Imigoqo eyindilinga yensimbi engagqwali ye-A2-60, A2-70, A2-80 ye-Austenitic kanye nebha enezinhlangothi eziyisithupha

Imigoqo eyindilinga yensimbi engagqwali ye-A2-60, A2-70, A2-80 ye-Austenitic kanye nebha enezinhlangothi eziyisithupha

I-A1, i-A2, i-A4 imele u-302, 304, 316; 45, 50, 60, 70, 80 imele u-1/10 wamandla amancane okunamathela ezintanjeni. I-A4 iyinsimbi engagqwali ye-austenitic, eyenzelwe ukubilisa i-sulfuric acid, Ngakho-ke, igama layo yinsimbi engagqwali, engeyensimbi engagqwali ye-metastable acid, ngokuvamile egameni le-SUS316.
U-A umele “i-austenite”, u-2 umele into yesibili (eqinisweni, u-2 ubhekisela ku-304), kanti u--70 umele izinga lamandla elingu-700 MPa. Izinto ezivamile yi-A2 ne-A4, ezingama-304 kanye no-316 ngokulandelana, kodwa uma nje imishini ingaqinisekiswa Ukusebenza, ukwakheka kwamakhemikhali kungangena futhi kuphume. Amamaki avamile yilawa:
A2-60
A2-70
A2-80
A4-70
A4-80
A4-90
I-A1, i-A2, i-A4 imele u-302, 304, 316; 45, 50, 60, 70, 80 imele u-1/10 wamandla amancane okunamathela kwesibambo.
I-A4 iyinsimbi engagqwali ye-austenitic eyakhelwe ukubilisa i-sulfuric acid. Ngakho-ke, insimbi engagqwali ye-asidi ibizwa ngokuthi insimbi engagqwali ye-asidi, ngokuvamile i-SUS316. Ama-70 nama-80 ngemuva kwe-A4-70 kanye ne-A4-80 amelela ingxenye eyodwa kweziyishumi yamandla amancane okudonsa e-fastener. I-A4-70 kanye ne-A4-80 azihlukile ezintweni ngokwazo. Njengoba zinjaloibha yensimbi engagqwali ye-austenitic, azikwazi ukwelashwa ngokushisa. Izindlela zokuthuthukisa amandla okudonsa, ukwanda kwamandla okudonsa kungokuguqulwa kwesithiyo sokudilika (esaziwa ngokuthi ukuqina okubandayo), amabhawodi e-A4-70 emakethe kunokujikeleza kwegazi, i-A4-80 ayivamile.
