After forging & polishing, pieces are submitted, one by one or in a batch, to temperature and medium changes (air, water, oil, polymer…), without changing the state (always solid), applying heating and cooling at controlled temperatures, with the aim of improving its physical and mechanical properties, especially:

• * Toughness
• * Strength
• * Elasticity

The most usual treatments applied to the most commonly recognized materials for hook and production accessories (mentioned above) are:

• * Quenched and tempered (QT)
• * Normalized (N)
• * Annealed (A)

Consequently IRIZAR FORGE is developing R&D projects related to material grades, properties & heat treatments, applying deep metallurgical expertise that is allowing leadership in our goal markets and industries.
