Tools steels:
cannot hold hardness at an elevated temperature
have a carbon content of less than 0.5%
are not very resistant to abrasion
typically contain carbides
typically contain carbides
●The
tool steels have carbon content from 0.5 % to 1.5 %.
●These
steels hold hardness at elevated temperature also and thus, are resistance to
abrasion.
●Tools
steels are alloyed with carbide forming elements.
Hence,
the correct option is (D).
