Duplex Steel Valves are made from a balanced mix of austenitic and ferritic stainless steel, typically containing around 22-25% chromium, 4-7% nickel, and 2-3% molybdenum. They offer high corrosion resistance, especially against stress corrosion cracking and pitting, making them ideal for harsh environments. These valves exhibit excellent strength and durability, are superior to standard stainless steels, and are cost-effective. Their enhanced toughness, weldability, and high-temperature resistance make them versatile for various industrial applications.

Duplex steel valves are made from a balanced austenitic-ferritic stainless steel alloy, typically containing chromium, nickel, molybdenum, and nitrogen. This composition provides high tensile and yield strength, excellent resistance to stress corrosion cracking, and superior protection against pitting and crevice corrosion. Duplex steel valves maintain good toughness, fatigue resistance, and impact strength, performing reliably under high pressure, fluctuating temperatures, and aggressive environments, making them suitable for both subsea and onshore applications.

Duplex steel valves are widely used in industries requiring strength, corrosion resistance, and durability. They are commonly employed in oil and gas pipelines, offshore platforms, and marine structures exposed to seawater and harsh chemicals. In chemical and petrochemical plants, these valves are used for controlling flow in reactors, pipelines, and heat exchangers. Duplex steel valves are also suitable for power generation, desalination, and heavy engineering applications, providing reliable sealing, long service life, and safe operation under demanding operating conditions.
