Series: ASM Failure Analysis Case Histories
Publisher: ASM International
Published: 01 June 2019
DOI: 10.31399/asm.fach.design.c9001223
EISBN: 978-1-62708-233-4
... Abstract The corner of a welded sheet construction made from austenitic corrosion-resistant chromium-nickel steel showed corrosive attack of the outer sheet. This attack was most severe at the points subjected to the greatest heat during welding. Particularly large amounts of weld metal had...
