1) Theoretical guidance values for coating thickness per surface.

2) Minimum coating mass - g/m2 refers the coating mass for each side in g/m2 according to VDA 239-100.

3) Minimum coating mass - g/m2 refers the total weight of coatings on both sides of a 1 m2 plate.

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.
