Heat Treatment of High Alloy Graphite Irons | Cast Irons | Metallurgy
The graphite could be in flake (grey) form, or as nodules (ductile iron). These cast irons are divided in following classes: I. Nickel-alloyed, austenitic graphitic irons (Ni-Resist)- Both grey and nodular forms are used for high corrosion resistance, and for high-temperature service. II. High silicon (14.5% Si) grey irons are used in applications requiring corrosion-resistance. III. High silicon (4-6%) grey [...]
