440 simbi - Stainless simbi. Steel 440: unhu

Steel akadana remubatanidzwa nesimbi uye kabhoni. Types emashoko havasi kutsunga kuburikidza nhamba inokosha zvinoriumba, uye maererano netsvina uye yokuvirisa vabvunza chigadzirwa zvivako siyana uye unhu.

Mhando simbi, maererano Pricing mutemo inogona rakakamurwa subgroups, cheap, dzakakurumbira uye zvinodhura. Zvose zvinoenderana nechinangwa zvokunyama matambudziko ayo kugadzirwa. Uyezve, hapana chakanaka kana chakaipa inonanga chiwanikwa, sezvo kushingaira acho unotora chisinganzwisisiki hwounhu kuti kuita. Zvakananga, unogona kuonekwa kana isu funga Somuenzaniso, 440 simbi.

simbi zvinoriumba

Quality simbi chinofanira kuzivikanwa panguva vanopfeka nemishonga, kusimba, elasticity, ductility, kusimba, kutsungirira uye ngura kugona Sharpening. In tsika, vanenge vose zvivako izvi zvinopesana chimwe nechimwe vamwe. Chimwe chikuru pezvokuvamba chiwanikwa, ndiye kwekuoma uye Rigidity, ndiye kabhoni. Nokuti yeimwe dzakakwirira zviri mairi zvinosanganisira vaya iyo wevasungwa munhu akapiwa kwemakemikari Kufananidzira mukuru 0.5%. Pfeka kurwisa pfuma uye pasi propensity kuti ngura anomupa Chrome simbi. Kana pamwero mukuru kupfuura 13%, simbi iyi Stainless zvigadzirwa.

Grain saizi, simba, kuomarara anopa chiwanikwa kuti manganese. It rinoshandiswa danho nokuchengetedza tikaisa. Izvi zvinonzi akauraya simbi.

To chigadzirwa ichi acho akanga asina pfava uye kusimba uye asi husingakwanisi kudziyisa, remubatanidzwa iri awedzera molybdenum. Panyaya iyi, iyo chiwanikwa inonzi mhepo-ukadzimwa.

Zvinobatsira yekuzvidzivirira ngura uye anopa neukukutu nickel. Property Fortress anotipa zvinhu nesilicon. Tungsten uye vanadium chiwanikwa anopa simba uye mukurumari.

Features simbi giredha 440

440 chokuita Stainless simbi zvokuvakisa. Rinoshandiswa zvikurukuru kugadzirwa mapanga, kuvaka zvivako. The runoratidza chiwanikwa izvi husingakwanisi ngura uye yakakwirira simba. Uyewo pane dzino ndiko zvakanaka kuramba zvezvakatipoteredza zvinhu, mvura, kuti zvokudya, simba acids uye alkalis.

Steel mugwaro 440 vanosanganisira subspecies 440A, 440B, 440C, uye 440A dzinoti - mamwe manyoro uye 440C - zvakasimba. Zvisinei, drawback ndiye fragility kuti 440C uye vade nemishonga ngura pachinhu 440A uye 440B. Zvakaratidza kuti ngura anogona musiwa kwenguva refu nevanhu unyoro kana hasha vezvenhau. Kunyange zvazvo mimwe ehupfumi, ngura chokudzivirira, anopa chiwanikwa ichi nokuda kumeso yakabwinyiswa pamusoro.

Hazvina varumbidzwa kushandisa 440 simbi ari tembiricha yakakwirira kupfuura kupisa kwaro panguva parwendo, sezvo iri kana zvemaziso ehupfumi ari chiwanikwa vakarasika.

Makemikari anoumba simbi 440

Steel 440, hunhu izvo zvakananga novimba makemikari anoumba, maererano series, rine mamiriro okunze zviri patafura pazasi.

