Client: A major crane manufacturer in Ukraine.
Product: Two pieces of rough-machined wheel samples.
Material & Process: 42CrMo4 alloy steel with Quenching & Tempering (QT).

Key Requirement: 100% Ultrasonic Testing (UT).

Process:

1. Production: Forging, rough machining, and QT heat treatment.

2. Inspection: 100% UT performed on both samples to ensure zero critical internal flaws.

3. Documentation: Full material certificates, heat treatment records, and UT reports were compiled.

4. Delivery: Approved samples and complete documentation package were shipped.

Outcome: The samples passed all inspections, meeting the client's stringent safety and quality standards. This successful sample validation paved the way for future bulk order discussions.
