steel low temperatures standards
steel low temperatures standards
(OP)
Hello,
Can anyone please explain me how can I know the minimum ambient temperature According to steel standards? for example s235 and st37.
If the steel passes impact test in (-)20°c, according to the standards, that means the steel can stand at (-)20°c and not below?
Or - I can choose the minimum temperature according to the steel uses, load, and mechanical properties at specific temp.? In this case the standards are only for recommendation?
Thanks.

denlow60 - for now I don't have in reach the EN 10025:1-5.
But from Google search I didn't find any help how to determine the minimum ambient temperature that steel profile or plate can be use.
moltenmetal - if I understand you correctly I can use "ordinary" steel, like s235jr, but use thicker plate or profile.
Maybe it's stupid question but why we need the impact test that EN require?

In pressure vessels, for low ambient temperature or autorefrigerating gas applications for pressure vessels and piping, low temperature steels or even stainless steels are required- no option. But where it gets silly is where people start specifying low temperature steels for services containing water...
