Re: Is it better to use a Hastelloy C alloy or 316L stainless steel?17 November 2014 at 7:57am Last edited: 17 November 2014 at 7:58amIt 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
