3.1<br />
Material selection<br />
The following decision chart provides guidance on the<br />
selection of the appropriate <strong>deva</strong>.<strong>metal</strong> ® alloy according<br />
to the environmental conditions of the application.<br />
Is the operating<br />
temperature > 350 °C?<br />
DEVA ®<br />
bronze alloys<br />
DEVA ® iron or<br />
iron/nickel alloys<br />
Materials<br />
Will the material be<br />
chemically attacked?<br />
Operating<br />
temperature<br />
> 200 °C?<br />
Is corrosion a<br />
problem?<br />
Use<br />
bronze alloys<br />
Use<br />
bronze alloys<br />
heat treated<br />
Use iron or<br />
iron/nickel alloys<br />
Use nickel alloys or<br />
stainless steel<br />
