Problems with the use of low-temperature steel plates
Thread Content
As the title suggests, in the use of cryogenic equipment, aluminum alloys or austenitic stainless steels are generally used – why isn’t 06Ni9DR used? I see there are many cases where the value is above 540 MPa; there are also weldment tests and impact tests. Are these very costly? Stainless steel can cost almost 20,000 per unit, while this low-temperature steel costs less than 5,000 – why is it used so rarely?
Okay, I get it. I didn’t check the standards carefully enough
