Question Ishimoto 2009/6/4(Thu) 14:33

In my opinion, stainless steel SUS304-CSP; Spring steel SUP10-CSP; Beryllium C1700, C1720; Nickel silver C7701 are all excellent materials as spring materials. Can you tell me the Young’s modulus and density of each?
*SUS304（EQ to S30400 by ASTM, X5CrNi1810 by DIN, L-No6X5CrNi 18-9 by ISO ）
*SUP10（EQ to 6150 by ASTM, 50CrV4 by DIN, 51CrV4 by ISO)

Thank you for writing to us, Ishimoto!
For each material’s Young’s modulus, we would appreciate it if you could check the URL below. http://www.tokaibane.com/tech/tech_info_leaf.html

The density is as follows.
Stainless steel SUS304-CSP → 7.93 g/cm^3
Spring steel SUP10-CSP → 7.85 g/cm^3
Berylium C1700, C1720 → 8.30 g/cm^3
Nickel silver C7701 → 8.70 g/ cm^3 or more
