316L S31603 SUS316L stainless steel weld fittings stub end
In general, the Type 316 grade can be considered equally good in a given environment. A notable exception is intergranular corrosion in the heat-affected zone on welds and susceptible alloys in sufficiently corrosive environments. In such media, Type 316L is more suitable for welding conditions than Type 316 because the low carbon content increases resistance to intergranular corrosion.
Molybdenum’s Type 316 alloy can handle water with chloride levels up to about 2000 ppm. Although this alloy has had mixed results in seawater (19,000 ppm chloride), it is not recommended for such applications.
316 alloy has excellent weldability and good machinability. Good Corrosion Resistance – Excellent pitting resistance and good resistance to most chemicals involved in industries such as paper, photography and textiles.
