Industry FAQs

Q: How do I choose between 316L, Duplex 2205, and Hastelloy C-276 for chemical service?

A: 316L covers general chemical service. Step up to Duplex 2205 when chlorides or higher pressures are present. Select nickel alloys like Hastelloy C-276 for severe hot mineral acids, wet chlorine, or where stainless steel fails.
