corrosion resistant stainless steel grades for distillation


I want to know which kind of austenitic stainless steel grade is the best for distilling and refluxing corrosive chemical such as sulfuric acid ,phosphoric acid, calcium hypochlorite
I need distilling sulfuric acid for making diethyl ether
phosphoric for elemental phosphorous
calcium hypochlorite for chloroform
(also please i don't want to use glass or ceramics because is fragile
i only want to use metals)

No chance of using SS for distilling sulfuric acid or refluxing hypochlorites.
Glass is your only option for this stuff.but if u want to make either u could use teflon coated steel bcoz it's less than 250'c at which point teflon softens but distilling sulfuric acid requires 300'c+ so teflon coated steel is out.im guessing phosphoric acid is no good for steels but I'm not sure.naocl and caocl will probably fuck steel too.
Glass is what u need.its that simple unless you have the money to get platinum metal
flasks made or glass coated steel like industry uses but this cost will be astronomical
compared to glass.just buy the glass.

Have any of the questions you keep asking actually gotten you to do any actual experimentation ?
Are your questions an elaborate way of trolling ?
If so, could you elaborate on how it gets you off to start empty debates among users ?

As for your questions, one of my suppliers carries Platinum labware. They also have steel alloyed with Palladium or Rhodium or both.
Nothing fancy, usually around 15% PGM. Not expensive at all !

That's the way to go if you want only ONE set of equipment.

You don't reflux hypochlorites for chloroform!

If you want to save money then go to eBay and get cheap labware from Deschem.

Even if you break it 20 times it wont cost you as much as a custom piece of equipment made from special steel.

I imagine that this advice will fall on deaf ears until the next silly question
