Mechanical Properties of Forged Stainless Steel 321 Valves(Part One)
Abstract Nuclear valves often adopt forged stainless steel 321 as the valve body material in China. Stainless steel 321 forging billets manufactured by heating once and twice are introduced in this article. Mechanical properties of forged stainless steel 321 valves with the two processes are compared and the impact of the heat treatment on the mechanical properties of the two forging billets are further studied. Research shows that stainless...
