Issues related to the grades of stainless steel materials

This post was last edited by FORREST_GUMP on 2015-11-6 20:11. Should stainless steel heat exchange tube material be S30403 or 00Cr19Ni10? (Selected when calculating SW6). Some people say that 00Cr19Ni10 should be used for pipes, while S30403 is suitable for forgings and sheets. So the question is: is this statement correct? How exactly should it be understood? All the amazing Sichuan friends. . . It’s up to you guys.
Numbers and codes are now written on the drawings. However, when using SW6 for calculations, it is necessary to select the grade option for the pipe, as the allowable stress specified for the pipe code applies to welded pipes and is lower than that of the grade-based value.
In that case, the material names in the calculation sheet will not match those on the drawings. What should be done? Is this considered an error?
Once the calculation sheet is ready, just manually change it to numerical codes
The forging standards use numerical codes. . S30403。 . . And pipe S30403 is also suitable; 00Cr19NI10 is also okay
Both of these should work, I think. I’ve learned the specifics! Pipe S30403 works as well, and 00Cr19NI10 is also acceptable
For upper floors, it’s different – the stress required when choosing S30408 versus 0Cr18Ni9 is not the same. I usually choose S30408 for plates and 0Cr18Ni9 for pipes. You can try entering it by yourself.
