Stainless Simbi 304 1.4301

Stainless simbi 304 uye Stainless simbi 304L inozivikanwawo se 1.4301 uye 1.4307 zvakateerana. Type 304 ndiyo inonyanya kushandiswa uye inoshandiswa zvakanyanya simbi isina tsvina. Ichiri dzimwe nguva inodaidzwa nezita rayo rekare rekuti 18/8 iro rinotorwa kubva mukuumbwa kwezita 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 gauge 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.

Alloy Designations

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

Corrosion Resistance

304 ine yakanakisa corrosion kuramba munzvimbo dzaMay uye kana ichisangana neyakasiyana corrosion media. Gomba uye kukoromoka kunogona kuitika munzvimbo dzine chlorides. Stress corrosion cracking inogona kuitika pamusoro pe60°C.

Heat Resistance

304 ine kumira kwakanaka kune oxidation musevhisi yepakati kusvika ku870 ° C uye mukuenderera sevhisi kusvika 925 ° 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.

Fabrication

Kugadzirwa kwesimbi isina 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.

Kutonhora Kushanda

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

Hot Working

Nzira dzekugadzira dzakaita sekugadzira, dzinosanganisira kushanda kunopisa dzinofanirwa kuitika mushure mekudziya kweyunifomu kusvika 1149-1260 ° C. Izvo zvinogadzirwa zvinofanirwa kukurumidza kutonhodzwa kuti ive nechokwadi chekusagadzikana kwakanyanya.

Machinability

304 ine yakanaka machinability. 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.

Kupisa Kurapa

304 simbi isina tsvina haigoni kuomeswa nekurapa kwekupisa. Kugadziriswa kwekugadzirisa kana kuvhara kunogona kuitwa nekukurumidza kutonhora mushure mekudziya kusvika 1010- 1120 ° C.

Weldability

Fusion welding performance yemhando 304 simbi isina tsvina yakanakisa zvese zvine uye pasina mafirita. Yakakurudzirwa mafirita tsvimbo uye maelectrode esimbi isina simbi 304 igiredhi 308 simbi isina tsvina. Kune 304L iyo yakakurudzirwa yekuzadza ndeye 308L. Heavy welded zvikamu zvingada post-weld annealing. Iyi nhanho haidiwe kune 304L. Giredhi 321 inogona kushandiswa kana post-weld kupisa kurapwa kusingaite.