Sezvinoratidzwa tafura inoratidza yakadereresa kabhoni zviri 440A series, chikuru - 440C, ndiko kuti, ichangobva muchiso akasimba kupfuura zvose, uye vokutanga ndiyo husingakwanisi ngura. Kunyange zvazvo dzakatevedzana dzose zvizivikanwe nokururama yepamusoro uye mutoro chinja zvakanaka.

Mumuviri zvivako uye chafariz vabatwe Stainless simbi 440

Steel 440 mumuviri zvatariswa parameters nokuda akatevedzana A, B uye C ane zvinotevera:

• zvinhu arambe achirema - 7650 makirogiramu / bv. M;
• modulus - 200 GPA;
• chafariz conductivity - 242 W / m kbp;.
• dzakananga kupisa vanokwanisa - 460 J / kg.kb;.
• yemagetsi resistivity - 600.

Kwekuoma simbi 440 kunosiyana-siyana mukati 56-58 dzakabatana.

Paavhareji chafariz kuwedzera coefficient, iyo unotaurwa mm / m / dhigirii chilis pa 440A dzakatevedzana - 10.1; 440B - 10.3; 440C - 11.7.

Kupisa vabatwe ichi zvinhu ichipfuura anotevera:

• annealing;
• richipedza;
• zororo.

Annealing kunoitika panguva imwe tembiricha kuti + 850-900 Celsius, zvichiteverwa kugara rutapudzo kuti _600. Kutonhora kunoitika nendege nzira. Zvadaro - nzira damped annealing pa 735-785 madhigirii uye kutonhora muchoto.

Tempering rinoitwa pa + 1010-1065 Celsius. Richipedza - kushandisa mafuta inodziya kana mhepo.

Vacation rinopfuura pa + 150-370 madhigirii, saka kuti mashoko anopiwa zvakakodzera pokuoma. Pakati akasiyana zvinhu zvakadai simbi 440, hunhu zvokuimba chiito munguva yakanaka 440C inotakura. chiwanikwa ichi ndicho inodhura uye hwakavimbika. It inorondedzera zvigadzirwa yepamusoro mureza.

Mafomu Steel 440

440 Stainless hwendarira kunyanya kushandiswa kugadzirwa mapanga. Haya akapiwa chiwanikwa yokuvaka zvigadzirwa izvo welded kana zvimwe yeimwe.

Machira ane apera zvigadzirwa anobudiswa ne ukobvu kubvira 4 kusvika 50 mm. 440 simbi hakurevi kuwedzere achawanda nokupisa kurapwa panguva yake nomoto. Nyore uye yakavimbika chiwanikwa nokuda pagadzirwe mabheyaringi, zvidimbu nyere Fittings.

440A of zvizivikanwe unobereka zvakawanda vachinyara mapanga, kusanganisira pasi pemvura, kuvhima. The mashizha ari 440C dzinotevedzana dzine yakanakisa nokuveza zvivako uye nokufumura Sharpening zvakanaka, saka simbi iri rakashandiswa pagadzirwe vepamusoro okurwadzisa Ezvemutauro.

Unofanira kuziva kana kutenga banga akanzi "440" kuti anoshandiswa chiwanikwa kudhura - 440A. Kana anodhura yeimwe 440B uye 440C vagadziri nguva dzose kuriteerera.

nzira muchiso

Pane imwe nhamba kungaitwa pane mavanga, izvo zvinogona kutsiviwa chiwanikwa ichi. Somuenzaniso, dzakatevedzana 440A / B ane zvimwe zvinhu kuti kuvandudza ngura nemishonga. Steel 440F ane yepamusoro workability panguva yakafanana simba. Muduku pachavo maitiro avo kwekuoma giredhi 420. 416 dzakatevedzana ane mukuru workability asi yakaderera rakavimbika.

Kana kuti mapanga kubva 440A muchiso uye ayo analogs, zvigadzirwa izvi yakakodzera kushandiswa nezuva. Kunyange, zvinokosha kufungawo unhu richipedza. Well nekusimba mune izvi yakasimba VaK. The kambani "Randall" kunyanya unobereka simbi mashizha 440B.
