A2-60, A2-70, A2-80 Austenitic kuhiliʻole kila poepoe kaola a me ka hexagonal.

A2-60, A2-70, A2-80 Austenitic kuhiliʻole kila poepoe kaola a me ka hexagonal.

A1, A2, A4 hōʻike 302, 304, 316; ʻO 45, 50, 60, 70, 80 e hōʻike ana i ka 1/10 o ka ikaika tensile haʻahaʻa o nā mea hoʻopaʻa. A4 he austenitic stainless steel, i hoʻomohala ʻia no ka paila ʻana i ka sulfuric acid, no laila, ʻo ka inoa he kila ʻakika kūpaʻa, nona ka metastable acid-resistant steel, maʻamau ma ka inoa o SUS316.
He "austenite" ka A, 'o 2 ka lua o ka mea (ma ka 'oia'i'o, 'o 2 'o 304), a 'o -70 'o ka pae ikaika he 700 MPa. ʻO nā mea maʻamau ʻo A2 a me A4, ʻo ia ka 304 a me 316 pakahi, akā ʻoiai hiki ke hōʻoia ʻia ka hana ʻana o ka mīkini, hiki ke komo i waho a i waho. ʻO nā māka maʻamau:
A2-60
A2-70

A1, A2, A4 hōʻike 302, 304, 316; ʻO 45, 50, 60, 70, 80 e hōʻike ana i ka 1/10 o ka ikaika tensile haʻahaʻa o ka mea paʻa.
ʻO ka A4 he kila kila austenitic i kūkulu ʻia no ka hoʻolapalapa ʻana i ka waikawa sulfuric. No laila, kapa ʻia ke kila ʻakika e like me ka metastable acid-resistant steel, maʻamau SUS316. ʻO ka 70 a me 80 ma hope o ka A4-70 a me A4-80 e hōʻike ana i ka 1/10 o ka ikaika tensile haʻahaʻa o ka mea hoʻopaʻa. ʻAʻole ʻokoʻa ʻo A4-70 a me A4-80 mai ka mea ponoʻī. ʻOiai lākouaustenitic stainless steel bar, ʻaʻole hiki ke mālama ʻia e ka mālama wela. ʻO ke ala e hoʻomaikaʻi ai i ka ikaika tensile, ʻo ka hoʻonui ʻana i ka ikaika tensile ma o ka deformation o ka dislocation dislocation (i ʻike pinepine ʻia ʻo ke anuanu paʻakikī), A4-70 bolts ma ka mākeke ma mua o ka circulation, A4-80 rare.
