Wear resistant alloy

Abstract

In order to provide a material of low cost that is suitable to produce parts or coatings having a high wear and also high chemical resistance, an alloy is proposed comprising 13 to 16 percent by weight nickel (Ni), 13.5 to 16.5 percent by weight of chromium (Cr), 0.5 to 3 percent by weight of molybdenum (Mo), 3.5 to 4.5 percent by weight of silicon (Si), 3.5 to 4 percent by weight of boron (B) and 1.5 to 2.1 percent by weight of carbon (C), balance iron (Fe).

1 . A material comprising an alloy containing
 13 to 16 percent by weight nickel (Ni),   13.5 to 16.5 percent by weight of chromium (Cr),   0.5 to 3 percent by weight of molybdenum (Mo),   3.5 to 4.5 percent by weight of silicon (Si),   3.5 to 4 percent by weight of boron (B) and   1.5 to 2.1 percent by weight of carbon (C), and   a balance of the alloy comprising iron (Fe).   
     
     
         2 . A material according to  claim 1 , wherein the alloy contains no elements other than Ni, Cr, Mo, Si, B, C and Fe, except impurities. 
     
     
         3 . A material according to  claim 1 , wherein the alloy has a composition of
 13 to 14 percent by weight of nickel (Ni),   14 to 16 percent by weight of chromium (Cr),   1 to 3 percent by weight of molybdenum (Mo),   3.5 to 4.5 percent by weight of silicon (Si),   3.5 to 4 percent by weight of boron (B),   1.8 to 2.1 percent by weight of carbon (C) and   0.2 to 0.5 percent by weight of copper (Cu), and   the balance being of iron (Fe).   
     
     
         4 . A material according to  claim 1 , wherein the alloy has a hardness of less than 60 HRC. 
     
     
         5 . A material according to  claim 1 , wherein the alloy has a melting point of less than 1150° C. 
     
     
         6 . A material according to  claim 1 , wherein the alloy is a powder or a wire or the alloy is a coating on a metal substrate. 
     
     
         7 . A material according to  claim 1 , wherein the alloy is free from preformed hard particles. 
     
     
         8 . A material according to  claim 1 , wherein the alloy contains less than 1 percent of weight of vanadium.
