[TR] Stainless Steel

[DAVID MASSEY]

 They make stainless pots and pans with aluminum inserts.  These are forged together using various processes.  It is possible that they are forging flat plates of stainless and mild steel and then punching and forming bumpers out of that sandwich.  Stainless steel has a reputation of being difficult to machine and this may explain why they would go to the trouble of forging a thin layer or stainless on a more easily machinable soft steel.
On the other hand, they say "100% stainless steel grade 304 , thickness 1.5mm"   If that were the case why paint the inside with three coats of paint?  Me thinks they are lying.
