    NOTE Welding of tubes of these grades does not require special techniques but
    care should be taken and welding should be carried out in accordance with the
    guidance given in the appropriate British Standard for welding,e.g. BS 5135.
    aIf rimming or semi-killed steel is used for grade 2,the carbon content may be
    increased to 0.19%,and if used for grade 3,to 0.23%.bGrain refining elements
    may be added to this grade at the option of the manufacturer.
