The Test House (TTH) is pleased to announce that it is now able to offer a sub-contract heat treatment service at its site in Cambridge. The facility has been set up and will be run in accordance with our ISO 9001 certification and also in line with the requirements laid out in AMS 2750 Rev E.
The new heat treatment service facility includes a large vacuum furnace with a working thermal uniformity surveyed area (TUS) of 750mm H x 750mm W x 1000mm and a working surveyed temperature range of 250°C to 1200°C. The furnace typically runs with vacuum levels of <1 x 10-5 mbar, but can also be used in a partial pressure mode using inert gases such as nitrogen, argon or 5% hydrogen in nitrogen. An air furnace is also available with a TUS working area of 500mm H x 500mm W x 550mm D and a working surveyed temperature range of 150°C to 700°C. The air furnace also has a controlled cooling option available.
Typical heat treatment processes that can be performed include:
- Solution and ageing
- Hardening and tempering
- Stress relieving
- Post weld heat treatment
TTH is able to carry out post heat treatment testing services through its UKAS approved laboratories. Testing services include:
- Tensile testing
- Charpy testing
- Hardness testing
- Metallographic characterisation
- NDT inspection pre and post weld heat treatments
