A2-60, A2-70, A2-80 Austenitic stainless hlau puag ncig tuav thiab hexagonal bar
A1, A2, A4 sawv cev 302, 304, 316; 45, 50, 60, 70, 80 sawv cev rau 1/10 ntawm qhov tsawg kawg nkaus tensile lub zog ntawm fasteners. A4 yog austenitic stainless hlau, tsim rau boiling sulfuric acid, Yog li ntawd, lub npe yog acid-resistant steel, uas belongs rau metastable acid-resistant steel, feem ntau yog sawv cev ntawm SUS316.
A sawv cev rau "austenite", 2 sawv cev rau cov khoom siv thib ob (qhov tseeb, 2 yog hais txog 304), thiab -70 sawv cev rau qib zog yog 700 MPa. Cov khoom siv feem ntau yog A2 thiab A4, uas yog 304 thiab 316 raws, tab sis ntev li ntev tau cov tshuab tuaj yeem lav qhov kev ua tau zoo, cov tshuaj muaj pes tsawg leeg tuaj yeem nkag mus thiab tawm. Cov qhab-nees feem ntau yog:
A2-60
A2-70
A2-80
A4-70
A4-80
A4-90
A1, A2, A4 sawv cev 302, 304, 316; 45, 50, 60, 70, 80 sawv cev rau 1/10 ntawm qhov tsawg kawg nkaus tensile lub zog ntawm fastener.
A4 yog ib qho austenitic stainless hlau uas tau tsim los rau boiling sulfuric acid. Yog li ntawd, cov kua qaub-resistant steel yog lub npe hu ua metastable acid-resistant steel, feem ntau SUS316. Lub 70 thiab 80 tom qab A4-70 thiab A4-80 sawv cev rau 1/10 ntawm qhov tsawg kawg nkaus tensile lub zog ntawm fastener. A4-70 thiab A4-80 tsis txawv ntawm cov khoom nws tus kheej. Txij li lawv yogaustenitic stainless hlau bar, lawv tsis tuaj yeem kho los ntawm kev kho cua sov. Cov txhais tau tias los txhim kho lub zog tensile, qhov nce ntawm tensile lub zog yog los ntawm kev deformation ntawm lub dislocation barrier (feem ntau hu ua txias hardening), A4-70 bolts nyob rau hauv kev ua lag luam tshaj cov kev ncig, A4-80 tsawg.
