摘要
ASTM D-grade steels with 12% Cr and 1. 5 to 2. 3% C are widely used for tools in metal forming and mineral processing. By adding Nb to Ti up to 7 vol% of MC carbides are precipitated and the performance of the tools is improved. This article examines the microstructural background of the new tool steels, their production and properties.
