請問一下SUS321的材質

Question

請問有人知道SUS321的彈性模數 質量密度和蒲松比嗎?

Answer 1

SUS321的彈性模數 = 193 - 200 GPa = 28000 - 29000 ksi。
SUS321的質量密度 = 8g/cc = 0.289 lb/in3。
SUS321 沒有蒲松比。

抱歉，打錯了，SUS321 有蒲松比。SUS321 蒲松比 = 0.30參考資料：D. E. Gray, American Institute of Physics Handbook, 3rd ed., chapter 3, McGraw hill, New York, 1973.

Answer 2

或許你也會需要其他資料:

Specs for plate sheet & strip: ASTM A 240, ASTM A 240 M; ASME SA-240, ASME SA-240M; AMS 5510
SubCat: Stainless Steel, T 300 Series Stainless Steel, Metal, Ferrous Metal
Material Notes:
Iron content above calculated as balance.

AL 321 is a stabilized stainless steel which offers excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800° to 1500°C. The addition of titanium stabilizes against chromium carbide formation.
