Definition - What does Dimensional Stability mean?
Dimensional stability refers to the physical property of a metal that is representative of its ability to maintain its original boundaries and structural integrity while in use for a given application. Dimensional stability is often indirectly proportional to corrosion rates in the metal.
Metals with good dimensional stability are tough and rigid with minimal response to wear and tear over prolonged periods of use. This is characterized by maintenance of its original pleating and shape, with minimal shrinkage or plasticity.
Corrosionpedia explains Dimensional Stability
The dimensional stability of a metal refers to any observed change in size or composition when it is used or reprocessed. This is often due to the characteristics of the metal and the rate of thermal contraction force due to processing.
Dimensional stability may be improved by the following:
- Reduction of double-end dipping to fit into galvanizing baths
- Use of symmetrical sections
- Use of sections of near equal thickness at joints
- Accurately preform parts to avoid restraints during joining
- Continuous weld joints
