309 Stainless

UNS S30900 | UNS 30908
Composition (Nominal)
0.20 C (except carbon reduced to 0.08% max. in Type 309S), 2.00 Mn, 0.045 P, 0.030 S, 1.00 Si, 22.00/24.00 Cr, 12.00/15.00 Ni, Bal. Fe

Both are austenitic chromium-nickel alloys and are modifications of Type 304 stainless. They have superior heat-resisting characteristics, slightly better corrosion resistance, and improved creep strength. They have been used for furnace parts, fire box sheets, high-temperature containers, and weld wire.

Specifications: ASME SA479, ASTM A276, ASTM A314, ASTM A479, ASTM A580, QQ-S-763
