Abstract
PURPOSE: To make Cr plating useless and to improve the normal and high temperature strength. Glauber's salt corrosion resisting property and mold separating property, by fixing Cr equivalent computed by a specific formula at the above mentioned lowWmedium Cr-high C-high Si-Ni base steel.
CONSTITUTION: The above mentioned steel is composed of C; 0.1W0.6% (suitably 0.2W0.4%), Si;1W4%(1.5W3.5%), Mn ≤1.5%, Ni;1.55W6% 2W4%), Cr;12.5W 23% (14W20%), Fe;balance and innevitable impurities and also, Cr equivalent, shown in the following formula, is made less then 15. That is, Cr equivalent = Cr- 40C-2Mn-4Ni + 6Si + 4Mo + 8V + 2W-40N. Preharden hardness of the steel for this glass forming metal mold, is HRC 10W35 and oxidation resisting property at less than 700°C is superior especially.
