Materials selection - some considerations
EconomicsEnvironmentalPoliticalMarketAestheticsMaterial properties
Materials selection - material cost
Relative cost - compared to that of hot rolled ASTM A36 plate (0.29C-1Mn-0.28Si)
(unit wt. basis)
Materials selection - environmental
Health hazardsRecycling
Metals particularly suited to recycling - can be easily sorted, remelted, & shaped
Ceramics usually not recycled - many polymers areComposites difficult to recycle - difficult to separate fibers from matrix
when drawing SS to rod
need lubricant
Materials selection - political
Who writes the specs for contract bids?
Will they specify stainless steel rebar in roads & bridges?
Materials selection - market
