Kaixin produces a variety of tool and die steel billets of H13 (4Cr5MoSiV1), H11, 5CrNiMo, and 521 grades. They are produced with an electric arc or ladle-refining furnace, an 'RH' or vacuum degassing furnace, and a continuous or ingot casting process flow, followed by electro-slag re-melting for refining. The special steel thus produced has high purity, good combination and isotropic properties, fatigue resistance, and long life. They have been awarded a provincial prize for technological advancement and are widely used in manufacturing of mandrels, dies and rollers.
