Duplex Stainless Simbi

Duplex Stainless steel giredhi 2205 (inozivikanwawo seUNS S31803/S32205, ASTM A240 Rudzi 2205, Inox 2205, AISI 318LN, SUS 329J3L, kana EN 1.4462) iri maviri-chikamu (ferritic 2% alloayteni)-2-2-alloayteni chromium, 2.5–3.5% molybdenum, 4.5–6.5% nickel, uye inenge 0.15% nitrogen. Yayo yakaenzana microstructure inopa yakasarudzika musanganiswa wesimba repamusoro uye yakanakisa corrosion kuramba. Semuyenzaniso, giredhi 2205 rinowanzova nekaviri simba regoho re316L simbi isina tsvina, zvichiita kuti vagadziri vashandise zvikamu zvakatetepa, zvakapfava pasina kupira kuita.

Iyo alloy inowanzo kupihwa mune mhinduro-yakagadziriswa mamiriro (paASTM A240/A240M) kuchengetedza yakanakira duplex chimiro. Giredhi 2205 rinoramba rakaoma kubva kune cryogenic tembiricha (yakatenderedza -50 ° C) kusvika kunosvika +300 ° C; mhiri kweiyi nhanho, brittle sigma chikamu chinogona kuumba mune welds. Izvi zvivakwa zvinoita duplex 2205 sarudzo yakanaka kwazvo yekuda maapplication akadai semakemikari kugadzirisa, offshore oiri & gasi, uye nharaunda dzemugungwa uko zvese zviri zviviri simba repamusoro uye chloride corrosion resistance inodiwa.
