Vacuum Metal Stress Relieving

Minimized Distortion, Bright Results

Welding, machining, milling, and cold working all induce stresses within materials. These stresses will cause unstable dimensional control downstream if not relieved thermally. Vacuum metal stress relieving is normally performed after rough machining, prior to final machining. Solar’s vacuum metal stress relieving produces bright, clean surface finishes, therefore often the part is stress relieved in a near net shape.
