CO2 fragilizes steel used in beverage bottles ?
(OP)
hi folks, any comment or literature reference would be appreciable.
I would like to know if the CO2 inside the Beer bottles or any other gaseous beverage can diffuse and fragilize the steel, even under very long exposures. I am talking about steel bottles either made by welding or deep drawing.
Thank you for your time,
Maleck

Hg embrittles aluminum. Better drink quickly.

In the USA, the majority of beverage containers are manufactured from Al alloys. However, outside the USA, it is about 50 % Al and 50 % steel.

I worked for a can manufacturer - steel cans are produced in large quantities.
Ken,
Yes, all beverage cans are coated internally. Typically, it is an acrylic-epoxy blend.

I would not worry about "fragilizing" of your steel cans due to the presence of CO2 due to diffusion of CO2 into the steel. I would be thinking more along the lines of corrosion due to the acidic liquid inside the can.

A multivariable analysis approach was used in the following study:
"A Neural Network Model for CO2 Corrosion of Carbon Steel" by Srdjan Nesic and Miran Vrhovac, J. Corros. Sci. Engr., vol 1 (18 March 1999): http://www.jcse.org/Volume1/paper6/v1p6.html
The corrosion reactions and the models & experimental results of others are given. The only accurate models are for the laboratory case of bare steel corroding in pure CO2 saturated water ("worst-case" corrosion). But reality is more complicated owing to factors such as
formation of protective surface films,
presence of the hydrocarbon phase,
presence of corrosion inhibitors,
presence of glycol or methanol,
condensation in wet gas transport,
multi-phase flow,
steel type,
corrosion history, etc.
This study's artificial intelligence model gives a better data fit than the other models.
