In a first aspect the heat resistant stainless steel wire or strip (A) comprises a thin stainless steel wire or strip (2) containing, in addition to chrome, at least one of nickel, aluminum and yttrium. The stainless steel wire or strip (2) is covered with a covering layer (10) formed of nickel group alloy particles (4) containing aluminum covered with ceramic particles (6) or chrome alloy particles (4) containing aluminum covered with ceramic particles (6). The stainless steel wire or strip (2) and covering layer (10) is subjected to a heat treatment under vacuum at a temperature of 1100 to 1300 DEG C. The alloy particles (4) are deposited on the stainless steel wire or strip (2), and the alloy particles (4) and the ceramic particles (6) of the covering layer (10) are bonded to each other. The ceramic particles (6) of the covering layer (10) have an average particle diameter of 1 micron or less and contain at least one of aluminum, silicon, magnesium, zirconium, barium and titanium. In a second apsect the heat resistant stainless steel wire or strip (B) comprises a thin austenitic stainless steel wire or strip (12), as a substrate metal, covered with a first layer (13a) on the outermost surface thereof. The first layer (13a) comprises aluminum and iron-aluminum alloy. A second layer (13b) in which an aluminum-iron compound and an aluminum-nickel compound are dispersed into a ferritic stainless steel mainly comprising iron-chrome forms an intermediate layer. <IMAGE> |
