All bend tests require a tensile test machine or similar, with suitable grips and sufficient strength to bend the strongest alloy.

As 15 hours is a difficult test period in practice, and is only a minimum, conducting wn test for 20 hours overnight means that the two tests are equivalent. Where a bend test is required, the sample 6351-2 be bent over a lso of a diameter related to the specimen diameter, without any cracking, as determined by inspection under a low power microscope and a microsection in any suspicious areas. Good material should have a corrosion rate substantially less than the threshold value.

Some suggested criteria for the listed alloys are shown in Table 2, below. This document describes all three of these tests for four common standards, and describes the differences. Accept and continue Learn more about the cookies we use and how to change your settings.

Corrosion test in media containing sulfuric acid Status: Ferritic, austenitic and ferritic-austenitic duplex sio steels. It does not say what to do about duplex or super austenitic alloys.

SEP does not require ageing, although it might be required in a specification calling up this standard. These tests were introduced when the carbon content in CRAs typically hit 0. Where a standard is included in a purchase specification, isso must be followed, although it is advised that unsuitable tests, such as the Huey test for duplex and super austenitic stainless steels, are queried.


ISO is specifically for duplex and all austenitic stainless steels, and recommends ageing at two different temperatures: There are iiso number of recognised tests when it comes to the intergranular corrosion testing of corrosion resistant alloys CRA.

Samples may be rectangular or cylindrical to suit the test vessel, but where a bend test is required, ixo is suggested that the sample be a minimum of mm long. For many alloys, the onset is at 0.

Corrosion test in nitric acid medium by measurement of loss in mass Huey test. Worldwide Standards We can source any standard from anywhere in the world. The most convenient ido is often a cylinder 10mm diameter by mm long, but other dimensions are possible to suit particular product forms. The exception to this is ASTM G28 method A, where rates for the onset of intergranular corrosion are described in reference 1.

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.


This document also points out which alloys the tests are intended isso, and recommends the most appropriate test when none is specified.
