In the present paper, the effect of artificially produced pit-like defects on the strength of members made of AISI 410 martensitic stainless steel were investigated. Compressor blades in power generation industries made of AISI 410 stainless steel commonly suffer from pitting corrosion. Well-defined pit-like defects were artificially produced on various specimen and strength tests were conducted. AISI 410 stainless steel microstructure shows a typical body-centered tetragonal (bct) structure. Strength tests analysis established yield strength of 547 MPa for Case 1 (max depth-max diameter) whereas a yield strength of 585 MPa for Case 2 (min depth-min diameter). In addition, strength and elongation of the artificially produced pitted tensile specimen gradually decrease with the increase of the area lost due to artificially produced pits. Â
