Manufacturing Technology and Material Properties of Large Size Austenitic Stainless Steel Forgings

The effects of grain size, cooling rate, and chemical composition (especially carbon content) on tensile properties, intergranular corrosion resistance and ultrasonic attenuation were studied to establish manufacturing conditions of large size austenitic stainless steel forgings. Based on these fundamental studies, large size products such as disk and flange forgings were manufactured and the verified results proved their homogeneity, excellent quality, and good manufacturing performance.
