20Cr Steel Grade. 20Cr steel is a kind of Chinese GB standard alloy steel. It has good comprehensive mechanical properties after quenching and low temperature tempering:good low temperature impact toughness and temper brittleness is not obvious. Quenched and Tempered Alloy Steels - Special steel china Quenching and tempering is a two-step process in which the metal is first heated to extreme temperatures and quickly cooled in water to harden the steel (known as quenching). The metal is clamped securely to avoid warping. The steel is then tempered, in order
