Dear teacher, is it reliable to use 4130 alloy steel in low-temperature environments? Are there any other materials that can withstand low-temperature environments?

This is structural steel, right? It’s rarely used in pressure pipelines. Is there any material standard? It can be checked through the relevant standards

Applied to the oil industry, for things like tees and crosses; there are concerns that 4130 steel does not perform well in low-temperature environments

We haven’t used this material before. Is there a standard number? It seems that this material isn’t listed in the standards for pressure pipelines GB/T20801; however, both 20801 and 50316 specify minimum operating temperatures
