When should you go through this mill?
You go to the mill when volume and lead time allow it — on the order of a container, sometimes less, with a horizon of a few months, shipping included. We make that call: when buying at the source works out cheaper for you, we tell you.
As soon as the specification moves beyond plain 304L/316L: 316Ti, 321/H, duplex. And for U-tubes.
