Hastelloy flanges are basically used for attaching or joining the various threaded elements in non significant or low-pressure circumstances. These flanges exhibit superior corrosion resistance to the oxidizing or decreasing atmosphere. Furthermore, these also show sturdy resistance to stress corrosion cracking, outstanding mechanical properties in the high-temperature situation. Thus these flanges are more convenient for sulfuric acid and hydrochloric acid conditions. However, these flanges comprise superior thermal stability, strength, and functions for a long period of time.


We facilitate our products in the exclusive range, thickness; customize shape and size according to the requirement or demand made by the customers. Well, our products are highly demanding products in the market as it has great features and attributes that make it an ideal product.
