DESCRIPTION
Simbi isina simbi 317L igiredhi remolybdenum rine yakaderera kabhoni, pamwe nekuwedzera kwechromium, nickel, uye molybdenum. Izvi zvinopa zviri nani kusadzivirirwa nekuora uye kuwedzera kuramba kurwiswa kwemakemikari kubva kuacetic, tartaric, formic, citric, uye sulfuric acid. 317L machubhu / mapaipi anopa kukwira kwepamusoro, uye kuramba kwekunzwa kana yakasungwa, nekuda kwekuderera kwekabhoni. Kuwedzera mabhenefiti anosanganisira kushushikana kuputsa kuramba, uye kusimba kusimba patembiricha yakakwira. Giredhi 317l mapaipi esimbi haasi-magnetic mune annealed mamiriro. Nekudaro, post-welding diki magineti inogona kucherechedzwa.
317L STAINLESS SIMBA PAMBI ZVINHU
317L Stainless simbi machubhu anopihwa neArch City Steel & Alloy ane zvinotevera zvivakwa:
Corrosion Resistance:
- Inoratidza kusadzivirirwa nekuora munzvimbo dzakasiyana siyana, kunyanya munzvimbo dzine acidic chloride uye huwandu hwakawanda hwemakemikari.
- Yakanakisa corrosion kuramba mumashandisirwo uko kushomeka kusvibiswa kunodiwa
- 317L simbi isina tsvina chubhu / pombi ine yakaderera kabhoni yemukati inopa kumira kwakanaka kune intergranular corrosion.
- Tsika yesimbi yekugomba kana ikasangana nechlorides, bromides, phosphorus acids, uye iodides inodzvinyirirwa.
Heat Resistance:
- Yakanakisa kuramba kune oxidation nekuda kwechromium-nickel-molybdenum yemukati.
- Inoratidza mwero wakaderera wekuyera patembiricha inosvika 1600-1650 ° F (871-899 ° C), mumhepo yakajairika.
Welding Hunhu:
- Kunze kweiyo oxyacetylene welding, yakabudirira yakakwenenzverwa neese zvakajairika fusion uye nzira dzekupikisa.
- Filler simbi ine nickel-base uye yakakwana chromium uye molybdenum zvirimo zvinofanirwa kushandiswa kubatanidza Type 317L simbi. Izvi zvinobatsira mukusimudzira corrosion resistance yewelded product. AWS E317L/ER317L kana austenitic, yakaderera kabhoni yekuzadza simbi ine yakakwira molybdenum yemukati kupfuura giredhi 317L inogona zvakare kushandiswa.
Machinability:
- Kushanda paLow kumhanya neanogara achidya kunobatsira kudzikisira maitiro egiredhi 317L mapaipi ekuomesa.
- Giredhi 317L pombi dzesimbi dzakasimba kupfuura 304 dzisina tsvina uye dziri pasi pehurefu uye tambo chip kana ichigadzirwa. Saka, kushandiswa kwema chip breakers kunokurudzirwa.
Applications:
Grade 317L Stainless simbi machubhu anowanzo shandiswa kubata doro, acid dhayi, bleaching mhinduro, acetylating uye nitrating musanganiswa, etc. Mamwe chaiwo mashandisirwo egiredhi 317L machubhu nemapombi anosanganisira:
- Kemikari uye petrochemical processing equipment
- Mapepa uye pulp kubata michina
- Zvigadzirwa zvekugadzira chikafu
- Condensers muzviteshi zvenyukireya uye fossil powered
- Textile midziyo
