Mechanical Characteristics of our s/s welded round tubes 

– Possibility of modulating the degree of hardness according to the customer’s needs by varying the drawing process.
– Heat-treated in a controlled atmosphere to obtain constant mechanical characteristics and tube malleability.
– Possibility of obtaining high levels of hardness (HV, RM, RP02) compatible with the required material.

Finishes
– Blank annealed
– Polished after profiling
– Satin
– Cut to size by removing internal and external cutting burrs
– Washed
– Pickled
Packaging Type
– Carton boxes
– Wooden case
