NITRONIC 60 Plate, Alloy 218 Sheet, UNS S21800 Plate, AMS 5848 Nitronic 60 Plates

Nitronic 60 Plate is truly an all purpose metal. Alloy 218 Sheet was originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.S. UNS S21800 Plate is best known for its wear and galling resistance.

The additions of Silicon and Manganese have given Nitronic 60 Plate a matrix to inhibit wear, galling, and fretting even in the annealed condition. Higher strengths are attainable through cold working the material and is still fully austenitic after severe cold-working. This working does not enhance the anti-galling properties as is normal for carbon steels and some stainless steels. The benefit to the cold or hot work put into the material is added strength and hardness, and the wear resistance does not decrease noticeably. Chromium and Nickel additions give AMS 5848 Nitronic 60 Plate comparable corrosion to 304 and 316 stainless steels, while having approximately twice the yield strength. The high mechanical strength in annealed parts permits use of reduced cross sections for weight, and cost reductions through the use of thinner stock.
