Stainless Steel Material for Sea Water Application
(OP)
there is a requirement for a range of swing check valves of different sizes with working pressure of approximately 8 kg/sq.cm for sea water application. body and internal materials are of 18-8 SMO stainless steel. is it acceptable to use this material for sea water service ? if not, any other alternatives ?

I believe RobG above, has the best advice. Additionally, I suggest that you check out the following site for materials discussions on valves, piping, pumps, etc. for seawater service.
http://marine.copper.org
and for general seawater corrosion info, try:

We can increase the surface hardness, wear resistance and corrosion resistance of titanium even further by ion nitriding.
Contact me if you need more ifo etc.

B16.34 limits temperature to 750F, and the BPV is even more conservative, however.

Sandvik 254 SMO (= UNS 31254)
(a trademark of Avesta Sheffield AB)
Also Sandvik SAF 2205 (= duplex 2205 = UNS31803) or Titanium is used, but SS316 or 304 being is normally never accepted.
Try the site www.steel.sandvik.com/
or www.avestasheffield.com/steel_grades.asp
They have specs for SMO254 and SAF2205
