AISI **4, etc.
Application: Used in Sintering,Brazing, pharmacy, drying, chemical, Glass Industry, electric, high temperature equipment, heat treating, transit Baking Industry and Food Processing, etc.
Material Selection :
SS **9 : With a relatively high chromium content of *5%, this alloy provides good oxidation resistance up to ***0°F(**7°C). Due to instability of the scale formed on this alloy under some conditions, its primary value is in applications where the environment is destructive to high nickel alloys. In these applications where sulphur, lead or zinc may be present, it is particularly useful by virtue of its high chromium content and low nickel content. It also is subject to carbide precipitation in the **0°F(**6°C) to ***0°F(**6°C) range and a low carbon or stabilized alloy should be used where the environment is ***0°F range and a low carbon or stabilized alloy should be used where the environment is corrosive.
AISI **0 : This alloy is quite similar to Type**4 except for a lower silicon content. It is used primarily where a relatively high chromium and nickel content is needed and the belt must withstand moist corrosion.
AISI **4 : This alloy is extensively used for belts operating at temperatures up to ***0°F(***9°C). Its composition provides a high degree of oxidation resistance at high temperatures and good carburization resistance.
