Stainless Simbi 304L Strip ye wWelding Chigadzirwa uye Equipment

● SAE 304 simbi isina tsvina ndiyo inonyanya kushandiswa. Simbi ine zvese chromium (pakati pe18% ne20%) uye nickel (pakati pe8% ne10.5%), masimbi seakanyanya asiri-iron zvinoriumba. Icho chinonzi austenitic simbi isina tsvina. Iyo ishoma magetsi uye thermally conductive pane kabhoni simbi. Iine magineti, asi ishoma magineti pane simbi. Iyo ine yakakwira corrosion resistance pane simbi yenguva dzose uye inoshandiswa zvakanyanya nekuda kwekureruka kwainoumbwa kuita maumbirwo akasiyana.
The composition was developed by W. H. Hatfield at Firth-Vickers in 1924 and was marketed under the trade name "Staybrite 18/8".
It is specified by SAE International as part of its SAE steel grades. Outside the US it is commonly known as A2 stainless steel, in accordance with ISO 3506 for fasteners.[3] In the commercial cookware industry it is known as 18/8 stainless steel. In the unified numbering system it is UNS S30400 The Japanese equivalent grade of this material is SUS304. It is also specified in European norm 1.4301.

Stainless Simbi 304 1.4301
● Stainless simbi 304 uye simbi isina tsvina 304L inonziwo 1.4301 uye 1.4307 maererano. Type 304 ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya simbi isina tsvina. Ichiri dzimwe nguva inodaidzwa nezita rayo rekare rekuti 18/8 iro rinotorwa kubva muchimiro chezita remhando ye304 ichive 18% chromium uye 8% nickel. Type 304 Stainless steel igiredhi reaustenitic rinogona kudhonzwa zvakadzika. Ichi chivakwa chakonzera kuti 304 kuve giredhi rinonyanya kushandiswa mumashandisirwo senge sink uye saucepan. Type 304L ndiyo yakaderera kabhoni vhezheni ye304. Inoshandiswa mune inorema geji zvikamu zvekuvandudza weldability. Zvimwe zvigadzirwa zvakaita semahwendefa nemapombi zvinogona kuwanikwa se "dual certified" zvinhu zvinosangana nemaitiro eese 304 ne304L. 304H, yakakwira kabhoni yemukati musiyano, inowanikwawo kuti ishandiswe pakupisa kwakanyanya. Zvivakwa zvakapihwa mune ino dhata sheet zvakajairwa kune flat-yakakungurutswa zvigadzirwa zvakafukidzwa neASTM A240/A240M. Zvine musoro kutarisira kuti zvakatemwa mune aya zviyero zvakafanana asi zvisingaite zvakafanana kune zvakapihwa mune ino data sheet.

1.1.1Kushandisa
● Zvirongo
● Zvitubu, screws, nzungu & mabhaudhi
● Sink & splash musana
● Architectural panelling
● Tubing
● Kubika doro, chikafu, mukaka uye zvigadzirwa zvekugadzira mishonga
● Zvigero uye zvimwiro

1.1.2Mafomu Anopihwa
● Shepa
● Kubvisa
● Bhawa
● Ndiro
● Pipe
● Tube
● Koiri
● Fittings

1.1.3 Alloy Mazita
● Stainless simbi giredhi 1.4301/304 inoenderanawo ne: S30400, 304S15, 304S16, 304S31 uye EN58E.

1.1.4Corrosion Resistance
● 304 ine yakanakisa corrosion resistance muMay nharaunda uye kana ikasangana neyakasiyana corrosion media. Gomba uye kukoromoka kunogona kuitika munzvimbo dzine chlorides. Stress corrosion cracking inogona kuitika pamusoro pe60°C.

1.1.5Kuramba Kupisa
● 304 ine kumira kwakanaka kune oxidation mubasa repakati kusvika ku870 ° C uye mubasa rinoramba richienda ku925 ° C. Zvisinei, kushandiswa kushandiswa pa425-860 ° C hakukurudzirwi. Muchiitiko ichi 304L inokurudzirwa nekuda kwekupokana kwayo nekunaya kwecarbide. Panodiwa simba repamusoro patembiricha inopfuura 500°C uye kusvika pa800°C giredhi 304H inokurudzirwa. Nyaya iyi ichachengetedza aqueous corrosion resistance.

1.1.6Kugadzirwa
● Kugadzirwa kwesimbi dzose dzisina tsvina kunofanira kuitwa chete nemidziyo yakatsaurirwa kune simbi isina tsvina. Zvishandiso uye nzvimbo dzebasa dzinofanirwa kunyatsocheneswa usati washandiswa. Aya matanho anodiwa kudzivirira kusvibiswa kwesimbi isina tsvina nesimbi dziri nyore kuita ngura dzinogona kuburitsa ruvara pamusoro pechigadzirwa chakagadzirwa.

1.1.7Kutonhora Kushanda
● 304 simbi isina tsvina inoshanda nyore nyore. Nzira dzekugadzira dzinosanganisira kushanda kunotonhora dzingada nhanho yepakati yekurerutsa kuomesa basa uye kudzivirira kubvarura kana kutsemuka. Pakupedzwa kwekugadzira basa rakazara rekuvhara rinofanira kushandiswa kuderedza kushushikana kwemukati uye kukwidziridza kusaita ngura.

1.1.8Kushanda Kunopisa
● Nzira dzekugadzira dzakaita sekugadzira, dzinosanganisira kushanda kunopisa dzinofanira kuitika mushure mekupisa kweyunifomu kusvika 1149-1260 ° C. Izvo zvinogadzirwa zvinofanirwa kukurumidza kutonhodzwa kuti ive nechokwadi chekusagadzikana kwakanyanya.

1.1.9Machinability
● 304 ine machinability yakanaka. Machining anogona kukwidziridzwa nekushandisa zvinotevera mitemo: Kucheka mipendero kunofanira kuchengetedzwa kwakapinza. Mipendero yakagomara inokonzera kuwandisa basa kuoma. Kuchekwa kunofanirwa kuve kwakareruka asi kwakadzika zvakakwana kudzivirira basa kuoma nekukwira pamusoro pechinhu. Chip breaker dzinofanirwa kushandiswa kubatsira mukuona kuti swarf inoramba iri pachena pabasa. Low thermal conductivity ye austenitic alloys inoguma mukupisa kuisa pamicheto yekucheka. Izvi zvinoreva kuti zvinotonhorera uye mafuta ekuzora anodiwa uye anofanirwa kushandiswa muhuwandu.

1.1.10Kurapa Kupisa
● 304 simbi isina tsvina haigoni kuomeswa nekupisa kupisa. Kugadziriswa kwekugadzirisa kana kuvhara kunogona kuitwa nekukurumidza kutonhora mushure mekudziya kusvika 1010- 1120 ° C.

1.1.11Weldability
● Fusion welding performance for type 304 stainless steel is excellent both with and without fillers. Recommended filler rods and electrodes for stainless steel 304 is grade 308 stainless steel. For 304L the recommended filler is 308L. Heavy welded sections may require post-weld annealing. This step is not required for 304L. Grade 321 may be used if post-weld heat treatment is not possible.
