The Mo Series (316 / 316L / 316Ti / 317L) is engineered for enhanced corrosion resistance, especially in:
Marine environments
Chloride‑rich conditions
Chemical processing
Industrial corrosive atmospheres
Molybdenum (Mo) significantly improves resistance to pitting and crevice corrosion, making this series one of the most reliable stainless steels for harsh environments.
Each grade serves a specific purpose:
316 — Standard Mo‑Alloyed Stainless Steel
Excellent resistance to chlorides and chemicals
Widely used in marine and chemical industries
316L — Low‑Carbon Marine Grade
Lower carbon improves weldability
Reduced carbide precipitation
Ideal for welded tanks, pipes, and pressure vessels
316Ti — Titanium‑Stabilized Mo Stainless Steel
Ti stabilization prevents intergranular corrosion
Suitable for high‑temperature and welded structures
317L — High‑Mo Corrosion‑Resistant Grade
Higher Mo content than 316/316L
Superior resistance to aggressive chemicals
Ideal for chemical processing and high‑corrosion environments
