Corrosion of Weldments J.R. Davis

We are using sulfuric acid to maintain the pH of cooling water at our plant. When there is a danger of corrosion in the heat-affected zones of weldments, the low-carbon variety SX316L should be used. Detected defects, and stress-corrosion defects are located predominantly in the lowest part of pipeline circumfer- ence; they tend to be located along longitudinal weld seams. When there is a danger of corrosion in the heat-affected zones of weldments, the low-carbon variety SX 316L should be used. Steel welded to low alloy steel. Pitting corrosion of austenitic stainless steels and their weldments . The dimensional stability of the weldment residual stress stability. John Sedriks on page 265, page 779, and page 938; SCC - Stress Corrosion Cracking of Stainless Steel 300 series austenitic stainless steels (SS),. Stress relieving of martensitic or ferritic stainless steel weldments will simultaneously temper weld and heat affected zones, and for most types will restore corrosion resistance to some degree. : Decided the outcome of the match Mikhailov: he gave up in the end of the second period and the first half of the third. ‘� The dimensional stability: the welding residual stress over time some changes in the size of the weldment also changes. We are experiencing severe damage to the SS-316 material piping at the outlet of the sulfuric acid storage vessel. Primary coolant and the operating conditions of PWR plants can cause cracking of these nickel-based alloys and weldments through a process called primary water stress corrosion cracking (PWSCC). SX 316 also possesses excellent mechanical and corrosion properties at sub-zero temperatures.
