QN1803 (304D) Stainless simbi ndiro
1. Tsanangudzo:
Chigadzirwa chitsva chegiredhi QN1803 ndiyo yekutanga pasirese yakakwira, yakakwira corrosion resistance, nickel-saving austenitic stainless steel product.
Pahwaro hwekuona kuti corrosion kuramba yakaenzana ne304 simbi isina tsvina, kusimba kwechinhu chacho kunovandudzwa, uye zvinhu.
mutengo unoderedzwa, uchiita kuti uwedzere kudhura uye kukwikwidza pamusika pane 304 simbi isina tsvina.
Zvitsva zvekugadzirwa kwezvigadzirwa zvekugadzira zvinhu: high nitrogen (≥2000ppm), high chromium (≥18%), nickel yepakati (~ 3.0%) uye mhangura yakakwirira (≥1.5%).
Kuburikidza nedhijitari R&D chikuva Thermo-Calc thermodynamic phase diagram kuverenga software uye yekuyedza data data, kugadzirisa iyo
alloying zvinhu zvechikamu chega chega hachingonatsiridze kushora kwechigadzirwa, asiwo chinoita kuti goho resimba reQN1803 riwedzere.
kupfuura 1.3 nguva iyo ye304.
QN1803 ine zvinotevera maficha:
1) iyo pitting corrosion yakaenzana PREN=Cr+3.3Mo+30N-Mn iri pamusoro pe 19.0, iyo inenge yakafanana negomba corrosion resistance se 304.
simbi isina ngura.
2) iyo yunifomu yekudzivirira ngura mu dilute hydrochloric acid, dilute sulfuric acid, acetic acid + munyu uye mamwe nharaunda zviri nani kupfuura.
304 simbi isina tsvina.
3) iyo corrosion kuramba iri nani pane 304 munzvimbo chaiyo yekushandisa mushure mekukotama, kutsika, kuoma uye kumwe kutonhora kuumba.
4) simba regoho rinopfuura 1.3 nguva ye304 simbi isina tsvina, uye ine elongation isiri pasi pe45%. Pfeka kuramba uye
kuneta kuita kuri nani pane 304 simbi isina tsvina.
5) kushanda kwakanaka kwewelding, simba mushure mekukwidibira rakakwirira kudarika 304 simbi isina tsvina, uye kupikisa kwekuora ndiko.
kuenzaniswa ne304 simbi isina simbi.

7.Kushandisa:
➢ Indasitiri yekuvaka: matenga ekuvaka, madziro, purlins, inotakura mitoro yezvimiro, nezvimwe.
➢Magonhi emidziyo nemahwindo: semigero yepasi, mahinji, mahinji, masiraidhi, nezvimwewo;
➢Mapombi akashongedzwa anoshongedzerwa: sefenzi, zvinovharira chiteshi, masitepisi, mahwindo edziviriro nezvimwe;
➢Mapombi akakandwa mumaindasitiri: sepombi dzegasi, pombi dzesuweji dzemaindasitiri;
➢Magaba ematangi emaindasitiri: semagasi emvura, shongwe dzekubvisa gasi;
➢ Midziyo yekuberekesa: yakaita sedhiri rekudyisa nguruve, dhishi remachira maviri;
➢ Zvivakwa zvemakanzuru: zvakaita sedzimba dzemabhazi, nzvimbo dzekugezesa tsvina.
