Os a\u00e7os especiais resistentes ao desgaste com dureza 400 HB, 450 HB, 500 HB, 550 HB, 600 HB proporcionam elevados n\u00edveis de resist\u00eancia ao desgaste mec\u00e2nico e s\u00e3o adequados para componentes expostos a forte abras\u00e3o em casos de utiliza\u00e7\u00e3o como dispositivos de carga, p\u00e1s de rodas, carregadoras, carro\u00e7arias de vag\u00f5es basculantes, transportadores, componentes de escavadoras, m\u00e1quinas rodovi\u00e1rias, crivos e trituradores. A gama de chapas de a\u00e7o martens\u00edtico de alta dureza e baixa liga tem uma resist\u00eancia excecional ao desgaste especialmente abrasivo - tipicamente tr\u00eas a seis vezes superior \u00e0 dos a\u00e7os de constru\u00e7\u00e3o cl\u00e1ssicos.<\/p>

As chapas fabricadas s\u00e3o de gr\u00e3o fino fundido e podem conter elementos de microliga\u00e7\u00e3o como Nb e V. O n\u00edvel mais elevado de dureza \u00e9 obtido por t\u00eampera direta (arrefecimento acelerado diretamente ap\u00f3s a laminagem a quente) ou por t\u00eampera convencional. A pedido, s\u00e3o fornecidos valores garantidos para a energia de impacto do entalhe.<\/p>

Devido \u00e0 sua composi\u00e7\u00e3o qu\u00edmica, as placas resistentes ao desgaste s\u00e3o adequadas para a soldadura. Podem ser utilizados todos os m\u00e9todos de soldadura por fus\u00e3o testados, mas a soldadura por arco com prote\u00e7\u00e3o de g\u00e1s inerte met\u00e1lico provou ser especialmente eficaz (baixo teor de hidrog\u00e9nio). Por raz\u00f5es de preven\u00e7\u00e3o de fissuras, devem ser utilizados el\u00e9ctrodos revestidos de base com um teor de hidrog\u00e9nio controlado para a soldadura manual por arco el\u00e9trico. Antes da soldadura, os el\u00e9ctrodos devem ser secos de acordo com as instru\u00e7\u00f5es do fabricante.<\/p>

Algumas das marcas conhecidas dos fabricantes de placas resistentes ao desgaste\/abras\u00e3o s\u00e3o HARDOX, DUROSTAT, RELIA, CREUSABRO, ABREX, ASTRALLOY, EVERHARD, RAEX, QUARD, FORA.<\/p>
