A2-60, A2-70, A2-80 Austenitic bakin karfe zagaye sanduna da mashaya hexagonal

A1, A2, A4 suna wakiltar 302, 304, 316;45, 50, 60, 70, 80 suna wakiltar 1/10 na mafi ƙarancin ƙarfin ɗaure.A4 ne austenitic bakin karfe, ɓullo da ga tafasa sulfuric acid, Saboda haka, sunan ne acid-resistant karfe, wanda nasa ne metastable acid-resistant karfe, yawanci a madadin SUS316.
A yana wakiltar "austenite", 2 yana wakiltar abu na biyu (a zahiri, 2 yana nufin 304), kuma -70 yana wakiltar matakin ƙarfin shine 700 MPa.Abubuwan gama gari sune A2 da A4, waɗanda sune 304 da 316 bi da bi, amma idan dai injiniyoyi za su iya tabbatar da Aiki, abun da ke tattare da sinadarai zai iya shigowa da fita.Maki gama gari sune:

A1, A2, A4 suna wakiltar 302, 304, 316;45, 50, 60, 70, 80 suna wakiltar 1/10 na ƙaramin ƙarfi na maɗauri.
A4 bakin karfe ne austenitic wanda aka ƙera don tafasa sulfuric acid.Sabili da haka, ana kiran ƙarfe mai jure acid a matsayin ƙarfe mai jurewa acid, yawanci SUS316.70 da 80 da ke bayan A4-70 da A4-80 suna wakiltar 1/10 na ƙaramin ƙarfi na maɗauri.A4-70 da A4-80 ba su bambanta da kayan kanta ba.Tunda suaustenitic bakin karfe mashaya, ba za a iya bi da su ta hanyar maganin zafi ba.Hanya don inganta ƙarfin juzu'i, haɓaka ƙarfin ƙarfi shine ta hanyar nakasar shingen ɓarna (wanda aka fi sani da hardening sanyi), ƙusoshin A4-70 akan kasuwa fiye da wurare dabam dabam, A4-80 rare.
