Corrosion Data
Technical Information
The information presented in this bulletin is intended as a guide to the chemical
resistance of materials used in the manufacture of HABONIM Valves.
Many factors which influence corrosion rating, such as temperature fluctuations,
concentration and aeration of fluids, high velocity or abrasions in the fluid stream,
have been taken into account. The physical properties of a material are affected
differently by each corrosive media and it is sometimes necessary to sacrifice
valves with one property to gain a maximum resistant valve with another property.
An "A" rating is associated with internal moving parts, in direct contact with the
media. in some cases a "B" rating can be given to body material in direct contact
with media if the corrosion rate is not such as to cause any serious problem.
Rating Explanation
A / Excellent B / Good C / Poor D / Do not use
Blank = No information available
Ratings are based on media at room temperatures unless otherwise specified.
We advise that ratings given be used as a guide to the selection of valve materials
and not as an absolute recommendation.
Although most of the suggested ratings in the corrosion data chart are based on
experience, Habonim cannot accept responsibility for problems arising from use of
this data.
We do however recommend that in critical applications, tests will be conducted to
verify the rating.
