According to NACE Recommended Practice RP-0391 "Materials for the Handling and Storage of Commercial Concentrated (90 to 100%) Sulfuric Acid at Ambient Temperatures", either of these materials of construction should work for 98% sulfuric acid under the conditions you have described.

    It is certainly better to use hastelloy c alloy , preferabbly uns10276 for your application due to the nickel content of hastelloy being higher in hastelloy. SS316L will do okay as well, but for critical application and longetivity of the project, you must go for hastelloy. Thanks Jay MEHTA Kinnari

    Hi!you should go for Hastelloy C4 only for your application,as in Hastelloy the nickel content is more,Hastelloy C4 is bit expensive compare to Stainless Steel 316,so it can handle more pressure as well far better over stainless Steel 316 in Electromagnetic feild
