Body - WCB
Trim - 316
they are looking for 1/2",1",2",4" and 6". Qty less than 30Pcs total combine.
i told him, 316 is made up of 16Chrome-12Nickel-2Moly, but he insist of using carbon steel with nickel chrome plating.
I seriously dont understand why, i asked them is it the cost issue?
From our view as a manufacturer, making afew pieces with carbon steel+ nickel chrome plating will be more expensive.
He did not tell me any reason, i also wish to help him.
Just wonder any expert know why? or i am just wasting my time with a client that dont understand anything?
Client : from a well known shipyard.

Either way, it is always best not to deviate from customer datasheet unless it is a ridiculous request because as a valve vendor you will never know fully all considerations by the client. The person you are dealing with may not know it as well as he could just be the procurement guy inheriting the datasheet.
Cost impact shall either be mentioned up-front during quotation stage or presented as a cost impact if it is a change request by customer.
