Why this combination

Why SS 316L in plates

Carbon 0.030% max for weld-zone corrosion resistance2–3% molybdenum for chloride pitting resistanceCommonly dual-certified SS 316/316LDefault choice for welded pharma, chemical and marine equipment

Fabricators choose SS 316L plate for heavy welded equipment in corrosive service because it needs no post-weld anneal. Dual SS 316/316L plate keeps 316's code design stresses.

For higher chloride or acid levels, SS 317L, SS 904L or duplex 2205 plate are the next steps.
