Dear Members,
In general, we all know based on description given in ASTM of A671 & A672 that A671 is used for atm. & low temperature service & A672 for H.P. service at moderate temperature.
However, if we compare the details e.g. A672 Gr.C60 & A671 Gr. CC60; the raw material plate used is same for both pipes & final mechanical properties is same.
Heat treatment is same.
Can any one explain or comment if A672 Gr.C60 with Suppl. req.S2 can be used for Low temp. service & why?
