Abstract: A cemented carbide for a flow component for controlling the pressure and flow of well products includes in wt %: about 7 to about 9 Co; about 5 to about 7 Ni; about 19 to about 24 Ti C; about 1.5 to about 2.5 Cr3C2; about 0.1 to about 0.3 Mo and balance of WC. A cemented carbide for fluid handling components and seal ring a comprises in wt %: about 1 to about 30 Ti C; about 12 to about 20 Co+Ni; about 0.5 to about 2.5 Cr; about 0.1 to about 0.3 Mo and balance of WC. A cemented carbide for fluid handling components and seal ring a comprises in wt %: about 15 to about 30 Ti C; about 5 to about 20 Ni; about 0.5 to about 2. Cr; about 0.5 to about 2.5 Mo and balance of WC.

Abstract: A cemented carbide for fluid handling components or a seal ring has a composition in wt %; about 7-11 Ni; about 0.5-2.5 Cr3C2; and about 0.5-1 Mo; and a balance of WC, with an average WC grain size greater than or equal to 4 ?m.

Abstract: A friction stir welding tool for welding of metallic plates and especially steel plates. The friction stir welding tool is made of cemented carbide comprising WC grains in a binder phase and wherein the welding tool is at least partly coated with a surface coating comprising Al2O3.

Abstract: A cemented carbide tool containing tungsten carbide, titanium carbide, niobium carbide, possibly TaC, cobalt, chromium and possibly nickel, iron, molybdenum is disclosed. The composition of the materials provides a lighter material than usual, combined with a good resistance to corrosion as well as high hardness and wear resistance. These properties are particularly interesting for the manufacture of punch tools for cold forming operations. Cold forming tools made with these materials will have much better performance, particularly more steady performance and much longer lifetime. A method of cold forming and drawing, particularly deep drawing and ironing process of aluminum and steel beverage can manufacturing, is also disclosed.
