What pressure will the component experience?
Pressure-containing components require the correct design specification and material condition.
Is the component exposed to chemicals?
The exact chemical environment matters because corrosion resistance varies with chemistry, concentration, temperature and flow conditions.
Is machining required?
If the material will be machined into a finished component, round bar dimensions and machining allowance become important.
What documentation is required?
Industrial projects may require chemical analysis, mechanical test results, heat-treatment information, dimensional inspection or other documentation.
