Mechanical properties meet the requirements of EN 10305 (+CR2).
Chemical composition meets the requirements of EN 10305.
If other chemical elements such as Ti, Nb or V are used, the content of these elements are reported in the inspection document.
1) This requirement is not applicable provided the steel contains a sufficient amount of other nitrogen binding elements, such as Ti, Nb or V.

Surface is slightly oiled to protect it from corrosion during transportation and short-term storage. By request, tubes can be delivered dry, however in that case SSAB will not be responsible for any possible rust.
< 2.0 µm
< 2.0 µm
The tubes are not intended to undergo any heat treatment after welding and sizing as that may alter the mechanical properties of the material.
The tubes are oiled with anti-corrosive oil.
