Features
- Molybdenum alloyed, excellent pitting resistance against chloride, salt spray, seawater and mild chemical media, much better than 304
- Good formability and weldability; continuous service temperature ≤300℃
- Slightly lower work-hardening rate than 304. Higher cost. Mo content makes it gummy during machining.
Applications
Marine equipment, swimming pool parts, chemical machinery, waste water treatment, medical & pharmaceutical equipment, seawater filters, coastal outdoor enclosures, salt-spray cabinets, high-end sanitary hardware
Material Selection Guide
Grade selection guide 316: Standard grade, slightly higher strength, for non-frequent welding 316L: Low carbon, ideal for heavy welding, pharma & clean process 304: General corrosion resistance, not chloride resistant, cost-effective
