When many people think of heat-treating technical specifications or standards, they aren’t real sure where and how they are reviewed or designed … or even who designed them. Many believe it’s a few people in a small room that are far removed from the daily business of heat treating.

The truth is when it comes to the process of technical specification review and design, it is the hard work of many heat treaters just like you, the reader, who author and write several of the technical specifications. These individuals come from commercial heat treaters, captive OEMs and suppliers.

The Metal Treating Institute (MTI) and its Technical Standards Committee have a team of over 20 volunteers who meet quarterly via conference calls to work through the vast array of technical specifications and audit checklists being reviewed and rewritten by the following groups:

  • Aerospace Materials Engineering Committee (AMEC)
  • Nadcap
  • Automotive Industry Action Group (AIAG) – CQI-9
  • ASTM
  • SAE Additive Manufacturing Committee
  • ISO

The Technical Standards Committee identifies areas of concern and provides feedback and solutions to the various groups to ensure specifications have a good balance of ensuring strong quality and reasonableness in compliance.

The groups listed above host over 15 meetings a year combined on technical specifications. MTI also has over 75 member volunteers in attendance to help provide input and solutions to many of the specifications with direct impact on the commercial heat-treat supplier base.  

2017 and 2018 will be big years for technical specifications, with the long-awaited new 2759 and slash specs rollout in aerospace, CQI-9 revisions for automotive and the continuation of the new ISO 9000 rule changes taking place for all industries.

MTI’s Technical Standards Committee has recently been weighing in on some highly debated areas of the specifications, including:

  • Proper procedures for ITAR notification
  • Pyrometry
  • Auditor’s access to audit documents post-audit
  • Definition of effective case depth and who is liable for measurement
  • Who is responsible and liable for identification of counterfeit parts
  • New specifications being developed for additive manufacturing
  • Auditor consistency in compliance

These are just a small sampling of the many elements of technical specifications MTI’s Technical Standards Committee and numerous volunteers are actively involved with on behalf of more than 260 MTI member plants around the world.

Established in 1933, the Metal Treating Institute is a non-profit trade association representing the world’s largest network of commercial heat treaters, with plants in 40 states and five countries. Visit www.heattreat.net if you would like more information on MTI.
