Surface Treatment

Scope of supply

Not only an aesthetic matter

IRIZAR FORGE keeps surface clean free of defects permanently during all production processes: During Forging, surface is permanently cleaned by water pressure on hot red piece to avoid surface scales flowing into inside during forming process.

Before heat treatment, forging surface is cleaned by grinding one by one in order to eliminate any surface defect, indication, incrustation, marks or scales, that could affect its mechanical & physical status and results. Before DT & NDT, forging surface is cleaned by shot-blasting one by one to eliminate scale after heat treatment.

The hook is a critical item for several reasons, but above all because during its lifetime is subjected to FATIGUE, and this effect can cause originate small discontinuites in an area, turning it into a crack in a premature way and therefore, not only radically shortening the hook’s life, but risking sudden failure.
