\u00d6zellikleri Stellite 21 Tozu<\/a><\/strong><\/h2>\n\n\n\n
    \n
  1. A\u015f\u0131nma Direnci<\/strong>: Kobalt bazl\u0131 olmas\u0131 sayesinde, Stellite 21 tozu m\u00fckemmel a\u015f\u0131nma direnciyle bilinir. A\u015f\u0131nmaya, s\u00fcrt\u00fcnmeye ve erozyona kar\u015f\u0131 iyi dayan\u0131r, bu da onu y\u00fcksek a\u015f\u0131nma uygulamalar\u0131 i\u00e7in m\u00fckemmel k\u0131lar.<\/li>\n\n\n\n
  2. Korozyon Direnci<\/strong>: Y\u00fcksek krom i\u00e7eri\u011fi, ala\u015f\u0131m\u0131n k\u00fck\u00fcrt ve klor i\u00e7erenler de dahil olmak \u00fczere kimyasal olarak agresif ortamlarda bile korozyona kar\u015f\u0131 diren\u00e7 g\u00f6stermesini sa\u011flar.<\/li>\n\n\n\n
  3. Y\u00fcksek S\u0131cakl\u0131k Kararl\u0131l\u0131\u011f\u0131<\/strong>: Stellite 21 tozunun benzersiz \u00f6zelliklerinden biri, y\u00fcksek s\u0131cakl\u0131klarda (950\u00b0C'ye kadar) sertli\u011fini ve mukavemetini koruma yetene\u011fidir. Bu \u00f6zellik onu t\u00fcrbin motoru bile\u015fenleri ve \u0131s\u0131 e\u015fanj\u00f6rleri i\u00e7in olduk\u00e7a arzu edilir hale getirir.<\/li>\n\n\n\n
  4. Tokluk ve Sertlik Dengesi<\/strong>: K\u0131r\u0131lgan olma e\u011filiminde olan baz\u0131 daha sert malzemelerin aksine, Stellite 21, darbe stresleri alt\u0131nda dayan\u0131kl\u0131l\u0131k sa\u011flayan tokluk ve sertlik aras\u0131nda iyi bir denge kurar.<\/li>\n<\/ol>\n\n\n\n
