Determination of resistance to intergranular corrosion of stainless steels. Annex A gives examples of application of the three methods on stainless steels.
The corrosivesolution may be used more than once provided it is not discoloured and that its density has not changed. In case of dispute,the duration of the test shall be 20 h. Ne also specifies the purposes which may be assigned to the test.
Essais 36512- corrosion en milieux contenant de l’acide sulfurique Title in German Ermittlung der Bestaendigkeit nichtrostender Staehle gegen interkristalline Korrosion. NOTE When an evaluation is questionable a metallographic examination of a longitudinal cross section of the test piecemay be used to detect the presence of intergranular corrosion and to measure the depth of penetration. Take the smart route to manage medical device compliance.
This should be achieved by micro examination ofsamples of each steel grade tested. The test 3651- are embedded in electrical gradecopper filings on the bottom of the flask.

Ferritic, austenitic and ferritic-austenitic 36512- stainless steels Corrosion testin media containing sulfuric acidDtermination de la rsistance la corrosion intergranulaire des aciersinoxydables Partie 2: Incase of dispute, the duration of the test shall be 20 h.
NOTE It is important to note that the result of the corrosion test is only strictly valid for the corrosive medium used in thetest. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3.
For welded tubes up to 60 mm outside diameter, the test piece shall be a full cross section of the tubeand will be subject to a flattening test see 6. The comparison of the two pieces enables it to be establishedwhether or not the cracks observed on the corroded test piece are due to intergranular corrosion.
It constitutes a basis for estimating the resistance to intergranular corrosion but may not be used lso check uso toother forms of corrosion general corrosion, pitting, stress corrosion, etc. For cast products, the radius of the mandrel shall be no more than twice the thickness ofthe test piece.

Ferritic, austenitic and ferritic-austenitic duplex stainlesssteels Corrosion test in media containing sulfuric acidAnnexes A and B of this part of ISO are for information only. The appearance ofdeformation lines, wrinkles, or “orange peel” on the surface, without accompanying cracks or fissures,should also be disregarded.
Please download Chrome or Firefox or view our browser tips. Draft International Standards adopted by the technical committeesare circulated to the member bodies for voting. Cracking that originates at the edge of the specimen should be disregarded. Determination de la resistance a la corrosion intergranulaire des aciers inoxydables. Ferritic, austenitic and ferritic-austenitic duplex stainless steelsmay be subject to such an attack when they are held at atemperature between about C and 1 C.
The faster, easier way to work with standards. The test methods included are: Ferritic, austenitic and ferritic-austenitic duplex stainless steels Corrosion test in media containing sulfuric acid1 ScopeThis part of ISO specifies methods for the determination of the resistance to intergranularcorrosion of ferritic, austenitic and ferritic-austenitic duplex stainless steels in media containing sulfuricacid.
The test piece shall be bent to at least 90 over a mandrel with a radius not exceeding the thickness ofthe test piece.
This heat cycle,which may provoke sensitization to intergranular corrosion, mayoccur during hot-forming forging, rolling as the bz of incorrectsolution treatment 36512 during a welding operation. Corrosion test in media containing sulfuric acid. The test pieces are firstly immersed in the coldtest solution following which the solution is brought to the boil, from which point onwards the testduration commences. Tubes with up to 60 mm outside diameter shall be subject to a flattening test.
For welded tubes with outer diameter over 60 mm, the test pieces with length of at least 50 mm andwidth of at least 20 mm are prepared as shown in figure 4.

NOTE Corrosion rates are expected to increase if all the ferric sulfate is used up. ISO consists of the following parts, under the general titleDetermination of resistance to intergranular corrosion of stainlesssteels: The methods are applicable to stainless steels supplied in the form of cast, rolled or forged productsand tubes and intended for use in a mildly oxidizing acid medium for example, sulfuric acid, phosphoricacid.
The work of preparing International Standards is normallycarried out through ISO technical committees. Find Similar Items This product falls into the following categories. The copper filings may be reused if they are cleaned in warm tap water after each test.
NOTE In the field of application of this test, intergranular corrosion may beconnected with the presence along the grain boundaries of a chromium-depletedregion due to precipitation of chromium carbides, sigma phase or otherintermetallic phases.
