321H Stenles Sil
321H em i wanpela hai-} kabon, titanium-}… i kamap olsem marasin bilong helpim ol samting (UNS S32109), ol i bin wokim bilong mekim wok bilong tempereja i go antap. Komposesen bilong em i gat 17.0-19.0% Cr, 9.0-12.0% Ni, minimam 0.15% Ti, wantaim kabon i kontrolim long 0.04-0.10% —i antap moa long standet 321.
Dispela kabon i go antap i save strongim bikpela strong bilong kripim na resistens bilong bruk, em i bikpela samting long wok yet long 650-900 digri. Titanium i save strongim bel bilong em long daunim wara bilong ka, na rausim korosen namel long ol hangranular long ol hap i gat weldim/hat.
