What are the operating temperature ranges for 20# carbon steel and 16Mn (Q245)?
Thread Content
As the title suggests: What are the operating temperature ranges for 20# carbon steel and 16Mn (Q245)? Implement that standard?
Most of it can be found; I work with equipment related to material 150
The material mentioned by the poster should specify whether it is a pipe or a forged part; to find out the applicable temperature, one can check the design standards used.
What are you used for? . Then go and check the design specifications for that thing. .
In 150, 20# generally refers to the material of low-carbon steel pipes, while Q245R and 16MnR (now renamed Q345R) generally refer to carbon steel and low-alloy steel plates. The specific operating temperatures can be found in Chapter 150.2, Material 1.
It’s pipes; since the temperature range is quite large, I want to know the operating temperature ranges for pipes made of these two materials
Okay, thank you. I’ll check the standards
Containers and pipes have different requirements. For pipelines, 20# has a minimum of -20 degrees. The minimum for 16Mn is -40 degrees. Container 20# can only be at 0 degrees. The specific values can be found in the standards. I only remember it to be more or less like that.
