Nyora 321 (UNS S32100) muCoil tubing
Tsanangudzo
Type 321 ititanium yakagadzikana chromium nickel austenitic Stainless simbi ine corrosion resistance yakafanana ne304/304L.Iri giredhi rinowanzo shandiswa mu 800-1500˚F tembiricha renji parinodzikamiswa kurwisa kunaya kwechromium carbide nekuwedzera kwetitanium, izvo zvinokonzeresa kunaya kwetitanium carbides.Type 321 ine yakanakisa intergranular corrosion resistance mushure mekuratidzwa kune iyi tembiricha renji, uye giredhi iri rinoramba oxidation kusvika 1500˚F uye ine yakakwira creep uye kusagadzikana kuputika zvivakwa kupfuura 304/304L.Iyo zvakare ine yakanaka yakaderera tembiricha kuoma uye isiri-magnetic mune annealed mamiriro.
321 simbi isina tsvina yakakoswa tubing
