Determination of diffusible and total hydrogen concentration in coated and uncoated steel using melt and solid extraction techniques: Part I.

It is essentially to know the bulk hydrogen concentration in various types of steel because it indicates the amount of hydrogen that can be trapped by the different alloys of steel. This information leads to more knowledge about the interactions of steel alloys with hydrogen containing environment and stability of the steel material during usage. To get this information precise analytical methods are necessary.
