Ba\u015fl\u0131ca amac\u0131, m\u00fchendislerin, tasar\u0131mc\u0131lar\u0131n ve \u00fcreticilerin denizcilik, kimyasal i\u015fleme ve y\u00fcksek s\u0131cakl\u0131k ortamlar\u0131 gibi \u00e7e\u015fitli \u00e7evresel ko\u015fullar alt\u0131nda y\u00fcksek korozyon direnci, mukavemet ve dayan\u0131kl\u0131l\u0131k gerektiren uygulamalar i\u00e7in uygun ba\u011flant\u0131 elemanlar\u0131n\u0131 se\u00e7melerine yard\u0131mc\u0131 olmakt\u0131r.<\/p>\n

Bu bile\u015fimler, uyumluluk ve g\u00fcvenilirli\u011fi sa\u011flamak i\u00e7in ISO kodlar\u0131, ilgili ba\u011flant\u0131 eleman\u0131 gruplar\u0131 ve ilgili standartlarla \u00e7apraz referansland\u0131r\u0131lm\u0131\u015ft\u0131r. \u00d6rne\u011fin, paslanmaz \u00e7elikten yap\u0131lm\u0131\u015f c\u0131vata, vida ve saplamalar i\u00e7in GB\/T 3098.6'dan, somunlar i\u00e7in GB\/T 3098.15'ten ve \u00f6zel uygulamalar i\u00e7in di\u011fer standartlardan yararlan\u0131r.<\/p>\n

Pratik a\u00e7\u0131dan bak\u0131ld\u0131\u011f\u0131nda, bu k\u0131lavuz, \u00e7ekme dayan\u0131m\u0131, akma dayan\u0131m\u0131 ve taneler aras\u0131 korozyona kar\u015f\u0131 diren\u00e7 gibi \u00f6zellikleri art\u0131ran bile\u015fimleri belirterek malzeme ar\u0131zas\u0131yla ili\u015fkili riskleri azaltmaya yard\u0131mc\u0131 olur.
