KEY FEATURES AND APPLICATIONS 316L is for welding austenitic stainless steel of type 18 Cr 12 Ni 2.0 Mo or similar molybdenum allotted acid resisting steels. The filler metal is also suitable for welding titanium & niobium stabilized steels such as ASTM 316Ti in cases where the construction is used at temperature not exceeding 400C. The higher silicon content improves bead appearance, better arc stability, weld metal flow. Excellent resistance to corrosion, pitting and intergranular corrosion in general and dilute acidic conditions. The resistance to intergranular corrosion is good in chloride containing environments too. The PRE (Pitting Resistance Equivalent) is about 25
