Kdybych dnes vedl s n\u011bk\u00fdm rozhovor na t\u00e9ma \u201ez\u00e1bradl\u00ed na balkon\u201c a doty\u010dn\u00e1 osoba by se vyj\u00e1d\u0159ila v tom smyslu, \u017ee m\u00e1 na balkon\u011b \u017eelezn\u00e9 z\u00e1bradl\u00ed, z\u0159ejm\u011b bych na to zareagoval a jej\u00ed v\u00fdrok opravil. Ocel je v sou\u010dasn\u00e9 dob\u011b strategickou pr\u016fmyslovou surovinou a sou\u010d\u00e1st\u00ed v\u00fdroby oceli je i ocel nerezov\u00e1. Lze ji identifikovat od ostatn\u00edch typ\u016f oceli pom\u011brn\u011b snadno, nebo\u0165 odolnost v\u016f\u010di korozi je jej\u00ed v\u00fdjime\u010dnou vlastnost\u00ed. Ono je to ale s tou odolnost\u00ed proti korozi pon\u011bkud slo\u017eit\u011bj\u0161\u00ed. Nerezov\u00e1 ocel nekoroduje d\u00edky oxidu chromit\u00e9ho, kter\u00fd vytv\u00e1\u0159\u00ed na jej\u00edm povrchu takzvanou pasivn\u00ed vrstvu. Ta br\u00e1n\u00ed oxidaci kovu a za b\u011b\u017en\u00fdch atmosf\u00e9rick\u00fdch podm\u00ednek v dom\u00e1cnosti i v exteri\u00e9ru v\u00e1m kvalitn\u00ed nerezov\u00e1 ocel korodovat nebude. Tato vrstvi\u010dka se neust\u00e1le obnovuje za p\u0159\u00edtomnosti kysl\u00edku, tak\u017ee pokud byste nerez trochu po\u0161kr\u00e1bali, vrstvi\u010dka se velmi rychle obnov\u00ed d\u00edky p\u0159\u00edtomnosti chromu v dan\u00e9 slitin\u011b.

M\u016f\u017eete se s t\u00edm setkat nap\u0159\u00edklad n\u011bkde v bl\u00edzkosti baz\u00e9n\u016f, kde se pou\u017e\u00edv\u00e1 chlorov\u00e1 chemie.V p\u0159\u00edpad\u011b nerezov\u00e9ho z\u00e1bradl\u00ed ale m\u016f\u017eete b\u00fdt bez starost\u00ed. Nebudete-li jej podrobovat kontaktu s agresivn\u00edmi chemik\u00e1liemi, korodovat by nem\u011blo a m\u011blo by v\u00e1m naopak slou\u017eit mnoho let k va\u0161\u00ed spokojenosti. V takov\u00e9m p\u0159\u00edpad\u011b jej posta\u010d\u00ed pouze \u010distit od mastnoty, t\u0159eba teplou vodou s jarem, jedlou sodou a trochou octa.
