GB/T. 4237 2205 Tubo in acciaio inossidabile – Product Overview

IL GB/T. 4237 2205 Tubo in acciaio inossidabile is made from 2205 duplex stainless steel, a high-performance alloy that combines the benefits of both austenitic E ferritic stainless steels. Known for its exceptional strength, resistance to corrosion, and ability to withstand high pressures, this stainless steel pipe is widely used in demanding applications, particularly in industries such as chemical processing, petrochemical, marine, e costruzione.

2205 duplex stainless steel features a unique microstructure that provides a superior balance of properties, including higher strength compared to 304 O 316 stainless steels, while maintaining excellent resistance to stress corrosion cracking (SCC), pitting, and crevice corrosion. This makes it an ideal choice for applications that require both high strength and excellent corrosion resistance.

Unique Features of GB/T 4237 2205 Tubo in acciaio inossidabile

• Exceptional Corrosion Resistance: IL 2205 duplex stainless steel offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in chloride-rich environments such as seawater.
• Alta resistenza: IL 2205 duplex alloy provides up to twice the yield strength of standard austenitic stainless steels (such as 304 O 316), making it a great choice for high-pressure applications.
• Excellent Weldability: Despite its high strength, 2205 acciaio inossidabile offers excellent weldability with standard welding methods, ensuring easy fabrication without compromising its mechanical properties.
• Resistance to Fatigue and Thermal Cycling: The duplex structure gives 2205 acciaio inossidabile a higher resistance to fatigue and thermal cycling, making it ideal for dynamic applications where stress and temperature fluctuations occur frequently.
• Conveniente: The high strength-to-weight ratio of 2205 makes it a cost-effective material, as thinner-walled pipes can be used compared to austenitic grades without compromising performance.
