Constant extension rate tensile tests on 304L stainless steel in simulated hazardous low-level waste
New waste tanks which handle hazardous low-level waste were proposed to be constructed in H-area. The candidate material for the tanks is AISI Type 304L (304L) stainless steel. Constant extension rate tensile (CERT) tests were conducted to assess the susceptibility of 304L to stress-corrosion cracking (SCC) in these waste solutions. The tests demonstrated that 304L was not susceptible to SCC in simulated wastes. Based on these tests and previous pitting corrosion studies 304L is a suitable material of construction for the new tanks. Comparison tests in the same simulants were performed on A537 carbon steel (A537), a material that is similar to material of construction for the current tanks. Stress-corrosion cracking was indicated in two of the simulants. If carbon steel tanks are utilized to handle the hazardous low-level wastes, inhibitors such as nitrite or hydroxide will be necessary to prevent corrosion.
