Heat treatment
The recommended heat treatment for
Sandvik 13C26 follows the temperature
cycle illustrated in figure 3.
During heating [1], or austenitising, the
ferrite is transformed into austenite and
the carbides are partly dissolved. Because
of the carbide dissolution, the contents of
carbon and chromium in the matrix
increase. The subsequent quenching to
room temperature [2] will transform most
of the austenite into martensite. During
