Andika 321 (UNS S32100) muri Coil tubing
Ibisobanuro
Ubwoko 321 ni titanium itunganijwe ya chromium nikel austenitis ibyuma bitagira umuyonga hamwe no kurwanya ruswa isa na 304 / 304L.Uru rutonde rusanzwe rukoreshwa mubipimo by'ubushyuhe bwa 800-1500˚F aho bihagaze neza kurwanya imvura ya chromium karbide hiyongereyeho titanium, bikaviramo kugwa kwa karubide ya titanium.Ubwoko bwa 321 bufite uburyo bwiza bwo kurwanya ruswa nyuma yo guhura nubushyuhe, kandi iki cyiciro kirwanya okiside igera kuri 1500˚F kandi gifite imiterere nini yo guturika no guhangayika kurenza 304 / 304L.Ifite kandi ubushyuhe buke bwo hasi kandi ntabwo ari magnetique muburyo bwa annealed.
