ASTM A182 F316/316L Weld Neck Flange,stainless steel Weld Neck flange,A182 F316L Flanges
ASTM A182 F316/F316L weld neck flanges are widely used in high-pressure and high-temperature piping systems. Manufactured in accordance with ASME B16.5 Class 150 to Class 2500, these stainless steel weld neck flanges provide superior strength, excellent corrosion resistance, and reliable performance in demanding industrial environments.
The 316/316L stainless steel material contains molybdenum, which significantly improves resistance to pitting and crevice corrosion, especially in chloride-rich and marine applications. The weld neck design ensures smooth stress distribution and enhances fatigue life, making these flanges ideal for critical service conditions.
ASTM A182 F316/F316L WN flanges are commonly applied in oil & gas, petrochemical, chemical processing, power generation, offshore and marine industries. They are suitable for various pressure classes and are available in different sizes and facing types to meet project requirements.

A182 F316 /F316L Flange composition & Mechanical Properties
f316/316L is the most commonly used austenitic stainless steel in the chemical process industry. The addition of molybdenum increases general corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the controlled addition of nitrogen it is common for 316/316L to meet the mechanical properties of 316 straight grade, while maintaining a low carbon content.
