Title
Hardness and Microstructural Changes in STS 420J2 during Annealing
김기돈 Ki Don Kim
Abstract
In order to determine the optimum condition for batch annealing of STS 420J2 martensitic stainless steel, several annealing treatments were done above and below the Ac₁ transformation temperature. At higher annealing temperature, the amount of dissolved carbides increased and more homogeneous and finer carbides precipitated after cooling. Deformability in the hot rolling direction of STS 420J2 martensitic stainless steel was improved because of remaining Cr-C laminates after hot rolling.
