nodular iron castingとは 意味・読み方・使い方

IMPACT ABSORBING MEMBER OF NODULAR GRAPHITE CAST IRON CASTING, AND MANUFACTURING METHOD FOR THE SAME例文帳に追加

球状黒鉛鋳鉄鋳物製衝撃吸収部材及びその製造方法 - 特許庁

The manufacturing method for the impact absorbing member of a nodular graphite cast iron casting casts a nodular graphite cast iron composition into a material for the impact absorbing member, subjects it to heat treatment for decomposing primary cementite and/or heat treatment for decomposing pearlite and then to blast cleaning using an iron blasting material, and next holds it at 550 to 670°C for one to three hours.例文帳に追加

また球状黒鉛鋳鉄鋳物製衝撃吸収部材の製造方法は、球状黒鉛鋳鉄組成で衝撃吸収部材の素材を鋳造後、一次セメンタイトを分解する熱処理及び／又はパーライトを分解する熱処理を施した後、鉄系ブラスト材でブラスティング清浄を行い、続いて５５０〜６７０℃の温度に１〜３時間保持する。 - 特許庁

The impact absorbing member comprises a nodular graphite cast iron casting provided with a hollow portion, and the surface layer region of the hollow portion has substantially no work-hardened layer and the wall thickness thereof is axially continuously or partly changed.例文帳に追加

衝撃吸収部材は、中空部が形成された球状黒鉛鋳鉄鋳物からなり、中空部の表層部が実質的に加工硬化層を有せず、肉厚が軸方向に沿って連続的又は部分的に変化している。 - 特許庁
