SAE AMS 2750 H was released in July of 2024. This update supersedes AMS 2750 G and affects companies that work in metal processing, especially for the aerospace industry. Thermo-Temp Inc. has the skilled technicians and equipment to help you comply with these new requirements and we have already updated our own processes. Please don’t hesitate to contact us if you would like consulting and training to meet these new standards or if you require temperature uniformity surveys and calibration services for your thermal processing equipment and tools.
See the updates listed below.
