A2-60, A2-70, A2-80 Austenitic steel stainless imivalo ezingqukuva kunye hexagonal bar

A2-60, A2-70, A2-80 Austenitic steel stainless imivalo ezingqukuva kunye hexagonal bar

I-A1, i-A2, i-A4 imele i-302, i-304, i-316; I-45, i-50, i-60, i-70, i-80 imele i-1 / 10 yamandla amancinci amancinci e-fasteners. I-A4 yintsimbi ye-austenitic, ephuhliselwe ukubilisa i-asidi ye-sulfuric, ngoko ke, igama liyintsimbi enganyangekiyo kwi-asidi, eyentsimbi ye-metastable-resistant-resistant, ngokuqhelekileyo egameni le-SUS316.
I-A imele "i-austenite", i-2 imele izinto zesibini (enyanisweni, i-2 ibhekisela kwi-304), kwaye -70 imele inqanaba lamandla yi-700 MPa. Izinto eziqhelekileyo ziyi-A2 kunye ne-A4, eziyi-304 kunye ne-316 ngokulandelanayo, kodwa nje ukuba i-mechanics inokuqinisekiswa kokuSebenza, ukubunjwa kweekhemikhali kungangena kwaye kuphume. Amanqaku aqhelekileyo ngala:
A2-60
A2-70
A2-80
A4-70
A4-80
A4-90
I-A1, i-A2, i-A4 imele i-302, i-304, i-316; I-45, i-50, i-60, i-70, i-80 imele i-1/10 yamandla amancinci okuqina kwe-fastener.
I-A4 yintsimbi ye-austenitic engatyiwayo eyenzelwe ukubilisa iasidi yesulfuric. Ke ngoko, intsimbi enganyangekiyo kwi-asidi ibizwa ngokuba yintsimbi ekwaziyo ukumelana ne-asidi, ngokuqhelekileyo i-SUS316. I-70 kunye ne-80 emva kwe-A4-70 kunye ne-A4-80 imele i-1/10 yamandla amancinci amancinci e-fastener. I-A4-70 kunye ne-A4-80 ayifani nezinto ngokwayo. Ekubeni benjaloiintsimbi ze austenitic stainless bar, abanakunyangwa ngonyango lokushisa. Iindlela zokuphucula amandla okuqina, ukwanda kwamandla okuqina kukuguquguquka kwesithintelo sokususa (esaziwa ngokuqhelekileyo njengokuqina okubandayo), iibholiti ze-A4-70 kwimarike kunokusasazwa, i-A4-80 inqabile.
