The response of Mr Amarjit Singh is correct. I would like to add a bit of additional info on to this.
API-582,Recommended Practice-Welding Guidelines for Chemical,Oil and Gas Industries , clause 6.2 (On Dissimilar metals welding) privides a table and further recommendations on dimmilar metals welding in petrochemical environment. You may download the draft for Ballotting (free copy) from API website or alternatively buy it through API.

Dear Mr.Shanmugam
Since the operating temperature is below 325 deg C , you can use E309L/ E309MoL consumable. If the operating temperature is more than 315deg C , then have to use inconel electrodes e.g. ENiCrMo-3.
