In high temperature service lines of 1000 deg. F which would be a preferred bolting material between A193 B8 Cl.2 and A 453.
I have seen both these bolting materials being used at these temperatures at different occasions hence got confused. Is there any upper limit of temperature beyond which we should go for A453 as its expansion co-efficient is similar to austenitic stainless steel?
Can any one please guide in selection of bolting material?

Harsha Bhat.
