Coating and Surfaces

Surface designation and general usability

Designation
Designation
UC
Definition
Uncoated (Hot rolled and pickled, HR, S2)

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.

Surface roughness, Ra

UC, HR
Ra value
< 2.0 µm

Delivery Conditions

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.

Fabrication and Other Recommendations

For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
