Quality Control at MTC

Metals Technology Corporation has been ISO 9001-2000 registered by United Registrar of Systems.

Zero Defect Policy

Our MTC-2000 hardness testing sampling plan is based on the Metals Treating Institute MTI-2000 and ANSI/ASQC Z1.4-1993 standards with a Zero Defect Allowed policy.

Calibration System

Hardness Testers are calibrated by A2LA approved sources on a quarterly basis with shift verification performed daily using NIST traceable test blocks. Furnace instrumentation calibration is performed quarterly for MTC certified furnaces and annually for others.

Hardness Testing

We perform Normal, Superficial and Knoop Microhardness testing and also Brinell and Equotip testing. Additional mechanical properties can be analyzed by an outside A2LA certified Laboratory within a few days.

Metallurgical Staff

Degreed Metallurgical Engineers are on call for process evaluations and recommendations. Careful review of customer specifications is performed to provide step by step process instructions to our production personnel.

Metallurgical Laboratory

Our fully equipped metallurgy laboratory and trained technicians enables us to perform complete inspection of microstructures, accurate analysis of case depths ( total and effective) and surface hardness to assure conformance to customer requirements and specifications. We also have the capability of determining carbon content of steels.

Documentation / Record Keeping / Traceability

All work instructions are generated using state-of-the-art proprietary software. The computer-stored process instructions & inspection results allow for quick review of completed orders and test data. These instructions and results provide repeatability of process, traceability and if necessary, implementation of corrective action. Documentation consists of hard copies of processed orders, furnace charts and metallurgical mounts. They are maintained for seven years on premises.
