Stainless Steel 321 is an American standard titanium containing austenitic stainless steel, according to ASTM A240/A240M-19 is a high temperature stainless steel, with excellent corrosion resistance and high temperature resistance. It is composed of iron, chromium, nickel and other elements, of which the addition of chin can improve its high temperature resistance. The density of stainless steel 321 is 7.93 g/cm ³, which is slightly higher than that of ordinary steel.

The density of stainless steel 321 is determined by its composition and structure. Among them, iron is the main component, accounting for about 70%, the content of chromium is 17-19%, the content of nickel is 9.12%, and the content of titanium is 5xC-0.8%. The difference in proportion and structure of these elements will affect the density of stainless steel 321.

The density of stainless steel 321 has a certain impact on its application. Due to its higher density, more materials are required in the manufacturing process, and the cost is correspondingly higher. However, the high density of stainless steel 321 also means that its strength and hardness are higher, and it can withstand greater pressure and weight, so in some occasions that need to withstand high pressure and weight, stainless steel 321 is an ideal material choice. At the same time, the high density of stainless steel 321 also means that its heat conductivity is poor, and the coefficient of thermal expansion is large. Therefore, in the high temperature environment, the application of stainless steel 321 needs to pay attention to the influence of its thermal expansion coefficient to avoid deformation and damage caused by thermal expansion.
