2. 304L insimbi engagqwali. Ukuze kuxazululwe inkinga yokuthuthukiswa kwe-ultra-low carbon austenitic stainless steel ngenxa yemvula ye-Cr23C6 ebangela ukuthambekela okukhulu kokugqwala kwe-intergranular kwensimbi engagqwali engama-304 ngaphansi kwezinye izimo, ukumelana kwayo nokugqwala kwe-intergranular kungcono kakhulu kunokwe-304 stainless. insimbi. Ngaphandle kwamandla aphansi kancane, ezinye izakhiwo ziyafana nensimbi engagqwali engu-321. Isetshenziselwa ikakhulukazi okokusebenza okumelana nokugqwala kanye nezingxenye ezingakwazi ukuphathwa ngesixazululo ngemva kokushisela, futhi ingasetshenziswa ukwenza imizimba yezinsimbi ehlukahlukene.

3. 304H insimbi engagqwali. Igatsha langaphakathi le-304 insimbi engagqwali inengxenye ye-carbon mass engu-0.04% -0.10%, futhi ukusebenza kwayo kwezinga lokushisa eliphezulu kungcono kunaleyo ye-304 yensimbi engagqwali.

4. 316 insimbi engagqwali. Ukwengeza i-molybdenum ngesisekelo sensimbi engu-10Cr18Ni12 kwenza insimbi ibe nokumelana okuhle nokunciphisa ukugqwala okuphakathi nendawo. Emanzini olwandle nakweminye imidiya ehlukahlukene, ukumelana nokugqwala kungcono kunensimbi engagqwali engama-304, esetshenziselwa ikakhulukazi izinto ezingangeni emgodini.

5. 316L insimbi engagqwali. I-Ultra-low carbon steel inokumelana kahle nokugqwala kwe-intergranular okuzwela futhi ifanele ukwenziwa kwezingxenye ezishiselwe kanye nezinto zokusebenza ezinobukhulu bezingxenye eziwugqinsi, njengezinto ezimelana nokugqwala emishinini ye-petrochemical.

6. 316H insimbi engagqwali. Igatsha langaphakathi le-316 insimbi engagqwali inengxenye ye-carbon mass engu-0.04% -0.10%, futhi ukusebenza kwayo kokushisa okuphezulu kungcono kunokwensimbi engagqwali engu-316.
