摘要
In this research work, the structures and properties of four kinds of stainless steel with different Ni contents used for concentrated nitric acid are investigated using optical microscope, X-ray diffractometer, scanning electron microscope and by means of properties testing. Experimental results show that the amount of austenite in the tested steel is increased with the increasing of Ni content, and the toughness and the corrosion-resistant property are improved.
