"burner nozzle material"

Question:

"Could you please suggest a suitable material to manufacture a coal burner nozzle used in a kiln of a cement plant. The current practice is to use AISI 310 grade material I am recommending a tool steel containing 20%Cr,2%C, 1.5%W,0.6%Va as the customer is encountering severe abrasive wear, My apprehension is will this material withstand thermal shock, spalling etc? If you have any thing else to suggest most welcome."
