ferrite decarburized depthとは 意味・読み方・使い方

To provide a method for manufacturing a soft steel stock for spring with excellent cold workability in which ferrite decarburized depth at the surface is practically zero is provided.例文帳に追加

表面のフェライト脱炭深さが事実上ゼロであり、かつ、軟質で冷間加工性に優れたばね用鋼材の製造方法を提供する。 - 特許庁

In the ultrahigh temperature hot forged non-heat-treated part, a steel member having prescribed components is used, the fraction of ferrite is 0.1 to 0.6, the average grain size of ferrite is 10 to 30 μm, and the depth of all decarburized layers is 0.02 to 0.08 mm.例文帳に追加

所定の成分を有する鋼材を用い、フェライト分率０．１〜０．６、フェライト平均粒径１０〜３０μｍ、全脱炭層深さが０．０２〜０．０８ｍｍであることを特徴とする超高温熱間鍛造非調質部品。 - 特許庁

A super-high temperature hot-forged non-tempered product is formed of a steel of predetermined composition, with the ferrite fraction of 0.1-0.6, the ferrite grain size of 20-40 μm, the porosity of 0.2 to ≤ 1.0%, and the full depth of a decarburized layer of 0.02-0.12 mm.例文帳に追加

所定の成分を有する鋼材を用い、フェライト分率０．１〜０．６、フェライト粒径２０〜４０μｍ、空孔率０．２〜１．０％以下、全脱炭層深さが０．０２〜０．１２ｍｍであることを特徴とする超高温熱間鍛造非調質部品。 - 特許庁

At the time of obtaining a spring steel through the stages of quenching and tempering, the quenching temperature of the surface is controlled to below the A3 point, and a decarburized layer essentially consisting of a mixed structure of pro-eutectoid ferrite and sorbite is formed on the surface layer part to a depth of 0.01 to 0.20 mm from the surface.例文帳に追加

焼入れ、焼戻しの工程を経てばね鋼を得るにあたり、表面の焼入れ温度をＡ_３点未満とし、表面から０．０１ｍｍ以上０．２０ｍｍ以下の表層部に、初析フェライトとソルバイトとの混合組織を主体とする脱炭層を形成する。 - 特許庁
