Daily briefing: 330 is not 304
Furnace baskets are N08330. Washdown is 304 or 316. Mixing them is how the first oven cycle fails.
304 is wet service. 316 is chlorides. 330 is furnace air. “Stainless wire basket” without a grade is not a structure spec. Heat-treat fixtures in this shop are 330 until the print names a nickel alloy.
