ステンレス薄鋼板の温間プレス成形

Warm Press Forming of Stainless Steel Sheets

野原 清彦(Kiyohiko Nohara) 小野 寛(Yutaka Ono) 要旨 : ステンレス鋼薄板のプレス成形における絞り性およびリストライク性に対する温間加工の 効果を検討した。その結果,材料の成分調整と温間加工条件の適正な選択によって,オース テナイト系およびフェライト系ともプレス成形性は著しく向上することがわかった。新し く開発した水溶性の耐熱性潤滑材を使用することにより,ステンレス鋼の温間成形法の実 用化の目途を得た。とくに本法の適用により,従来の室温プレス成形時に問題となるオース テナイト系の置割れおよびフェライト系のリジングの現象が回避もしくは軽減されること がわかった。 Synopsis :

The effect to "warm press forming" on the press formability of stainless steel sheets in deep drawing and restriking was studied. The result indicates that the press formability of both austenitic and ferritic steels is markedly improved by the compositional control of materials and the suitable selection of warm press forming conditions. The application of a newly developed heat resisting lubricant which can easily be coated and removed because of being water-soluble is to make industrialization of warm press forming possible. It is noted that the problems of delayed fracture and ridging associated with austenitic and ferritic steels, respectively, during conventional press forming at room temperature can be avoided or reduced by the employment of this press forming technique.
