High resistance to high and low temperatures, corrosion when exposed salt water alkaline media, wear, elongation, paramagnetism are all characteristics of austenitic nodular cast iron. However, less research has been done on the fatigue Therefore, objective this study is determine iron compare them those different types The used in (EN-GJSA-XNiCr20-2) was alloyed with 20% nickel 2% chromium create an matrix. Light metallographic microscopy examine microstructure. A tensile test, impact bending a Brinell hardness test were mechanical properties material. Fatigue tests under sinusoidal cyclic push-pull loads at room temperature obtain Wöhler curve limit. results these compared irons matrixes, namely ferrite-pearlitic pearlite-ferritic irons.
