HEAT TREATMENT SPECIFICATION AND MECHANICAL PROPERTIES:

022Cr17Ni12Mo2 is include molybdenum grade , its totoal performance better than 310 and 304. In high temperature status when H2SO4 concentration under 15% and exceed 85%, the steel have wildely usage. The steel also have good bearing erosive performance of chloride . So usually used in oecan circulation.

Thermostability :

In under 1600℃ interrupted using and under 1700℃ continuous using, the steel have good tolerate oxidizability.

Heat treatment:

Annealing at 1850-2050℃ ,rapid cooling .

Typical usage :

Heat exchanger of pulp and papermaking equipment. dyeing installatoin, film washing equipment, pipeline ,external materials of coastal regions construction.

Austenite structure.
