Stainless steel alloy to pipe dilute sulfuric acid

We want to replace the existing MS pipe line being used to handle dilute sulfuric acid of concentration 9% to 10% at a temperature of 70 to 80 °C and at a pressure of 3 to 4 bar. Please suggest us the all possible stainless steel alloys to replace the existing MS pipe. The suggested alloy should not be expensive and should be weldable to do any repair jobs at site. the present pipe size is 200 mm.

Dear Mr.js c Rao,For handling dilute sulfuric acid in your pipe line rather than metal alloy I would suggest you internal coating of the pipeline with a chemical resistant coating.
