Have you encountered any of these defects or failures?

• Cracks
• Chipping or Spalling
• Distortion
• Failure of Quenched Steel
• Soft Spots in Hardened Areas
• Failure to Harden to a Sufficient or Uniform Depth to Attain Maximum Hardness?

Distressing indeed are the occasions when a carefully machined part breaks, either in the quenching operation, or some time later, when the part is in service. Some manufacturers regard such problems as a mystery or an unavoidable evil. They are not! A thorough investigation will reveal that a failure does not just happen, but is due to an avoidable cause, which may or may not be the responsibility of the heat treater.

General Metal's ability to minimize these failures and develop the desired mechanical properties of steel is the result of our extensive knowledge and experience in controlling microstructure. Each job analysis, including the chemistry of the material, is considered as having individual transformation characteristics, and the heat treating cycle is "tailor made to fit". To develop a desired microstructure, General Metal has, at their disposal, a variety of procedures.

The choice depends on many factors — for example: the types of furnaces and atmospheres, the weight and shape of the part, the temperature used, and the time available for the process to insure the end quality required.

The experience, the diversity, and the availability of equipment to do a specific job in conformance with precise customer specifications, producing a quality product reliably and on time is what makes General Metal Heat Treating so important. Important in solving heat treating problems for those not possessing heat treating facilities, and in performing for captive heat treating departments where the particular heat treatment cannot be adequately processed because of limitations in plant space, personnel, equipment, production scheduling, particular expertise and/or fuel.
