  • Base material for high temperature alloy and manufacture method thereof
    Patent number: 9309584
    Abstract: The present invention relates to a base material for high temperature alloy and a process for manufacturing the same. The base material includes following components (by weight): 10-45% Cr, 0.5-12% Nb, 0.7-2.5% Ti, ?9.0% Mo, ?8.0% W, ?2% Mn, ?1.0% Si, ?2.0% Al, ?0.5% C, ?0.032% O, ?0.032% N,?0.01% S, ?0.02% P, and balance being Fe and unavoidable impurities. The process for manufacturing the base material for high temperature alloy includes following steps: providing raw materials according to the target composition; charging the raw materials in a crucible uniformly layer and layer according to a certain sequence, smelting in vacuum condition; after the materials being melted completely, holding the melt at a temperature; and casting ingot, and cooling to obtain a base material for high temperature alloy.
