Finishing Processes

Straightening

Steel often has to be mechanically straightened after Q&T due to the distortion that takes place during the hardening process.  Rounds, structural shapes, and flat bar products are straightened using hydraulic presses or machine straightening.  If required by the specification or customer, stress relieving may be performed.

Shot Blasting

Shot blasting utilitizes small beads of steel accelerated by a wheel turning at over 3000 RPM to remove oxidation and scale from the steel surface.  Blasting with steel shot  has advantages over sandblasting and other abrasive media because only a minimal amount of dust is created.

Powder Coating

Powder coating applies a statically adhering powder to parts.  The powder coating is then cured in a oven to produce a very durable surface.  The primary advantage of powder coating is that they are applied dry without noxious solvents and are much more environmentally friendly.
