APPLICATIONS:
Ni-Hard: This is a white cast iron for use is high abrasion and low corrosion services. This material may be hardened up 750 Brinnell. This is not a machinable material and castings can only be finished by grinding. Use in a 4 - 8.5 pH.
HCI: This is a white cast iron for use in a high abrasion application in a moderately corrosive environment. This material may be hardened up to 750 Brinnell. This material can be annealed for machining and re-hardened up to desired Brinnell hardness. Use in a 3 - 9.5 pH.
CD4MCu: This is an Austenitic steel and is used in applications where a moderate amount of abrasion will occur plus the pumped media is corrosive. This material is machinable and will reach a Brinnell hardness up to 450. When applied in high abrasion situations this material will surface work harden. Use in a 2 - 13.5 pH.
