Alloy 20 Valve Manufacturer in India

Speciality Valve is your leading of Alloy 20 Valve Manufacturer in India, serving customers across Andhra Pradesh, Kerala, and Bihar. Our Alloy 20 valves, also known as Carpenter 20 valves, are engineered from a specialized alloy renowned for its exceptional corrosion resistance properties.

What are Alloy 20 valves?

Alloy 20 is specifically designed to withstand harsh corrosive environments, including sulfuric acid, chloride solutions, and various aggressive chemicals. As a result, these valves find widespread applications in industries such as chemical processing, petrochemicals, and more, where exposure to corrosive substances is common.

Our valves are crafted from a nickel-iron-chromium-based alloy with added copper and molybdenum, offering superior resistance to corrosion and mechanical strength. The alloy typically comprises approximately 24% nickel, 20% chromium, 3-4% copper, and 2-3% molybdenum, along with trace amounts of other elements like iron, manganese, and niobium.
