Description / Abstract:
This Specification2 covers steel plates for use in
welded pressure vessels that are to operate at low
temperatures. the classes of plates covered by this
specification shall conform to all requirements of the ASTM
specifications for the particular grade referred to in Table I in
addition to the requirements of this specification *See Note 2 in
section 2). It is desired that the steel supplied under this
specification be made to fine grain melting practive.
Note 1.-It should be recognized that fabricating processes, such
as forming and welding may affect the impact properties of steel so
that the impact properties of the plast in a fabricated pressure
vessl may differ from the impact properties of the plate as
tested.
2 For ASME Boiler and Pressure Vessel Code
applications see related Specification SA-300 in Section II of that
Code.
