Kulutusta kest\u00e4v\u00e4t erikoister\u00e4kset, joiden kovuus on 400 HB, 450 HB, 500 HB, 550 HB ja 600 HB, kest\u00e4v\u00e4t hyvin mekaanista kulumista ja soveltuvat komponentteihin, jotka altistuvat voimakkaalle kulutukselle esimerkiksi lastauslaitteissa, py\u00f6r\u00e4kauhoissa, kuormaajissa, kauhavaunujen rungoissa, kuljettimissa, kaivinkoneiden osissa, tiekoneissa, seuloissa ja murskaimissa. Korkean kovuuden omaavien, matalaseosteisten martensiittisten ter\u00e4slevyjen valikoima kest\u00e4\u00e4 erinomaisesti erityisesti hankaavaa kulutusta - tyypillisesti kolmesta kuuteen kertaa paremmin kuin perinteiset rakennuster\u00e4kset.<\/p>

Valmistettavat levyt ovat hienorakeisia, ja ne voivat sis\u00e4lt\u00e4\u00e4 mikrosulamia, kuten Nb:t\u00e4 ja V:t\u00e4. Korkeampi kovuus saavutetaan suoralla sammutuksella (nopeutettu j\u00e4\u00e4hdytys suoraan kuumavalssauksen j\u00e4lkeen) tai tavanomaisella sammutuksella. Pyynn\u00f6st\u00e4 toimitetaan takuuarvot loven iskuenergialle.<\/p>

Kemiallisen koostumuksensa ansiosta kulutusta kest\u00e4v\u00e4t levyt soveltuvat hyvin hitsaukseen. Kaikkia testattuja sulahitsausmenetelmi\u00e4 voidaan k\u00e4ytt\u00e4\u00e4, mutta erityisen tehokkaaksi on osoittautunut suojakaarihitsaus suojakaasulla (v\u00e4h\u00e4inen vetypitoisuus). Halkeamien ehk\u00e4isemiseksi k\u00e4sik\u00e4ytt\u00f6isess\u00e4 valokaarihitsauksessa olisi k\u00e4ytett\u00e4v\u00e4 em\u00e4sp\u00e4\u00e4llystettyj\u00e4 elektrodeja, joiden vetypitoisuus on hallittu. Ennen hitsausta elektrodit on kuivattava valmistajan ohjeiden mukaisesti.<\/p>

Joitakin tunnettuja kulumista\/kulumista kest\u00e4vien levyjen valmistajien tuotemerkkej\u00e4 ovat HARDOX, DUROSTAT, RELIA, CREUSABRO, ABREX, ASTRALLOY, EVERHARD, RAEX, QUARD ja FORA.<\/p>
