5.4 Corrosion
Although,thepassivelayerisformedonstainlesssteelsurfaces,there are cases when it corrodes due to the following condi‐
ons:
‐Influenceofhydrochloricacidandchlorine,
‐Noongoingmaintenancewhichleadstotheformaonofstrongacidsoluonsonsteelwalls(waterevaporatesandanacid
soluonremains),
‐Anenvironmentmoreaggressivethanthesteelprovidedforit;
‐Contaminaonduringinstallaonandmanufacture(lime,cement,foreignmetallicinclusionsasaresultofusinganglegrind‐
ersnearbyorunsuitableassemblytools),
‐Contactwithnormalcarbonsteel(scratchingwithblacksteelduringtransportaonorstorage),
‐Insufficientroomvenlaonoreventheirabsenceinaggressiveenvironments(theremustalwaysbeanairflowinvenla‐
onducts).
Symptomsofstainlesssteelcorrosionaredifferent.Onecannocethatcorrosionappearsusuallyonvarioustypesofinternal
(non‐metallicinclusions,separaons,deformaons)andexternal(edges,scratches,dents,residuesofscale,sediments,etc.)
surfaces,whilesmoothandhomogenoussurfacesaremuchmoreresistanttocorrosion.Therefore,itisnecessarytoensure
properpicklingandpassivaonofasurface.
Themechanismofdestruconandthetypeofcorrosiondependonaspecificenvironmentandsteelaffectedbyit.Thefol‐
lowingtypesofcorrosionmayoccurdependingontheenvironmentandstainlesssteel:
‐Surface(uniform),Ping,Intergranular,Stress,Crevice.
Pingcorrosionisthemostfrequentlyoccurringcorrosioncausedbyinappropriatestainlesssteelmaintenance,morespecifi‐
callyduetotheuseofchlorinatedcleaningagents.
Pingcorrosionisaformofalocalisedenvironmentalaackleadingtolocallosses(pits)inmaterial.Itiscausedbytheinflu‐
enceofgalvaniccellsformedbetweenapassivatedsteelsurfaceandclearlylocalisednon‐passivaonareaslayingonit.Oxy‐
genoroxidisingsubstancesinacathodiccellareas(passivated)arerequiredforpingcorrosiontooccur.Iftheyareabsent,
cathodicareaspolarizeandthecellstopsfunconing.
Soluonswhichcausepingcorrosionofstainlesssteelsmostfrequentlyarechlorinesoluons.Forthistypeofcorrosion,
condionofasteelsurfaceisveryimportant.Thesmootherandcleanerthesurface,thesmallertheintensityofsaidcorro‐
sion.
Aqualityassessmentoftheeffectsofthistypecorrosionisdifficult,sincedamagecanbeveryseriousataminorweightloss.It
isassumedthatanaveragenumberofpitsperareaunitandtheirgreatestdepthcanserveassomeindicators.

5.5 Maintenance and Cleaning
Whenusingstainlesssteelfurnitureandequipment,alayerofchromiumoxidepresentonthesteelsurfacemustbetaken
careof.Compoundsusedinfoodindustrywhichdisturbthepassivelayer(chromiumoxide)includecompoundscontaining
chlorides–salt,disinfectantsandacids(waterfromsauerkraut,cucumbers,acidjuices,vinegar,etc.).Wateristhemosteffec‐
veneutraliserofchloridesandweakacids.
Stainlesssteelisnotanexcepontothisruleandeachusermustbeawarethatregularcleaningandmaintenanceofstainless
productsisrequired.

5.5 Maintenance and Cleaning Connued
Cleaningshouldremovedirtandsediments,whichlefortoolongonastainlesssteelsurfacemayiniatecorrosionandtar‐
nishingofthesurface.Inahighlycontaminatedoraggressiveenvironment(seasidetowns,roomsofincreasedhumidityand
temperature,roomsrequiringfrequentuseofdisinfectants,inparcularcontainingchloridecompounds),cleaningshouldbe
donemorefrequently.Thefrequencyofcleaningshouldbeempiricallydetermined.
Inordertopreventasurfaceofstainlesssteelequipmentfrombeingdestroyedduetoinappropriatemaintenance,thefollow‐
ingguidelinesshouldbecompliedwith:
Thefollowingshouldnotbeused:agentscontainingchloridesandbleachor–underanycircumstances‐silvercleaners.
‐Steelwool,sandpaper,roughcleaners,scouring,grindingandpolishingpowders,etc.arenottobeusedastheyscratchthe
surface.
Steelpadsforscouringorwirebrushescannotbeused–theycanleavesedimentsofcarbonsteelonthesurfacewhichwill
eventuallyleadtomaterialrusng.
Firstdiscolouraonanddustsappearingduringmaterialusecanberemovedwitharegularpieceofcloth,chamoisleatheror
anylonspongeincaseofhighercontaminaons.
Ifironparclesgeneratedduringinstallaon,etc.appearonstainlesssteelcomponents,theyshouldbeimmediatelyre‐
moved.Suchparclescorrode,thustheycanbreakthepassivelayerprotecngstainlesssteel,leadingtocorrosionasaresult.
Suchsedimentsshouldberemovedmechanicallyorwithstainlesssteelcleaningagents.
‐Iftherearepitsonacomponent,theyshouldbepickledwithacidorremovedmechanically.
‐Localdiscolouraon,greasemarks–ifsmall,theycanberemovedwithsoapwater.
‐Products for cleaning stainless steel and alcohol‐based preparaons can be used for cleaning – they do not pose a threat
to the corrosion properes of stainless steel.
‐Aercleaning,itisalwaysrecommendedtopolishthesurfacewithadrypieceofcloth.
Thetablebelowpresentsthemostfrequenttypesofcontaminaonsandmethodsofhandling:
Thefrequencyofcleaningcomponentsmadeofstainlesssteelisindividual–italldependsonthedegreeofwearandcontam‐
inaon.Itshouldbedoneinfrequentintervalssoastoreducetheriskofstainlesssteelcomponentrusng.Thefrequencyof
cleaningofstainlesssteeldevicesisanalogoustothefrequencyofcleaninghouseholdsinks,stainlesssteel.
