Q235 \u00c7elik Nedir (Q235A Q235B Q235C Q235D)<\/h2>\n

Q235 \u00e7eli\u011fi, \u00c7in'de kullan\u0131lan yayg\u0131n bir karbon yap\u0131sal \u00e7elik t\u00fcr\u00fcd\u00fcr. \u00c7in standard\u0131 GB\/T 700, Q235'i d\u00f6rt s\u0131n\u0131fa ay\u0131r\u0131r: Q235A, Q235B, Q235C ve Q235D. Yo\u011funlu\u011fu 7,85 g\/cm\u00b3't\u00fcr. \u00c7ekme mukavemeti 370 ila 500 MPa aras\u0131nda de\u011fi\u015firken, akma mukavemeti 235 MPa'd\u0131r. Bu de\u011ferler, \u00e7ap\u0131 16 mm veya daha az olan \u00e7elik \u00e7ubuklar veya plakalar i\u00e7in ge\u00e7erlidir.

\"Q\", \u00c7ince \"\u5c48\u670d\u70b9\" kelimesinin ilk harfidir ve buna kar\u015f\u0131l\u0131k gelen \u0130ngilizce terim, bir metalin akma noktas\u0131 anlam\u0131na gelen \"Qu Fu Dian \"d\u0131r.<\/p>\n

\"235\", 16 milimetre \u00e7ap\u0131nda \u00e7elik kullan\u0131larak yap\u0131lan testten elde edilen 235 megapaskal minimum akma dayan\u0131m\u0131 de\u011ferini ifade eder.<\/p>\n

Q235 \u00e7eli\u011finin \u00f6zellikleri ve uygulamas\u0131<\/h2>\n

M\u00fchendisler Q235 \u00e7eli\u011fini m\u00fckemmel plastisitesi ve toklu\u011fu ile tan\u0131rlar. Ayr\u0131ca iyi kaynaklanabilirlik ve mukavemete sahiptir. Ayr\u0131ca, so\u011fuk b\u00fckmede iyi performans g\u00f6sterir. Q235 malzemeler genellikle \u00e7e\u015fitli formlarda \u015fekillendirilir. Bunlar aras\u0131nda tel \u00e7ubuklar, yuvarlak \u00e7elik, kare \u00e7elik, yass\u0131 \u00e7elik, a\u00e7\u0131l\u0131 \u00e7elik, I-kiri\u015fler, kanal \u00e7eli\u011fi ve di\u011fer profiller bulunur. \u00c7elik plakalar da Q235 malzemelerden yap\u0131l\u0131r.<\/p>\n

Bu \u00fcr\u00fcnler in\u015faat ve kaynak i\u015flerinde yayg\u0131n olarak kullan\u0131lmaktad\u0131r. Takviye \u00e7ubuklar\u0131, fabrikalar, y\u00fcksek gerilim kuleleri, k\u00f6pr\u00fcler, ara\u00e7lar, kazanlar ve konteynerlerin yap\u0131m\u0131na yard\u0131mc\u0131 olurlar.<\/p>\n

Bunlar\u0131 d\u00fc\u015f\u00fck performansl\u0131 mekanik par\u00e7alar i\u00e7in de kullanabilirsiniz. \u00d6rnek olarak hafif gerilim alt\u0131ndaki \u00e7ubuklar, ba\u011flant\u0131 \u00e7ubuklar\u0131, vidalar, somunlar, bur\u00e7lar, destekler ve braketler verilebilir.<\/p>\n
