What Is ASTM A182 F316 / F316L?
ASTM A182 is the standard specification for forged or rolled alloy and stainless steel flanges intended for high-temperature and pressure service.
-
F316: Molybdenum-bearing stainless steel with enhanced corrosion resistance
-
F316L: Low-carbon version of F316, offering improved weldability and reduced risk of intergranular corrosion
For welded systems and corrosive media, ASTM A182 F316L is generally preferred.

A182 F316 /F316L Flange composition & Mechanical Properties
A182 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.
