He aha ka A2-70?
He aha ka A2-70 i hana ʻia he nīnau maʻamau i ka ʻoihana kemika a me nā mea paʻa. He mea koʻikoʻi ka hoʻomaopopo ʻana i nā mea waiwai, nā waiwai a me nā noi o A2-70 e hōʻoia i ka holomua o kāu papahana. Ma kēia ʻatikala, e hāʻawi mākou i kahi kikoʻī kikoʻī o ka wehewehe ʻana i nā mea waiwai, haku mele, a me nā waiwai o A2-70 a me kāna mau noi i nā ʻano ʻoihana like ʻole.
Wehewehe kumu o ka mea A2-70
ʻO A2-70 e pili ana i kahi kikoʻī o ka austenitic stainless steel i hoʻohana mau ʻia i nā mea paʻa e like me nā bolts, nuts a me nā screws. ʻO A2 ke ʻano o ke ʻano mea, ʻoiai ʻo 70 e hōʻike ana i kona helu ikaika tensile. ʻO ka mea kikoʻī, ua kūlike ka mea A2-70 i ka ISO 3506 maʻamau no nā māka kila kila, a loaʻa iā ia nā waiwai maikaʻi loa e pili ana i ka pale ʻana i ka corrosion a me ka ikaika mechanical.
ʻO ka hui kemika o A2-70
Hāʻule nā ​​mea A2-70 ma lalo o ka māhele o 304 stainless steel, me nā mea nui me ka hao, chromium (18%), nickel (8%), a me kahi liʻiliʻi o ke kalapona (maximum 0.08%). Hāʻawi ka hui kemika o kēia huila i ke kūpaʻa maikaʻi a me ka ikaika mechanical. ʻO ka mea kūikawā, ʻo ka hoʻohui ʻana o ka chromium e hana i kahi kiʻiʻoniʻoni pale o ka chromium oxide, kahi e pale pono ai i ka oxidation a me ka corrosion. ʻO ka mea nickel, ma ka ʻaoʻao ʻē aʻe, hoʻonui i ka ductility a me ka paʻakikī o ka mea, e hoʻonui hou i kona hiki ke hoʻohana ʻia i nā wahi paʻakikī.
Nā Pono Mechanical o A2-70
ʻO nā waiwai mīkini kahi kumu nui i ka hoʻomaopopo ʻana i ka mea i hana ʻia ai ka A2-70, ʻoiai ʻo A2-70 ka ikaika tensile o 700 MPa ma lalo o 700 MPa, kahi i loaʻa mai ai ka "70". Eia kekahi, ʻo A2-70 he pale ʻili maikaʻi, ductility a me ka ikaika luhi. kaumaha.
Nā wahi noi no nā mea A2-70
Ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion a me nā waiwai mechanical, hoʻohana ʻia nā mea A2-70 i nā ʻano ʻoihana ākea, ʻoi aku hoʻi i nā ʻāpana kemika, moana, kūkulu hale a me nā meaʻai. I ka ʻoihana kemika, hoʻohana maʻamau ʻia ʻo A2-70 i nā lako a me nā ʻōnaehana paipu e pono ai ke kūʻē i nā kemika corrosive. ʻO ke kūpaʻa ʻana o ka corrosion o A2-70 he mea koʻikoʻi nō hoʻi i nā kaiapuni moana, kūpono ia no ka hoʻohana ʻana i ka hana moku, nā ʻaila ʻaila ma waho, a me nā noi ʻē aʻe e pono ai ke kūʻē i ka ʻino o ke kai.
ʻO nā pono a me nā pōʻino o ka A2-70 mea nānā
Ke hoʻohālikelikeʻia me nā mea kila kila'ē aʻe, he nui nā mea maikaʻi o A2-70, e like me ke kū'ēʻana i ka corrosion maikaʻi, ka ikaika mechanical kiʻekiʻe a me ka nui o nā noi. Loaʻa iā ia kekahi mau palena. ʻAʻole kūpono ʻo A2-70 no ka hoʻohana ʻana i nā kaiapuni me kahi kiʻekiʻe o nā ion chloride, no ka mea hiki ke alakaʻi i ka ʻinoʻino. ʻAʻole kūpono ia no ka hoʻohana ʻana i nā wahi wela kiʻekiʻe loa.
Hōʻuluʻulu manaʻo
ʻO ka pane i ka nīnau o ka mea i hana ʻia ʻo A2-70, ʻo ia ka A2-70 he austenitic stainless steel mea i hoʻokumu ʻia ma 304 stainless steel, nona ke kūpaʻa corrosion maikaʻi a me ka ikaika mechanical, a hoʻohana nui ʻia i nā kula he nui e like me ka ʻoihana kemika, moana, a me ke kūkulu ʻana. ʻO ka hoʻomaopopo ʻana i nā waiwai waiwai a me nā hiʻohiʻona noiʻi o A2-70 e kōkua i ka hana ʻana i kahi koho mea i ʻike ʻia i nā papahana ʻenekinia.
Ma o ka hoʻomaka ʻana o kēia ʻatikala, manaʻo wau ua loaʻa iā ʻoe kahi ʻike hohonu loa o nā mea A2-70, e hāʻawi ana i ka ʻike waiwai no nā hoʻoholo papahana e hiki mai ana.
