Aralar\u0131ndaki fark\u0131n Ti ve Nb ilavesi oldu\u011funu g\u00f6rebiliriz. Stabilize element titanyumun eklenmesi nedeniyle 321, 426\u00b0C~815\u00b0C'de krom karb\u00fcr olu\u015fumuna direnebilir, bu nedenle m\u00fckemmel tanecikler aras\u0131 korozyon direncine ve y\u00fcksek s\u0131cakl\u0131k performans\u0131na sahiptir ve 304 ve 304L'den daha y\u00fcksek s\u00fcr\u00fcnme ve gerilim k\u0131r\u0131lma \u00f6zelliklerine sahiptir.

347 Paslanmaz \u00e7elik, niyobyum i\u00e7eren \u00d6stenitik paslanmaz \u00e7eliktir ve 347H, bunun y\u00fcksek karbonlu versiyonudur. 347, 304'e dayanan niyobyum ilaveli bir versiyon olarak g\u00f6r\u00fclebilir. Nadir bir toprak elementi olan Nb, tanelerin rafine edilmesinde titanyuma benzer bir etkiye sahiptir, tanecikler aras\u0131 korozyona direnebilir ve ya\u015flanma sertle\u015fmesini destekleyebilir.<\/p>\n
