About SS Flanges
Stainless steel (SS) flanges are typically manufactured from austenitic stainless steel alloys most commonly grades304 and316 whose corrosion resistance and mechanical properties derive from their precise chemical compositions. Below is a summary of the key alloying elements and their typical weight percent ranges for these two grades:

Notes:
-
Grade304 ("18/8 stainless steel) is the most widely used SS flange material, valued for its general purpose corrosion resistance and formability .
-
Grade316 adds molybdenum for enhanced resistance to chlorides and marine environments, making it preferable for more aggressive service conditions
-
Minor elements (P, S, Si, Mn, N) are controlled to low maximum levels to optimize corrosion resistance and weldability.
Robust Construction & VersatilityThese SS flanges are crafted to the highest standards, ensuring robust performance in various industrial settings. Their design supports high-pressure applications, and the galvanizing process protects against corrosion, making them ideal for long-term use. Customizable dimensions allow for seamless integration into any piping system, while ANSI standard compliance guarantees compatibility.
Superior Material & FinishManufactured from grade A105 stainless steel, these flanges boast superior strength and longevity. The silver finish and galvanized surface not only enhance appearance but also provide exceptional resistance to wear, making them suitable for harsh environments in industries such as oil, gas, and manufacturing.
