Fatigue strength of welded joints in stainless steel plate and stainless-steel-clad mild steel plate, which is important in ensuring a high level of reliability as regards the chemical tanker structural integrity, was studied and evaluated by the authors, with the results as capsulized below. (1) Butt joints produced in stainless steel plate were found to offer nearly as high a level of fatigue strength as those produced in HT50 high-tensile ship hull steel plate when tested as-welded, in the atmosphere or in sea water environment. (2) Load-carrying type cruciform joints produced using stainless steel plate and stainless-steel-clad mild steel plate were also found to be nearly equal in fatigue strength to those produced using HT50 high-tensile ship hull steel plate when tested as-welded in the atmosphere.
