HIGH-STRENGTH QUENCHED FORMED BODY WITH GOOD CORROSION RESISTANCE AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>A high-strength quenched formed body containing a layer on the surface of an after-quenching formed-body steel material in which layer Zn is a major component and which layer contains 30% by mass or less of Fe, and which layer is present in an amount of 30 g/m2 or more. A quenched formed body is produced by quenching a zinc-plated steel material which includes a zinc-plated layer containing each of Al and Si having alloying-retarding function and readily-oxidizing function independently or compositely, in an amount of 0.15% by mass or more, after heating it to 800° C. or more and 950° C. or less in an oxidizing atmosphere containing 0.1% by volume or more of oxygen.</p> |
