AISI Type S21800 Stainless Steel, 70% cold reduction
Categories:	Metal; Ferrous Metal; Heat Resisting; Stainless Steel; T S20000 Series Stainless Steel
Material Notes:	Galling and wear resistant, austenitic. Corrosion resistance better than type 304 in most media and pitting resistance superior than type 316. Room temperature yield strength about 2 times type 304. Excellent high-temperature oxidation resistance and low-temperature impact resistance. Applications include valve stems, seats and trim, nuts and bolts, screening, chain drive systems, and pins, bushings, and roller bearings. Test specimens were 11.2 mm diameter at start.
Key Words:	UNS S21800, ASME Code Case 1817, ASTM A193 (grade B8S), ASTM A194 (grade 8S), ASTM A276, ASTM A479, ASTM A580
