Standard Specification for notch toughness Requirements for normalized steel plates for pressure vessels
|Publication Date:||9 May 1968|
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.
