摘要： The present invention provides a steel product which, while minimizing an increase in hardness after forging to ensure machinability and cold workability, is improved, for example, in fatigue strength in its non-hardened portion and is improved, in its hardened portion, in rolling resistance level, antipitting level, abrasion resistance, and fatigue strength. The high strength steel for induction hardening comprises, by mass, carbon (C): 0.5 to 0.7%, silicon (Si): 0.5 to 1.0%, manganese (Mn): 0.5 to 1.0%, chromium (Cr): not more than 0.4%, and sulfur (S): not more than 0.035% with the balance consisting of iron (Fe) and unavoidable impurities, the steel being forged to produce a component at least a part of which is then inductively hardened before use.

摘要： A process for producing a high-cleanliness steel which can produce, without relying upon a high-cost remelting process, steel products having cleanliness high enough to satisfy requirements for properties of mechanical parts used under severe environmental conditions. The production process comprises the steps of: transferring a molten steel produced in an arc melting furnace or a converter to a ladle furnace to refine the molten steel; subjecting the molten steel to circulation-type degassing; and casting the molten steel into an ingot, wherein, in transferring the molten steel to the ladle furnace, a deoxidizer including aluminum and silicon, is added to previously deoxidize the molten steel, that is, to perform tapping deoxidation before refining in the ladle refining furnace.
