These grades are manufactured to the highest quality standards in order to meet the most stringent specifications for use in welded tubes and pipes. The reference standard is API 5L (American Petroleum Institute).
Specific requirements such as HIC (hydrogen-induced cracking) resistance or high ductility at low temperature can also be guaranteed.
These grades have very high tensile strength and toughness at very low temperatures. Furthermore, they offer excellent weldability because of their exceptionally low carbon equivalent value.
These steels are used to manufacture pipes for the transport of gaseous or liquid materials such as water or oil.
The chemical properties specified are in accordance with the requirements of API 5L for PSL2-type pipes; other properties are available on request.

The mechanical properties of the pipes will depend on:
The evolution of the mechanical properties - and in particular of the difference in yield strength between the sheet and the pipe - is specific for each process. It is therefore very important to indicate both the forming and the welding process as well as the aforementioned sheet/pipe difference. An agreement between ArcelorMittal and the client on the mechanical properties to be guaranteed must be reached prior to the delivery.
The mechanical properties specified, in the thickness ranges proposed and supplied as described, enable the requirements of API 5L PSL2 standard to be met on the finished pipe.
HIC: According to NACE-STD-TM-0284
X: Possible on request
