ALLOY-31

Increasing Corrosion Resistance to Never-Before-Seen Levels

The ground-breaking alloy ALLOY-31 from Taashvi Special Alloys pushes the envelope in terms of corrosion resistance. Alloy-31 is a nickel-chromium-molybdenum alloy with improved stability that is engineered for harsh conditions. This makes it a great option for industries that face corrosive difficulties. Experts at Taashvi have painstakingly created its special composition, which guarantees optimal performance in harsh chemical conditions such as phosphoric acid, sulfuric acid, and media containing chlorine.

Key Characteristics of ALLOY-31:

01 Resistance to Corrosion: Because of its remarkable resistance to a variety of corrosive environments, ALLOY-31 can be used in situations where other alloys are inadequate.

02 High Temperature Stability: Because of its high chromium concentration, alloy 31 is reliable in harsh circumstances because it maintains its structural integrity even at high temperatures.

03 Excellent Weldability: Taashvi Special Alloys places great emphasis on ease of fabrication. One example of this is alloy-31, which has exceptional weldability, making production processes more efficient.

04 Low Carbon Content: The low carbon percentage of the alloy adds to its lifetime and durability by strengthening its resistance to intergranular corrosion.

05 Versatility in Applications: Because it can withstand a variety of harsh conditions, ALLOY-31 is used in a wide range of sectors, such as petrochemicals, chemical processing, and pharmaceuticals.

06 Durability and economics: Because of its endurance, stability at high temperatures, and resistance to corrosion, ALLOY-31 is a cost-effective option that lowers maintenance expenses and downtime in crucial processes.
