AISI 431 \/ (1. 4057) \/ AMS 5628<\/h3>\n

AISI 431, martenzitik paslanmaz \u00e7elik s\u0131n\u0131f\u0131nda yer alan, y\u00fcksek dayan\u0131kl\u0131l\u0131k ve a\u015f\u0131nma direnci sunan bir ala\u015f\u0131md\u0131r. AISI 431 \u00e7eli\u011fi, krom, nikel ve mangan ala\u015f\u0131m elementleri i\u00e7erir, bu da ona y\u00fcksek sertlik, daha iyi korozyon direnci ve y\u00fcksek \u00e7ekme dayan\u0131m\u0131 sa\u011flar.<\/p>\n

KOROZYON DAYANIMI: P<\/strong>aslanmaz \u00e7elik kalitesinin korozyon<\/a>a dayan\u0131m\u0131 bir\u00e7ok ortam i\u00e7in gayet iyi bir seviyededir. Bu malzeme X20Cr13 (AISI 420<\/a>) kaliteye oranla \u00e7ok daha iyi bir paslanmazl\u0131k direncine sahiptir ve hem sertlik hem de paslanma direnci istenen ortamlarda s\u0131kl\u0131kla tercih edilebilmektedir.<\/p>\n

KAYNAK YAPILAB\u0130L\u0130RL\u0130K:\u00a0<\/strong>4057 kalite malzemeye kaynak yap\u0131lmas\u0131 fazla tavsiye edilmez ancak baz\u0131 durumlarda malzemeye kaynak i\u015flemi uygulanabilir.<\/p>\n

\u0130\u015eLENEB\u0130L\u0130RL\u0130K:\u00a0<\/strong>Malzemenin ham hali bile \u0131s\u0131l i\u015flemlidir ve y\u00fczey sertlik de\u011feri (fabrikadan gelmi\u015f malzemelerin bile) min 30-32 HRC civar\u0131ndad\u0131r. Dolay\u0131s\u0131yla sert ve mukavemet y\u00fcksek bir malzemedir ve i\u015flemesi di\u011fer paslanmazlara g\u00f6re biraz daha zor olabilir.<\/p>\n

ISIL \u0130\u015eLEM:\u00a0<\/strong>431 paslanmaz \u00e7elik hem krom hem de nikel i\u00e7eren bir paslanmaz \u00e7elik kalitesidir. 431 kalite paslanmaz \u00e7elik \u0131s\u0131l i\u015flemle birlikte kopmaya kar\u015f\u0131 direnci \u00e7ok y\u00fcksek hale getirilebilen bir paslanmaz \u00e7elik t\u00fcr\u00fcd\u00fcr.<\/p>\n

KULLANIM ALANLARI:\u00a0<\/strong>431 kalite paslanmaz \u00e7elikler civata ve somun yap\u0131m\u0131nda, pervane \u015faftlar\u0131nda, pompa \u015faftlar\u0131nda, mikser \u00e7ubuklar\u0131nda, marin te\u00e7hizatlar\u0131nda ve laboratuvar ekipmanlar\u0131nda kullan\u0131lmaktad\u0131r.<\/p>\n

AISI 431, martenzitik paslanmaz \u00e7elik s\u0131n\u0131f\u0131nda yer al\u0131r ve y\u00fcksek sertlik, a\u015f\u0131nma direnci, y\u00fcksek \u00e7ekme dayan\u0131m\u0131 ve korozyon direnci gerektiren uygulamalar i\u00e7in ideal bir malzemedir.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t
