A co vy? Nev\u00edte? Ferrum, Fe. Ale nic si z toho ned\u011blejte, pokud to u\u017e nev\u00edte. Jen\u017ee v souvislosti s \u017eelezem a ocel\u00ed se pou\u017e\u00edvaj\u00ed zkratky, kter\u00e9 ji\u017e pak nemaj\u00ed s chemi\u00ed mnoho spole\u010dn\u00e9ho. Hlavn\u011b \u010d\u00edseln\u00e9 \u010d\u00e1sti, to kde jsou b\u011b\u017en\u00e9 p\u00edsmenn\u00e9 zkratky v\u011bt\u0161inou vyjad\u0159uj\u00ed, co v onom kuse \u017eeleza \u010di oceli je. Tak\u017ee, p\u0159ece jen ta chemie, i kdy\u017e ne v pln\u00e9 m\u00ed\u0159e. Zku\u0161en\u00fd v\u00fdrobce, pop\u0159\u00edpad\u011b i prodava\u010d se v tom mus\u00ed vyznat a zcela bezpe\u010dn\u011b orientovat.

Pokud se pod\u00edv\u00e1te na celou tu zkratku, tak vypad\u00e1 n\u011bjak takto, 10CrMo9-10, 1.7380, 15313, 10KH2M. V\u00edte o\u010d se jedn\u00e1? Ani asi nem\u016f\u017eete, pokud nejste p\u0159\u00edmo od fochu.
