CQI-9 Heat Treatment Audit Services
VyVy provides CQI-9 Audit Services for automotive manufacturers, suppliers and heat-treatment companies that need an independent assessment of their heat-treatment system.
Our senior auditors assess the site against the applicable AIAG CQI-9 Heat Treat System Assessment, customer-specific requirements and the heat-treatment processes actually performed. The audit covers the system, process controls, pyrometry, equipment, applicable process tables and job audit requirements.

OUR SERVICE
CQI-9 Audit Services for Heat Treatment Processes
VyVy can audit your own facility or an external heat-treatment supplier. We can work against your own assessment format or directly against the applicable CQI-9 requirements.

CQI-9 gap assessments
Corrective-action verification
AUDIT SCOPE
What We Review During a CQI-9 Heat Treatment Audit
The scope is adapted to the processes and equipment used at the facility.
AREA
VERIFICATION
Heat Treat System
Responsibilities, controls, competence and quality planning
Pyrometry
Calibration, thermocouples, TUS, SAT and temperature monitoring
Equipment
Furnaces, alarms, controls, maintenance and process monitoring
Process Tables
Requirements applicable to the heat-treatment process
Job Audit
Actual production parameters, records and conformity
Our auditors compare the completed CQI-9 assessment with the condition of the process on site. A compliant assessment form is not enough if the furnace controls, records or production practices do not support it.
HEAT TREATMENT EXPERTISE
CQI-9 Audits Across Automotive Heat Treatment Processes
VyVy supports assessments across processes such as carburizing, carbonitriding, hardening, tempering, annealing, nitriding, ferritic nitrocarburizing and induction hardening.
Auditor profiles are selected according to the thermal process involved. This matters. An induction hardening line does not require the same technical understanding as a carburizing furnace or a continuous heat-treatment line.
