Stress relieving and heat treatment

Stress Relief

Once fabricated and welded, and prior to the machining process Key Plant stress relieves sub-sections and welded components.

For Key Plant this is particularly important on rotator and roller bed frames, manipulators and seam welder beds.

Applying heat into the welded structures to prevent distortion and stress corrosion cracking, helps minimise dimensional changes when we machine and continue the Key Plant manufacturing process.
