Color Code: Dura-Form is a heat treated tooling alloy which is oil-quenched and tempered to develop a full balance of mechanical properties. Dura-Form heat treated alloy has every requisite for excellent brake die service, high wear resistance, adequate toughness, high resistance to impact, and good machinability. Dura-Form is stress relieved before the final gag straightening process to ensure a minimum of residual stresses, and to eliminate warping and bowing.
