The invention discloses a high temperature resistant deformation resistance cast steel material. Its features are that it adopts Cr, Ni, and Fe as main material, Ta, Nb, C as additive whose optimal proportioning are orderly Cr 30%, Ni 10%, Fe 53%, Ta 0.5%, Nb 0.3%, C 4%, and W 2%. The produced cast steel material has cast out 500 sets of boat pans to apply in production for 200 days. Compared with other material boat pan, it has better performance, and save investment cost 193 RMB per set. Thus the invention has smart conceive and great generalization value. |
