Abstract
PURPOSE: To keep hardness in a quench hardened state and in a tempered state before precipitation hardening at Hr about C42, namely easily cuttable hardness and to improve toughness of the central part of steel, by lowering C than that of conventional steel (3% Cr - 3% Mo steel) and increasing Cr.
CONSTITUTION: C, 0.10 to 0.22%; Si, 0.15 to 1.5%; Mn, less than 1.0%; Cr, 4.00 to 6.00%; Mo, 2.60 to 4.00%; V, 0.20 to 1.00%; Fe, the rest; all the percentage being by weight basis.
USE: Large size metal mold with mold weight larger than 50kg, especially for use in hot forging.
