Hunan He pai rawa te 316/316L paipa korekore. Me whai korero? Tukuna he imeera ki:sales@hnssd.com
Ko te SS 316,316L, 316H, 316Ti ko nga tohu austenitic 18/8 paerewa molybdenum.
Ko te kowiri tira 316 he kowiri tira chromium-nickel austenitic me te molybdenum. he kowiri tira tuarua he mea nui ki te 304. Ko te molybdenum he 316 pai ake te pai ake o nga ahuatanga parenga waikura katoa atu i te karaehe 304, ina koa he kaha ake te aukati ki te rua me te waikura kapiti i roto i nga taiao hauota.
Kowiri tira Tohu 316 Ko te waro iti austenitic chrome-nickel kowiri tira me te rite te parenga waikura rite momo 316, engari he ātete ki te waikura intergranular muri fehokotaki'anga.
Kowiri tira 316 Ko te karaehe waro teitei ake o te 316, e pai ake ai te maitai mo te whakamahi i nga tono kei te waatea nga wera nui. Ko te Taurite Koeke 316Ti he rite nga ahuatanga. Ko te ihirangi waro kua whakawhānuihia e whakarato ana i te kaha ake me te kaha tuku. Ko te hanganga austenitic o te rauemi ka hoatu i tenei karaehe te tino pakari, tae noa ki te pāmahana cryogenic.
Kowiri tira 316 Tiis Titanium tāpiritanga o 316 maitai. Ko tenei whakaroa ka piki ake te parenga waikura, ka whakapai ake i te parenga poka i roto i nga otinga katote pūhaumāota me te whakakaha ake i te kaha i te pāmahana teitei. Ka pai ake te aukati i te waikura, ina koa ki te sulfuric, hydrochloric, acetic, formic me te tartaric acids, acid sulfates me te alkaline chlorides.
I tua atu, he rereke te hanganga matū me nga ahuatanga o te tinana e whakaatuhia ana i raro nei. Ko enei taonga kua tohua mo nga hua takai papatahi (pepa, pepa me te coil) i ASTM A240 me ASTM A167. paipa me nga ngongo e ai ki te ASTM A213 me te ASTM A149. He rite, engari ehara i te mea he rite nga ahuatanga kua tohua mo etahi atu hua penei i te pae me nga hua hangai i roto i o raatau ake whakaritenga.

I te nuinga, ko te rereketanga nui i waenga i a raatau ko te tono. Ko te 316 te mea taketake ka whakamahia hei whakaiti i te waikawa; Ka whakamahia te 316L hei aukati i te waikura; Ko te 316H te nuinga o te waa e whakamahia ana i roto i te awangawanga teitei o te pāmahana; Ka aukati a 316Ti i te waikura intergranular ma te taapiri titanium.
