Paslanmaz \u00c7elik Vida Performans Standartlar\u0131na Giri\u015f<\/h2>\n

Paslanmaz \u00e7elik vidalar, denizcilik, kimyasal i\u015fleme ve g\u0131da ekipmanlar\u0131 gibi korozyon direnci gerektiren end\u00fcstrilerde vazge\u00e7ilmez ba\u011flant\u0131 elemanlar\u0131d\u0131r. Bu makale, ISO 3506 veya GB\/T 3098.6 gibi standartlarda yer alan boyutlar hari\u00e7 olmak \u00fczere, \u00f6stenitik paslanmaz \u00e7elik SUS304 ve SUS316'dan \u00fcretilen vidalar i\u00e7in mekanik performans standartlar\u0131n\u0131 detayland\u0131rmaktad\u0131r. Ba\u015fl\u0131ca \u00f6zellikler aras\u0131nda malzeme bile\u015fimi, \u00e7ekme dayan\u0131m\u0131 (\u00e7ekme kuvvetlerine dayanma yetene\u011fi), tork (k\u0131r\u0131lmadan \u00f6nceki burulma dayan\u0131m\u0131), akma gerilimi (kal\u0131c\u0131 deformasyon olmadan y\u00fck), akma dayan\u0131m\u0131 (plastik deformasyon noktas\u0131) ve ilgili \u00f6l\u00e7\u00fcmler yer almaktad\u0131r.<\/p>\n

Bu standartlar, ISO 3506 ve \u00c7in GB\/T 3098.6 gibi uluslararas\u0131 normlardan t\u00fcretilmi\u015ftir ve burada m\u00fchendisler, tedarik uzmanlar\u0131 ve yeni ba\u015flayanlar i\u00e7in basitle\u015ftirilmi\u015ftir. Kesin test protokolleri i\u00e7in GB\/T 3098.6-2014 gibi resmi belgelere ba\u015fvurunuz.

Malzeme Bile\u015fimleri: SUS304 ve SUS316<\/h2>\n

SUS304 ve SUS316, m\u00fckemmel korozyon direnci sunan, vidalar i\u00e7in en yayg\u0131n \u00f6stenitik paslanmaz \u00e7eliklerdir. SUS304 genel ortamlar i\u00e7in uygundur, SUS316 ise molibden ilavesi sayesinde klor\u00fcr a\u00e7\u0131s\u0131ndan zengin ortamlarda \u00fcst\u00fcn diren\u00e7 sa\u011flar. 304L (d\u00fc\u015f\u00fck karbonlu) veya 316L gibi di\u011fer varyantlar kaynaklanabilirlik i\u00e7in kullan\u0131l\u0131r ancak standart vidalarda daha az yayg\u0131nd\u0131r.<\/p>\n

201 veya 668 serisi gibi yan\u0131lt\u0131c\u0131 malzemelerden ka\u00e7\u0131n\u0131n; bunlar ger\u00e7ek \u00f6stenitik kalitelerin korozyon direncine sahip de\u011fildir. SUS410 gibi martensitik kaliteler, paslanmaz demir kategorisine girdikleri i\u00e7in burada ele al\u0131nmam\u0131\u015ft\u0131r.<\/p>\n

Ba\u015fl\u0131ca farkl\u0131l\u0131klar: SUS316 daha y\u00fcksek nikel (10-14%), krom (16-18%) i\u00e7eri\u011fine sahiptir ve 2-3% molibden i\u00e7erir, bu da korozyon direncini art\u0131r\u0131r.<\/p>\n

      Tork (k\u0131r\u0131lma torku), ar\u0131zas\u0131z montaj i\u00e7in kritik \u00f6neme sahiptir. GB\/T 3098.6 standartlar\u0131, \u00e7e\u015fitli boyut ve kaliteler i\u00e7in minimum k\u0131r\u0131lma torku de\u011ferlerini sa\u011flar.<\/p>\n
