1.4307 TP304L EN10217-7 6 X 1.0MM Bright Annealed Welded Precision Stainless Steel Tubing
1.4307 - AISI 304L is the standard for the austenitic grades of stainless steel due to its good corrosion resistance, ease of formability and fabrication coupeld with its aesthetic appearance in the polished, ground and brushed conditions. Since 1.4307 - AISI 304L is not resistant to intergranular corrosionin the welded conditions, 1.4307 should rather be specified if welding of larger sections is required and no solution annealing treatment after welding can be performed. Surface conditions plays an important role in the corrosion resistance of this steel with polished surfaces exhibiting far superior corrosion resistance compared with rougher surfaces on the same material.
304L/4307 Welded Precision Stainless Steel Tubing is a low-carbon alternative to 304/4301. The lower carbon content minimizes carbide precipitation as a result of heat input, for example during welding, giving improved resistance against intergranular corrosion. It’s suitable for a wide variety of applications that require good formability and weldability, and can be delivered with a variety of surface finishes.
