QN1803 (304D) Bakin karfe farantin karfe
1. Bayani:
Sabuwar darajar samfurin QN1803 shine babban nitrogen na farko a duniya, babban juriya na lalata, nickel-ceton austenitic bakin karfe samfurin.
Bisa ga tabbatar da juriya na lalata daidai da 304 bakin karfe, ƙarfin kayan yana inganta, da kayan aiki.
an rage farashin, wanda ya sa ya fi tsada kuma ya fi dacewa a kasuwa fiye da 304 bakin karfe.
Sabbin abubuwan ƙirar ƙirar samfur: babban nitrogen (≥2000ppm), babban chromium (≥18%), matsakaicin nickel (~ 3.0%) da jan ƙarfe (≥1.5%).
Ta hanyar dandali na R&D na dijital Thermo-Calc thermodynamic jadawali lissafin software da nazarin bayanan gwaji, daidaitawa.
Alloying abubuwa na kowane lokaci bangaren ba kawai inganta lalata juriya na samfurin, amma kuma ya sa yawan amfanin ƙasa ƙarfi na QN1803
fiye da sau 1.3 na 304.
QN1803 yana da fasali masu zuwa:
1) lalatawar pitting daidai PREN = Cr+3.3Mo+30N-Mn yana sama da 19.0, wanda ke da aƙalla juriyar lalatawar rami iri ɗaya kamar 304
bakin karfe.
2) juriya na lalata iri ɗaya a cikin dilute hydrochloric acid, dilute sulfuric acid, acetic acid + gishiri da sauran mahalli ya fi kyau fiye da
304 bakin karfe.
3) juriya na lalata ya fi 304 a cikin ainihin amfani da jihar bayan lankwasa, stamping, m jihar da sauran sanyi forming.
4) da yawan amfanin ƙasa ƙarfi ne fiye da 1.3 sau na 304 bakin karfe, kuma yana da wani elongation na ba kasa da 45%. Saka juriya da
gajiya aiki ne mafi alhẽri daga 304 bakin karfe.
5) mai kyau waldi yi, da ƙarfi bayan waldi ne mafi girma fiye da na 304 bakin karfe, da kuma lalata juriya ne.
kwatankwacin sa na bakin karfe 304.
