ASME material data

[titanproj]

Hello there,

I want to produce my boilers from SA 275 class 50, but all my calcylations are in SA 275 class 60. Does this mean I have to recalculate them all. Or is it possible to use the old calculations which are all approved by NoBo.

Many thanks in advance

You may be hard pressed to build anything out of SA-275 since this is a MT examination procedure. However,as an AI or PED Inspector I would require you to resubmit calcs. if you want to lower a stress value. If you wanted to raise it,we could talk.

Sorry about that the material should read SA 278 class 50 and 60. But I really want to know how I can get these material data sheet. With the strenght value's.
