We notice that more and more glass beer containers switch to stainless steel kegs and growlers . This change is due to the fact that stainless steel materials present more advantages than the others. But what is stainless steel ? Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium is very resistant to corrosion , moisture and rust . Stainless steel is divided into 4 main categories. People use stainless steel for diverse applications. However ,the one who will retain our attention is the food-grade stainless steel . These have the highest corrosion resistance .
Food grade stainless steel comes into different categories .But the most recommended are the 300 and 400 stainless steel series . 300-series contains both chromium and nickel. With about 18% and 8% or more by mass ( Example :18/8, 18/10, etc.) . 400-series are chromium paired with a small number of other elements. I strongly suggest you to go through this article of the European stainless steel development association . It will give you a full understanding about stainless steel and its use ( http://www.worldstainless.org/Files/issf/non-image-files/PDF/Euro_Inox/WhenHealthComesFirst_EN.pdf )
