I would like to ask everyone, what material is suitable for high-purity liquid hydrogen chloride?

I would like to ask my colleagues: what material is more suitable for high-purity liquid hydrogen chloride – such as 316L or duplex stainless steel, or nickel-based alloys like 625 or 825? Additionally, are there any particular things to keep in mind when designing such a medium, or any additional requirements that need to be met? Thank you all for sharing your experiences; I look forward to the responses from the experts
316L definitely won’t work. 904L is a viable choice for materials; duplex stainless steel is slightly inferior.
Why doesn’t 316L work? Could you explain it? Thank you
316L is intolerant to chloride ions and will corrode
