317L(1.4438) General Property
Alloy 317LMN uye 317L molybdenum-inotakura austenitic simbi isina tsvina chubhu ine yakawedzera kupikisa kurwisa kemikari kana ichienzaniswa neyakajairika chromium-nickel austenitic simbi isina tsvina pombi yakadai seAlloy 304. Pamusoro pezvo, 317LMN uye 317L alloys, kushushikana-kune zvinokambaira zvakanyanya. -kutsemuka, uye kusimba kusimba patembiricha dzakakwirira pane dzakajairwa simbi dzisina tsvina. Ese akaderera kabhoni kana "L" mamakisi kuti ape kupokana kwekunzwa panguva yewelding uye mamwe maitiro ekupisa.
Mazita ekuti "M" uye "N" anoratidza kuti zvinyorwa zvine huwandu hwemolybdenum nenitrogen zvakateerana. Iko kusanganiswa kwe molybdenum ne nitrogen kunonyanya kushanda mukusimudzira kuramba kugomba uye kukoromoka, kunyanya muhova dzine acids, chlorides, uye sulfur compounds patembiricha yakakwira. Nitrogen inoshandawo kuwedzera simba reaya alloys. Ose maalloys anoitirwa akanyanya sevhisi mamiriro senge flue gas desulfurization (FGD) masisitimu.
Kuwedzera kune yakanakisa corrosion kuramba uye simba zvivakwa, iyo Alloys 316, 316L, uye 317L Cr-Ni-Mo alloys zvakare inopa yakanakisa yekugadzira uye kuumbwa kwakafanana neiyo austenitic stainless simbi tubing.
317L (1.4438) Kurapa KupisaAnnealing
Iyo austenitic Stainless simbi pombi inopihwa muguyo annealed mamiriro akagadzirira kushandiswa. Kurapa kwekupisa kungave kuri madikanwa panguva kana mushure mekugadzira kuti ubvise mhedzisiro yekutonhora kuumba kana kunyungudutsa yakawedzera chromium carbides inokonzerwa nekufumurwa kwekupisa. Kune maAlloys 316 uye 317L mhinduro anneal inoitwa nekudziisa mu1900 kusvika 2150 ° F (1040 kusvika 1175 ° C) tembiricha inoteverwa nekutonhodzwa kwemhepo kana kudzima kwemvura, zvichienderana nekukora kwechikamu. Kutonhodza kunofanirwa kukurumidza kukurumidza kuburikidza ne1500 kusvika 800 ° F (816 kusvika 427°C) kudzivirira kudzokororwa kwechromium carbides uye kupa optimum corrosion resistance. Muchiitiko chese, simbi inofanira kutonhodzwa kubva kune annealing tembiricha kusvika kune yakasviba kupisa mukati memaminitsi asingasviki matatu.
Forging
Iyo inokurudzirwa yekutanga tembiricha yemhando ndeye 2100-2200 ° F (1150-1205 ° C) ine kupedzisa kwe1700-1750 ° F (927-955 ° C).
Annealing
317LMN uye Alloy 317L simbi isina tsvina inogona kuvharwa mutembiricha ye1975-2150 ° F (1080-1175 ° C) inoteverwa nemhepo inotonhorera kana kudzima mvura, zvichienderana nekukora. Ndiro dzinofanirwa kuvharwa pakati pe2100°F (1150°C) ne2150°F (1175°C). Iyo simbi inofanira kunyoroveswa kubva kune annealing tembiricha (kubva tsvuku / chena kusvika dema) musingasviki maminetsi matatu.
Kuoma
- Aya magiredhi haana kuomeswa nekurapa kupisa.
- Alloys 316 uye 317L Stainless simbi chubhu haigone kuomeswa nekupisa kurapwa.
FAQQ: Uri kutengesa kambani kana mugadziri?
A: Isu tiri kambani yekutengesa ine makore anopfuura gumi neshanu ruzivo mubhizinesi rekutengesa kunze simbi, tine kushandira pamwe kwenguva refu nezvigayo zvikuru muChina.
Q:Uchaendesa zvinhu nenguva here?
A: Hongu, tinovimbisa kupa zvigadzirwa zvemhando yepamusoro uye kuendesa panguva.Kutendeseka ndiyo tsika yekambani yedu.
Mubvunzo:Unopa samples here? ndezvemahara here kana kuwedzera?
A: Sample inogona kupa mutengi mahara, asi mutakuri wekutakura achavharwa neakaundi yevatengi.
Mubvunzo: Unobvuma kuongororwa kwechitatu here?
A: Hongu tinobvuma zvachose.
Mubvunzo: Ndezvipi zvigadzirwa zvako zvikuru?
A: Carbon simbi, alloy simbi, Stainless simbi ndiro/coil, pombi uye fittings, zvikamu etc.
Q: Unogona kugamuchira kurongeka kwecustomer?
A: Hongu, tinovimbisa.
