Wet Corrosion
Alloy 309 is not designed for service in wet corrosive environments. The high carbon content, which is present to enhance creep properties, has a detrimental effect on aqueous corrosion resistance. The alloy is prone to intergranular corrosion after long term exposure at high temperatures. However, due to its high chromium content (23%), Alloy 309 is more corrosion resistant than most heat resistant alloys.
CHEMICAL COMPOSITION 309, 309S AND 309H STAINLESS STEEL PLATE
The only chemical difference between 309, 309S and 309H stainless steel plate lies in the carbon content. 309 is comprised of at most 0.20% carbon. 309S is made up of no more than 0.080% carbon and 309H stainless steel is made up of between 0.04% and 0.10% carbon. 309, 309S and 309H all contain 60.0% iron, 23.0% chromium and 14.0% nickel. They also contain 2.0% manganese and 1.0% silicon, 0.045% phosphorous and 0.03% sulfur.
