專利摘要(中)
本發明主要揭示一種經由熔解及凝固所得之高強度耐腐蝕鐵鉻合金塊材，其硬度係大於HV400，且其組成以重量百分比計係包括：30~68％的Cr、1.5~8％的Ni、1.6~6％的C、以及平衡量的F e和不可避免之雜質；其中，5≦Fe/Ni≦10，且10≦Cr/C≦33。實驗數據顯示，本發明之高強度耐腐蝕鐵鉻合金塊材的多個樣品的硬度皆高於HV400，同時亦因高Cr含量而具有高耐腐蝕能力。因此，實驗數據證實，本發明之高強度耐腐蝕鐵鉻合金塊材係能夠取代習用的高強度不銹鋼，進而應用於各種工業領域之中，例如：航空、運輸、海洋設施零組件、化工設備及管件、發動機零件、渦輪葉片、閥門、軸承、建材、運動器材等。

專利摘要(英)
The present invention discloses a high strength and corrosion resistant ferrochrome alloy bulk produced by sequentially applying a melting process and a solidification process to a virgin material. The high strength and corrosion resistant ferrochrome alloy bulk comprises, in weight percent: 30-68％ Cr, 1.5-8％ Ni, 1.6-6％ C, and the balance Fe and incidental impurities, and additionally Fe/Ni is between 5 to 10 and Cr/C is between 10 to 33. Experimental data reveal that, samples of the high strength and corrosion resistant ferrochrome alloy bulk all possess hardness above HV400 and high corrosion resistance due to the high content of Cr. As a result, experimental data have proved that the high-strength and corrosion-resistant ferrochrome alloy bulk of the present invention can replace conventional high-strength stainless steels, and then be widely applied in various industrial fields, e.g., aviation, transportation, marine facility components, chemical equipment and pipe fittings, engine parts, turbine blades, valves, bearings, building materials, sports equipment and so on.
