Type 347 (UNS S34700) muCoiled tubing
Tsanangudzo
347 simbi isina tsvina yakakoswa tubing
Type 347 is niobium stabilized chromium nickel austenitic stainless steel ine corrosion resistance yakafanana ne304/304L.Iri giredhi rinowanzo shandiswa mu 800-1500˚F tembiricha renji parinodzikamiswa kurwisa kunaya kwechromium carbide nekuwedzera niobium, izvo zvinokonzeresa kunaya kweniobium carbides.Type 347 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.
