Steel for large diameter pipes steel plate steel plate

Also referred to as Atmospheric Corrosion Resistant Steel, this product is seen as an inexpensive and highly effective material to be used in structural applications which are exposed to the atmospheric elements.

The steel oxidises with pollutants in the air forming a thick layer of rust – this formation acts as a protective layer which prevents the steel from corroding. The layer constantly regenerates and forms over time.

1) For a reduction by 0,01 % each below the max. carbon content an increase of the manganese content
    by 0,05 % above the max. value is permissible, the increase being limited to 0,2%
2) For a reduction by 0,01 % each below the max. carbon content an increase of the manganese content
by 0,05 % above the max. content is permissible, the increase being limited to 1,40 % for
    steel grades = X 52, to 1,60 % for steel grades > X 52, and 2,0% for steel grade X 70.
3) A max. carbon equivalent
    CE = C + Mn/6 + (Cr + Mo + V)/5 + (Cu + Ni)/15
   can be agreed upon. CE is determined for the check analysis only.
4) 0,015 ≤ Altotal< 0,060; N = 0,012; Al/N = 2;

5) The total V, Nb, and Ti - contents must not exceed 0,15 %.

Large-diameter pipes Cold-forming
Cold-forming processes such as bending, flanging, expanding etc. can be easily carried out. A subsequent heat treatment is usually unnecessary.
Large-diameter pipes Heat treatment
Normalised and stress relief annealing of the normalised rolled steel grades is possible. Since normalised and stress relief annealing above 580 °C of the thermomechanically rolled steel grades may cause a decrease of yield point and tensile strength, both heat treatment methods should be avoided.
Large-diameter pipes Welding
Observing the general technical directions, the steel is weldable by hand as well as mechanically according to all electric processes. A preheating of the steel for welding purposes is not necessary if normal laying conditions prevail. It has to be taken into account that the behaviour of this steel during welding and thereafter depends not only on the material but also on the conditions of welding the pipeline and may thus be impaired.
