O\u021belurile speciale rezistente la uzur\u0103 cu duritatea 400 HB, 450 HB, 500 HB, 550 HB, 600 HB ofer\u0103 niveluri ridicate de rezisten\u021b\u0103 la uzura mecanic\u0103 \u0219i sunt potrivite pentru componente expuse la abraziune puternic\u0103 \u00een cazuri de utilizare precum dispozitive de \u00eenc\u0103rcare, lope\u021bi cu ro\u021bi, \u00eenc\u0103rc\u0103toare, caroserii de vagoane basculante cu jgheab, transportoare, componente de excavatoare, utilaje rutiere, ecrane \u0219i concasoare. Gama de pl\u0103ci din o\u021bel martensitic slab aliat, cu duritate ridicat\u0103, are o rezisten\u021b\u0103 remarcabil\u0103 la uzura deosebit de abraziv\u0103 - de obicei de trei p\u00e2n\u0103 la \u0219ase ori mai mare dec\u00e2t o\u021belurile clasice pentru construc\u021bii.<\/p>

Pl\u0103cile fabricate sunt topite cu granula\u021bie fin\u0103 \u0219i pot con\u021bine elemente microaliate precum Nb \u0219i V. Nivelul mai ridicat de duritate este ob\u021binut prin c\u0103lire direct\u0103 (r\u0103cire accelerat\u0103 direct dup\u0103 laminarea la cald) sau prin c\u0103lire conven\u021bional\u0103. La cerere, se furnizeaz\u0103 valori garantate pentru energia de impact a crest\u0103turii.<\/p>

Datorit\u0103 compozi\u021biei lor chimice, pl\u0103cile rezistente la uzur\u0103 sunt potrivite pentru sudare. Pot fi utilizate toate metodele de sudare prin fuziune testate, dar sudarea cu arc protejat cu gaz inert metalic s-a dovedit deosebit de eficient\u0103 (aport redus de hidrogen). Din motive de prevenire a fisurilor, pentru sudarea manual\u0103 cu arc electric trebuie s\u0103 se utilizeze electrozi cu acoperire bazic\u0103 cu con\u021binut controlat de hidrogen. \u00cenainte de sudare, electrozii trebuie usca\u021bi \u00een conformitate cu instruc\u021biunile produc\u0103torului.<\/p>

Unele dintre m\u0103rcile cunoscute ale produc\u0103torilor de pl\u0103ci rezistente la uzur\u0103\/abrasiune sunt HARDOX, DUROSTAT, RELIA, CREUSABRO, ABREX, ASTRALLOY, EVERHARD, RAEX, QUARD, FORA.<\/p>
