AISI 310 (310S)<\/strong> ve AISI 314<\/strong> y\u00fcksek s\u0131cakl\u0131k i\u00e7in \u00fcretilmi\u015f iki \u00f6stenitik paslanmaz \u00e7eliktir. Krom ve nikel oranlar\u0131 birebir ayn\u0131d\u0131r. Aralar\u0131ndaki fark tek bir elementtedir: silisyum<\/strong>.<\/p>\n

Silisyum neden konuyor?<\/h3>\n

Y\u00fcksek s\u0131cakl\u0131kta \u00e7eli\u011fi koruyan \u015fey, y\u00fczeyinde olu\u015fan krom oksit tabakas\u0131d\u0131r. S\u0131cakl\u0131k y\u00fckseldik\u00e7e bu tabaka bir noktadan sonra yetersiz kal\u0131r ve tufallanma ba\u015flar. AISI 314’e eklenen %1,50 – 2,50 silisyum<\/strong>, oksit tabakas\u0131n\u0131 daha diren\u00e7li hale getirir ve tufallanma s\u0131cakl\u0131\u011f\u0131n\u0131 yukar\u0131 ta\u015f\u0131r.<\/p>\n

Kazan\u00e7 somuttur: EN 10095’e g\u00f6re kuru havada s\u00fcrekli servis s\u0131cakl\u0131\u011f\u0131 310S i\u00e7in 1050 °C, 314 i\u00e7in 1150 °C<\/strong>‘dir. Yakla\u015f\u0131k 100 °C’lik bu fark, silisyumun kar\u015f\u0131l\u0131\u011f\u0131d\u0131r.<\/p>\n

Bedeli: k\u0131r\u0131lganl\u0131k<\/h3>\n

Silisyum bedava gelmez. Outokumpu, 1.4841’in (314) 600 – 950 °C aral\u0131\u011f\u0131nda s\u00fcrekli \u00e7al\u0131\u015fmada k\u0131r\u0131lganla\u015fmaya y\u00fcksek yatk\u0131nl\u0131k<\/strong> g\u00f6sterdi\u011fini belirtiyor. Alman Paslanmaz \u00c7elik Enformasyon Merkezi (ISER) ise 1.4841’in 1.4845’ten (310S) daha yatk\u0131n oldu\u011funu, 1.4845’in kendisinin de 600 – 900 °C band\u0131nda k\u0131r\u0131lganla\u015fabildi\u011fini yaz\u0131yor.<\/p>\n

Pratik sonucu \u015fudur: s\u0131cakl\u0131k sabitse ve y\u00fcksekse 314; \u0131s\u0131tma-so\u011futma \u00e7evrimi varsa 310S.<\/strong> ISER, \u00e7evrimli ko\u015fullarda 1.4845’in daha yap\u0131\u015fkan bir oksit kabu\u011fu olu\u015fturdu\u011fu i\u00e7in tercih edildi\u011fini belirtiyor.<\/p>\n
