delayed quenchingとは 意味・読み方・使い方

To provide a method for producing a steel sheet for heat treatment which gives a steel member excellent in all of good workability and quenching property and also, fatigue characteristics, toughness and delayed fracture characteristics.例文帳に追加

加工性及び焼入性が良好であると共に、疲労特性、靭性及び遅れ破壊特性の全てに優れた鋼部材を与える熱処理用鋼板の製造方法を提供する。 - 特許庁

Since high strength bolt steel is used as common rail base material 18, surface hardness can be increased by just quenching and tempering without carburizing, inner pressure fatigue strength of inner walls of the main pipe 11 and the branch tube part 12 can be secured, and deterioration of resistance against delayed fracture of the external thread part 13 can be avoided although hardness is very high.例文帳に追加

コモンレール素材１８として高強度ボルト用鋼を用いたので、浸炭処理を施さずに、単に焼入れ焼戻し処理を行うだけで、表面の硬度が高められ、主管１１と分岐用筒部１２の内壁における内圧疲労強度が確保されるとともに、硬度が高くても雄ネジ部１３における耐遅れ破壊性の低下が回避される。 - 特許庁
