Product Overview
Introduction to ASTM A182 F316 Flanges
ASTM A182 F316 is an austenitic stainless steel grade containing molybdenum, which enhances resistance to pitting and crevice corrosion, especially in chloride environments.
F316 flanges are widely preferred over 304 due to:
- Better corrosion resistance
- Improved performance in harsh environments
- Higher durability in marine and chemical industries
These flanges are ideal for critical piping systems where corrosion resistance is a priority.
Key Features
Excellent resistance to corrosion & chemicals
Suitable for chloride and marine environments
High strength and durability
Good weldability and fabrication
Performs well at high temperatures
Long service life
