MaxxShot
Maxxshot is a specialized surface treatment process to induce compressive residual stress on the surface & sub surface, thereby increasing the Heat Check Resistance, avoiding Pitting Corrosion & Stress Corrosion Cracking (SCC).
MaxxShot Plus
MaxxShot Plus is a Duplex process in which, MaxxShot is carried out incombination with a superior controlled Nitriding process (Tufftride) followed bysecondary surface preparation and Magnetite. MaxxShot Plus with higher Nitriding case depth increases the life of press forgingdies significantly.
Heat Checking is a tensile stress fatigue which is influenced by following factors:

Casting process parameter
MaxxShot is a highly controlled bombardment process which creates a reactive action from the material core thus resulting in a beneficial surface & sub surface compressive residual stress. MaxxShot process includes Stress tempering, Removing EDM layer & Correcting Surface deterioration, Inducing Compressive Stress & Magnetite Coating.
