Austenitic and ferritic-austenitic duplex stainless steels Corrosion test in nitric acid medium by measurement of lossin mass Huey test Part fn Search all products by.

Over-heating of the test piece shall be avoided.

The test piece shall be bent to at least 90 over a mandrel with a radius not exceeding the thickness ofthe test piece. This second edition cancels and replaces the first edition ISO NOTE It is important to note that the result of the corrosion test is only strictly valid for the corrosive medium used in thetest.

The solution shall be maintained at boiling 20 h 5 h. The retained surface shall form the convex side of the test piece after bending. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work.

Each member bodyinterested in a subject for which a technical ido has beenestablished has the right to be represented on that committee. In the case of the chemical preparation, it shall be necessary to ensure in advance that intergranularcorrosion does not occur due to the preparation.

This heat cycle,which may provoke sensitization to intergranular corrosion, mayoccur during hot-forming forging, rolling as the result of incorrectsolution treatment or during a 36512- operation. The distance between theplatens after flattening, measured under load, shall rn no greater than the following value, H, inmillimetres: The test pieces are embedded in electrical gradecopper filings on the bottom of the flask.

Unless em stated on the order,the method of preparation shall be ej to the manufacturer and shall be recorded in the test report.

Dstu en iso 2 Business. The work of preparing International Standards is normallycarried out through ISO technical committees. 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.

Ferritic, austenitic and ferritic-austenitic duplex stainless steels Corrosion test 351-2 media containing sulfuric acid1 ScopeThis part of ISO specifies methods for the determination of the gs to intergranularcorrosion of ferritic, austenitic and ferritic-austenitic duplex stainless steels in media containing sulfuricacid.

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 copper filings may be reused if they are cleaned in warm tap water after each test. It also specifies the purposes which may be assigned to the test. Worldwide Standards We can source any standard from anywhere in the world. Tubes with up to 60 mm outside diameter shall be subject to a flattening test.

ISO consists of the following parts, under the general titleDetermination of resistance to intergranular corrosion of stainlesssteels: Take the smart route to manage medical device compliance. The solution shall be maintained at boiling during 20 h 5 h. 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.

The test pieces are firstlyimmersed in the cold test solution following which the solution is brought to the boil, from which pointonwards the test duration commences. It constitutes a basis for estimating the resistance to intergranular corrosion but may not be used to check resistance toother forms of corrosion general corrosion, pitting, stress corrosion, etc.

Cracking that originates at the edge of the specimen should be disregarded.

NOTE A determination of the weight loss may be ieo as a complement to the bend test or the flattening test for tubeswith up to 60 mm outside diameter according to 5. This should be achieved by micro examination ofsamples of each steel grade tested.

The test methods included are: Note that more than one method may be applicable for aspecific steel grade. For cast products, the radius of the mandrel shall be no more than twice the thickness ofthe test piece. The faster, easier way to work with standards.

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. The appearance ofdeformation lines, wrinkles, or “orange peel” on the surface, without accompanying cracks or fissures,should also be disregarded.
