PROGRESSO
Low-carbon 316L welded stainless steel pipe with molybdenum addition for superior chloride and seawater corrosion resistance. Bright annealed, pickled and polished as required.
316Tubo saldato a L is formed from a pickled 316L strip, welded longitudinally, then bright annealed. IL “l” means extra low carbon (≤ 0.03 %), which resists carbide precipitation and intergranular corrosion after welding.
Why 316L over 304?
