: : R>Steel is a low-alloy cold work die steel of domestic tool steel. This steel has certain hardenability and wear resistance, small quenching deformation, uniform carbide distribution and fine particles. This steel has good plasticity and toughness, and its wear resistance is relatively low compared to
>r
: : R> steel. The mold cavity tends to shrink after oil-cooling quenching, the flat surface is easy to bulge, and the warpage tendency is prominent. After graded quenching, the inner hole of the mold cavity tends to expand, but the warpage tendency is significantly reduced. Oil-cooled hardening diameter
