Machinability: Good machinability (~75% of C36000 baseline). Mixed ferritic-pearlitic structure delivers smooth finishes and moderate tool life.
Weldability: Difficult to weld. Preheat to 250°C and use nickel-iron (ENiFe-CI) electrodes with controlled interpass temperatures.
Formability / Cold Working: Limited localized deformation only.
Heat Treatment & Annealing: Typically used as-cast. Normalizing from 900°C increases pearlite and strength.
Machinability: Good machinability (~70% relative to C36000 baseline). Higher pearlite content increases abrasive tool wear compared to 65-45-12.
Weldability: Difficult to weld. High pearlite and carbon content cause high cracking sensitivity. Thorough preheating (250°C–350°C) and post-weld stress relief or annealing are required.
Formability / Cold Working: Very limited cold forming; hot coining under controlled temperature possible.
Heat Treatment & Annealing: Commonly used as-cast. Normalizing from 900°C produces uniform fine pearlite and raises tensile strength toward 100 ksi.
