These heat treatments are identical to those described in the corresponding tube
standards.
b
For these steel grades it may be necessary in the case of wall thickness T above
25 mm or T/D >0,15 to apply quenching and tempering in order to achieve the intended
structure and material properties. The decision shall be left to the discretion of the
manufacturer but shall be stated to the customer at the time of enquiry and order. Steel
