Tool and Special Steel Powder
Tool and Special Steel Powder
Tool steels are known for hardness, wear resistance and heat tolerance, normally retaining alloying elements, Cr, V, Mo and W, for hardness and thermal stability.
It can be used in pressing and sintering, P/M, 3D printing, MIM, spraying and coating etc. For 3D printing, consistent particle size and spherical shape is important for good layer density and minimal defects. For PM application, compressibility and sintering behavior are key.
Tool steel powders also can be used in repair processes. For example, using laser cladding to add material to worn tools.
Invar 36, also known generically as FeNi36, is a nickel–iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or α). The name Invar comes from the word invariable, referring to its relative lack of expansion or contraction with temperature changes. It can be used for LPBF with minimum residual stress.
Kovar is a nickel–cobalt ferrous alloy compositionally identical to Fernico, designed to have substantially the same thermal expansion characteristics as borosilicate glass to allow a tight mechanical joint between the two materials over a range of temperatures. It is applied for glass-to-metal seals in scientific apparatus and conductors.
Our common production process for tool steel and special steel powders includes Gas Atomizing process (GA), Water Atomizing process & Plasma Rotating Electrode Process (PREP).
