The effects of quenching temperature, vacuum degree of cooling system, quenching oil temperature and annealing temperature on microstructure and mechanical properties of Cr12 steel were studied.

A discussion was made of the procedure for forging Cr12 steel, a high alloy ledeburiticdie steel with low plasticity and high resistance to deformation, mainly concerning the process features,the selection of steel ingot and forging ratio, the formulation of forging procedures, and the qulity-relatedproblems associated with the forging practice.
