Kwedo matut pa gin ma ki lwongo ni Stainless Steel ma gengo buru ne i kabedo apar wiye abicel

Ker pa nyonyo ma pe mako nyal me gengo balo pa yamo ki doro ki rwom me chloride ma tye i yamo- pi meno bedo cok ki nam onyo kama chloride-pollution mukene pire tek tutwal.

Kabedo ma tye ki pii maleng-ma calo kulu, nam, pii ma mol onyo pii-gi balo jami ma ki yubu ki cuma malube ki pH, yamo ma ki lwongo ni dissolved oxygen, ki kit ma gi dongo kwede.

Pii ma tye ki acid (me labolle ma ki kwanyo ki i got onyo coal ki tye ki sulfuric acid ma pe ki culu onyo dissolved iron sulfates) tye ki teko madwong loyo pii maleng.

I kabedo ma pii tye iye kadu, kabedo ma ki lwongo ni localized pitting pol kare time pi turo pa passive film- tutwale ka chlorides tye. Bio-fouling ki jami ma ki keto i nam twero yubu oxygen-concentration cells, ma weko lweny oyot. Ka kitiyo ki nyonyo ma pe mako nyal i kabedo ma pii mol iye madwong (me labolle pump impellers) rwom me balo pa jami ma ki lwongo ni austenitic alloys twero bedo piny tutwal. Yub maber-ma calo gengo ka ma obale ki tic ki dul ma pek ma oromo- bene konyo.

Rweny pa nyonyo ma ki yiko ni cung i kom kit ma ngom tye kwede ma pat pat ki ma tek.

Ferritic ki austenitic stainless steels ma tye ki ~14% me chromium gi gengo nitric acid maber.

Kit rwom nyonyo ma pe mako nyal tye ki tic manok i sulfuric acid. acel i kin rwom maber loyo (0Cr17Ni12Mo2) tye ma opore i rwom me lyeto me ot pi rwom ma piny ~15 % onyo ma malo ~85 %.

Gin ma ki lwongo ni Austenitic stainless steels ki tiyo kwede pol kare ki tiyo maber i kabedo ma tye ki phosphoric-acid, kare mukene i lyeto ma romo ~107 °C ki rwom ma pat pat. Gin ma ki lwongo ni Halide (fluoride onyo chloride) ma nok twero, kadi bed kumeno, balo tic. Ferritic ki martensitic steels nen calo tye piny i tic pa phosphoric acid.

Gin ma ki lwongo ni Stainless steels pe rwate pi tic ki hydrochloric-acid-kadi wa i rwom me lyeto ki rwom ma lapiny-pien gin ma ki lwongo ni passive film ni pe twero gwoko rwom ne i kabedo ma tye ki chloride-rich acidic.

Gin ma ki lwongo ni Austenitic stainless steels pol kare gi gengo buru ma aa ki i boric acid, carbonic acid, chloric acid ki chromic acid i rwom ma pat pat ki rwom me lyeto (labongo 100% chloric acid). Gin ma ki lwongo ni Lower-alloy ferritic/martensitic stainless steels pe tiyo maber i kom chromic acid, kadi bed ni gi twero gengo boric onyo carbonic acid maber.

Austenitic nyonyo ma pe mako nyal nyutu teko maber i kom buru pa acetic acid, kadi wa i rwom me lyeto me ot i kom rwom me rwom ma malo.

I rwom me lyeto ma orumowa, gin mo kiken ma ki lwongo ni austenitic nyonyo ma pe mako nyal twero tic ki formic acid maber. Ento, i tic me formic acid ma lyet, jami ma ki lwongo ni non-molybdenum austenitic steels balo oyot- pi meno molybdenum-bearing grades doko gin ma mite. Kit ma ki lwongo ni Martensitic ki ferritic gi timo marac i kom lyeto ma tye i formic acid.

I rwom me lyeto me ot ki rwom ma romo 50%, jami ma ki yubu ki nyonyo ma pe mako buru pol kare nyutu teko maber i kom oxalic acid corrosion. Ento i rwom me lyeto ma malo ki rwom ma malo (me labolle ~100 %) gi twero nongo peko ma dit i kom rwom weny.

Jami mogo ma ki lwongo ni austenitic (me labolle, 0Cr18Ni9) ki twero tic kwede i gwoko lactic-acid i rwom ma piny (ma romo ~38 °C).

Gin ma ki lwongo ni Stainless steels pol kare gi juku jami ma ki lwongo ni alkalis (ma calo ammonium hydroxide) maber.

Gin ma ki lwongo ni Stainless steels pol kare miiyo teko maber i kom jami ma ki lwongo ni acidic salt solutions—ento ngat acel myero otam i kom adwogi pa hydrolyzed acids ma ki yubu ki i salts ki omyero onen ka chlorides onyo halides mukene tye. I te lyeto ma malo, molybdenum-bearing austenitic grades tiyo maber loyo mukene mapol.
