Determination 36651-1 la resistance a la corrosion intergranulaire des aciers inoxydables. Alternatively, a welded test-piece in the as-welded condition may be tested. It does not say what to do about duplex or super austenitic alloys.
Determination of resistance to intergranular corrosion of stainless steels – Part 2: Determination 3651–1 resistance to intergranular corrosion of stainless steels – Ferritic, austenitic and ferritic-austenitic duplex stainless steels – Corrosion test in media containing sulfuric acid Pitting and Crevice Corrosion Tests according to: ISO is specifically is duplex and all austenitic stainless steels, and recommends ageing at two different temperatures: This document describes all three of these tests for four common standards, and describes the differences.
For many alloys, the onset is at 0. Test Samples Samples may be rectangular or cylindrical to suit the test vessel, but where a bend test is required, it is suggested that the sample be a minimum of mm long. Pitting and Crevice Corrosion Tests according to: This European standard specifies a method for the determination of the resistance to intergranular corrosion of austenitic stainless steels in a nitric acid medium by measurement of the loss of mass Huey test.
You may find similar items within these isoo by selecting from the choices below:. 36551-1 A was designed for austenitic stainless steels, specifically the series alloys. There are a number of recognised tests when it comes to the intergranular corrosion testing of corrosion resistant alloys CRA.
This means that carbide formation during welding is highly unlikely, and modern CRAs should easily pass one of these tests. Determination of resistance to intergranular corrosion of stainless steels – Austenitic and ferritic – austenitic duplex stainless steels – Corrosion test in nitric acid medium by measurement of loss in mass Huey test.
МКС EN ISO 3651-1:2009
Intergranular Corrosion and Stress corrosion Tests according to: As 15 hours is a 3651-11 test period in practice, and is only a minimum, conducting the test for 20 hours overnight means that the two tests are equivalent. Where a standard is included in a purchase specification, this must be followed, although it is advised that unsuitable tests, such as the Huey test for duplex and super austenitic stainless steels, are queried.
Conducting the Tests When a test has been selected, follow the detailed directions in that standard for making up the test solution, the preparation of test samples and the finish to be used.

Corrosion test in nitric acid medium by measurement of loss in mass Huey test. Take the smart route to manage medical device compliance. This test should be avoided for most CRAs, except in the circumstances described below, in section 4. None of these are identical and cross substitution of results is not possible. There are other requirements in these standards over lso that are not discussed in this document, and these should be followed, such as conducting bend tests.
For an alloy that is not listed, look for an alloy with a similar composition to a listed alloy to determine the most suitable test.
The method is applicable only to austenitic stainless steels supplied in the form of rolled or forged products and tubes and intended to be used in an oxydizing medium for example concentrated nitric acid. Find Similar Items This product falls into the following categories. The Tests Table 1 below shows the various methods for four common standards: The Huey test method C is only for molybdenum-free grades, such as L, as alloys with molybdenum show high rates of attack in this test.
Please download Chrome or Firefox or view our browser tips. The exception to this is ASTM G28 method A, where rates for the onset of intergranular corrosion are described in reference 1. Methods B and E are suggested for all grades of series austenitic alloys, while method F is suggested for cast type alloys.
Intergranular Corrosion Tests for CRAs
Table 1 below shows the various methods for four common standards: Selection of a Test Method The test methods in Table 1 were designed with specific alloys in mind, but the proliferation of new CRAs has meant that the selection of a suitable test method is difficult. ASTM G28 does not require samples to be heat treated. SEP does not require ageing, although it might be required in a specification calling up this standard. Isi no specific test is specified, Table 5 suggests the most appropriate alongside a second choice, if the first is declined.

Related international standards This standard is identical to: Acetic Acid Salt Spray. Austenitic and ferritic-austenitic duplex stainless steels.
Also Slow Strain Rate Testing could be evaluated on request. Bestimmung der Bestaendigkeit gegen interkristalline Korrosion. ISO is specifically for duplex and all austenitic stainless steels, and recommends ageing at two different temperatures:. Both of these tests should be followed by water quenching.
