제 목 : fine grain practice material
The only calculations that may change are the use of the material
for lower temperatures. For a material to move from Curve B to
Curve C it must be normalized AND produced to fine grain practice.
Material produced to a fine grain practice is normally used for
moderate to low temperature service because the toughness of
the material is enhanced. Fine grained steel, which is steel
that contains a smaller grain size, would help regarding exemptions
to impact testing in the Code.
