects and extends the service life of parts during heavy-duty equipment operation.
Control Stages
Three Inspection Stages
Incoming Spectral Analysis
Ultrasonic Defectoscopy
Brinell Hardness Test
Verification of metal chemical composition in full compliance with Komatsu and Caterpillar OEM standards at the raw material incoming stage.
Scans the internal structure of castings to detect hidden cracks and voids in the steel.
Final surface hardness test to verify the wear resistance of finished parts.
Steel Quality Documents
Request laboratory test reports and steel quality compliance certificates for your heavy machinery.
