摘要：
Provided is an austenitic stainless clad steel plate having excellent j oinability between a cladding metal and a base metal in addition to excellent corrosion resistance, especially sensitization resistance characteristics, and a method for producing the austenitic stainless clad steel plate.
An austenitic stainless clad steel plate has a cladding metal and a base metal formed by being stacked to the cladding metal. The cladding metal includes a composition that contains, by mass%, C: 0.020% or less, Si: 1.00% or less, Mn: 2.00% or less, P: 0.045% or less, S: 0.030% or less, Ni: 12.00 to 15:00%, Cr: 16.00 to 18.00%, and Mo: 2.00 to 3.00%, and the balance is Fe and incidental impurities. The cladding metal includes an austenite grain structure of a partially recrystallized structure or a recrystallized structure. The austenitic stainless clad steel plate has a shear strength of 300 MPa or more.
