All appropriate measures shall be taken to prevent the addition of undesirable elements from scrap or other materials used in the steelmaking process.

b The content of these elements need not be reported unless intentionally added to the cast.

c Option 2: In order to facilitate subsequent forming operation, an agreed maximum copper content lower than indicated and an agreed specified maximum tin content shall apply.

d This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements which shall be reported.

a +N = Normalising, +NT = Normalising + Tempering, +QT = Quenching + Tempering (air or liquid), +I = Isothermal Annealing.
b Normalising includes Normalising Forming.

c 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 tubes treated in such a way shall be designated by the steel name supplemented by the symbol +QT.
