THE NEW INSTRUMENT FOR FISH-SCALE RISK ASSESSMENT

HELIOS 2 FISHSCALE is an innovative laboratory instrument that can measure hydrogen diffusion coefficient through any metallic sheet. HELIOS 2 FISHSCALE can be used as:

-  laboratory instrument to evaluate the fish-scale susceptibility in steel for enamelling;

-  laboratory instrument to compare enamel performance during forced fish-scale test.

The test method is based on the elaboration of the permeation curve obtained for the examined sheet metal, according to ASTM G148-97(2011) Standard. The most common technique for fishscaling assessment is that defined by the standard EN10209. The standard uses the “TH” parameter (a function of the break through time, t0) to determine the fishscale susceptibility of steels. The break through time is the simplest method to get an indication of steel susceptibility to fishscaling, anyway the method is not valid for some steels (for instance for Titanium and Boron steels). Moreover the method  is based on a partial measurement of the permeation curve, so it does not provide specific indications on steel trapping ability. HELIOS II Fishscale overcomes these limits and it is able to perform test using a chemical substances not restricted by the current REACH norm (as arsenic, or mercuric chloride, which are indicated in the EN10209:2014 Standard).

Once acquired, the signal that depends on the hydrogen flux through the examined test sample, is processed by proper mathematical codes (on by means of a dedicated panel PC) and an index that the fish-scale defect appears is evaluated are evaluated. HELIOS II 2-PERMEATION is a completely automated instrument!

Letomec offers customized instrument and consultancy to define optimal hydrogen charging conditions (current density, electrochemical solution, re-circulation of the test solution, air circulation, etc.).

HELIOS method is a part of the UNI 11734 Standard. Moreover, HELIOS method could be also part of the EN 10209 standard, which is currently under review.
