12% cr steel Introduction
AG8 官网 - steel-grades
A typical steel is FV 448, an 11% Cr, 0.6% Mo, 0.25% V, 0.3% Nb steel with good creep resistance up to 550°C. The corrosion and scaling resistances of the latest so-called 'Super 12% Cr' steels are at least equal to those of the simple 12% Cr steels and in many cases significantly better.
