Product Description

R30003(Co40CrNiMo) is well known for its excellent resistance to corrosive environments, elevated temperature resistance and high strength. And it is non-magnetic. Its mechanical properties are often superior to stainless steel and other nickel alloys. There are arguments that in some (medical) applications, it offers several advantages versus titanium and thus considered a replacement of titanium.


Chemical composition of Elgiloy(wt, %)

  • Carbon ... 0.15 max
  • Manganese 1.5-2.5
  • Silicon ... 1.20 max
  • Phosphorus ... 0.015 max
  • Sulfur ... 0.015 max
  • Cobalt ...39.0-41.0
  • Chromium... 19.0-21.0
  • Nickel ...14.0 -16.0
  • Molybdenum ...6.0-8.0
  • Beryllium ... 0.10 max
  • Iron... Balance 


Characters of R30003

  • Exceptional resistance to corrosion, stress corrosion cracking and hydrogen embrittlement.
  • Good fatigue strength
  • The absence of aging in service.
  • Non-magnetism.
  • Capable for application ranges of temperatures, from liquid helium (-269 ° C) to around 500 ° C.
  • Perfect passivity in contact with human tissues.
  • The ability to increase the strength of parts by hardening after forming, leading to strength levels unattainable with other materials.
  • The absence of brittleness at low temperatures (no transition temperature).
  • A maximum servicetemperature of approximately 100 ° C higher than for stainless steels.
  • Significantly superior corrosion resistance than stainless steels containing molybdenum.
  • A very high elastic limit combined with a high elasticity modulus in tension and in torsion, allows the storage and rapid release of large
  • amounts of elastic energy.

So there is no surprise that R30003 is considered a reasonable material to be used as diaphragm in a Diaphragm Valve. To make it better, Xunshi could now offer Elgiloy strip with roughness of  less than 0.1 μm. This makes it possible that our Elgiloy diaphragm to find a place in semiconductor industry.
