More Information
Summary:The invention discloses a martensite heat-resisting steel, which is characterized by the following: setting main constituent of the alloy as 0. 05-0. 09 C, 10. 5-12. 0 Cr, 1. 40-1. 80 Ni, 0. 35-0. 50 Mo, 0. 15-0. 25 V, 0. 05-0. 15 Nb, not more than 0. 60 Si, not more than 0. 60 Mn, not more than 0. 020, not more than 0. 030 P, not more than 0. 30 Cu and surplus as Fe. This alloy possesses higher intensity good ductibility and corrosion resistance.
