air hardening steelとは 意味・読み方・使い方

To provide a high carbon hot rolled steel sheet to which B is added, and, even if, upon hardening, long time heating is performed in an atmosphere in which air is mixed and carbon potential is controlled, which can stably obtain excellent hardenability, also, has the total elongation El of ≥37%, and has excellent cold workability, and to provide a method for producing the same.例文帳に追加

Bが添加されており、焼入れ処理時に空気を混合してカーボンポテンシャルを制御した雰囲気中で長時間加熱しても安定して優れた焼入れ性が得られ、かつ全伸びElが37%以上で優れた冷間加工性を有する高炭素熱延鋼板およびその製法を提供する。 - 特許庁

Since the jointing sealer 8 is nonaqueous, its hardening is quickened and the repairing work can quickly be executed, and also, since the intrusion of the air from the position of flanges 4 is shut off with the refractory 6 for repairing, the pick-up phenomenon of nitrogen is prevented and the quality of molten steel is improved.例文帳に追加

目地材８が非水系であるため硬化が速くて補修作業を迅速に行うことができ、しかも、フランジ４の箇所からの空気の侵入が補修用耐火物６によって遮断されるため、窒素ピッチアップ現象を防止して溶鋼の品質を向上できる。 - 特許庁
