317/317L Stainless simbi kemikari yakagadzirwa

Alloy 317L (UNS S31703) is molybdenum-bearing austenitic stainless steel uye yakawedzera kupikisa kurwisa kwemakemikari kana ichienzaniswa neyakajairwa chromium-nickel austenitic stainless steels seAlloy 304. Pamusoro pezvo, Alloy 317L inopa yakakwira zvinokambaira, kushushikana-kune-kune-kunetseka-kune kuputika, uye kusimba kusimba patembiricha yakakwira kupfuura simbi isina tsvina.Iyo yakaderera kabhoni kana "L" giredhi iyo inopa kuramba kwekunzwa panguva yewelding uye mamwe maitiro ekupisa.

Corrosion Resistance

Iyo yakakwira molybdenum yemukati yeAlloy 317L inovimbisa hukuru hwepamusoro uye hwenzvimbo yekushomeka kwekugara mumidhiya yakawanda kana ichienzaniswa ne304/304L uye 316/316L simbi dzisina tsvina.Mamiriro ezvinhu asingarwise 304/304L simbi isina tsvina kazhinji haizoparadze 317L.Imwe yakasarudzika, zvisinei, yakasimba oxidizing asidhi senge nitric acid.Alloys ane molybdenum kazhinji haaite zvakanaka munzvimbo idzi.

Alloy 317L ine yakanakisa corrosion kuramba kune akasiyana siyana emakemikari.Inopikisa kurwisa mu sulfuric acid, acidic chlorine uye phosphoric acid.Inoshandiswa mukubata inopisa organic uye fatty acids inowanzovapo mune zvekudya uye mishonga yekugadzira mishonga.

Iyo corrosion resistance ye317 uye 317L inofanira kufanana mune chero yakapihwa nharaunda.Iyo imwe chete inosarudzika ndeye iyo alloy ichaiswa kune tembiricha muchromium carbide kunaya kwe800 - 1500 ° F (427 - 816 ° C).Nekuda kweiyo yakaderera kabhoni yemukati, 317L ndiyo inofarirwa zvinhu musevhisi iyi kudzivirira kubva kune intergranular corrosion.

Kazhinji, austenitic Stainless simbi dziri pasi pe chloride stress corrosion cracking in halide service.Kunyange zvazvo 317L ichinyanya kushingirira kustress corrosion cracking pane 304/304L masimbi asina tsvina, nekuda kwehuwandu hwayo hwemolybdenum, ichiri kutapukirwa.

Iyo yakakwirira chromium, 317/317L Stainless simbi kemikari inoumba molybdenum uye nitrogen ye317L inosimudzira kugona kwayo kurwisa gomba uye kukoromoka kwegora pamberi pemakloridi nemamwe halides.Iyo Pitting Resistance Equivalent inosanganisira Nitrogen nhamba (PREN) chiyero chepakati chepitting kuramba.Iyo inotevera chati inopa kuenzanisa Alloy 317L uye mamwe austenitic Stainless simbi.
