  The other material which can be used is Manganese ,Chromium and Molybdenum (34Mn2V, 30CrMo, 34CrMo4 ).

  I need some materials with yield strength>200Mpa and density<7g/cc.
  Some other constraints are - corrosion resistance & stability at high temperatures(around 150 degree celsius).

  Nickel Steel alloys are basically Stainless Steels. Stainless Steels have Yield Strength of about 600Mpa and density of 7-8g/cc. So, it is similar to the present material which is Si-Mn steel and won't result in any significant weight reduction, if implemented.

  There are many fibre reinforced composites that may stand your duty. PEEK is suitable but expensive.
  You can look at ULTEM - Polyetherimide resin from SABIC. It has a yield strength close to what you want, excellent high temperature properties and a very low density.

  There is a software called CES Edupack, I dont know if you have heard of it but it can be used to select materials based on criteria you specify. I am not sure if there is a trial version out there but if you can get your hands on it it would help you.

  Yes, I came to know about that software in 'Material Selection in Mechanical Design' book by Michael Ashby. While searching for it on google, I found another useful website - matbase.com which also allows to search for materials according to specified criteria. Anyways, thanks for your suggestion.
