| Title | HIGH-TEMPERATURE RESISTANT AUSTENITIC STAINLESS STEEL |
| Abstract | The purpose of the present invention is to provide a high-temperature resistant austenitic stainless steel, with which resistance to oxidation at high temperature can be obtained through formation of alumina scale, and with which good productivity is ensured. This austenitic stainless steel contains 10-30 wt% of Ni, 10-25 wt% of Cr, 0.01-0.1 wt% of at least one element selected from the group consisting of Zr, Hf, Y, and La, 4.2-8.5 wt% of Cu, and less than 6 wt% of Al, the remainder being Fe. |
| Scope of claims |
(In Japanese)[請求項1] Niを10～30重量％、Crを10～25重量％、Zr、Hf、Y及びLaからなる群より選択される少なくとも一種を0．01～0．1重量％、Cuを4．2～8．5重量％並びにAlを6重量％未満含有し、残部としてFeを含有する、高耐熱オーステナイト系ステンレス鋼。 [請求項2] Alを2重量％以上6重量％未満含有する、請求項1記載の高耐熱オーステナイト系ステンレス鋼。 |
