Low Alloy Duplex Stainless Steel 1Cr21Ni5Ti
Low alloy duplex stainless steel 1 Cr21Ni5 Ti (UNS S32101/S32109) is an austenitic-ferritic stainless steel combining high yield strength, corrosion resistance, and very good local formability with its austenitic content. It has excellent oxidation resistance and good weldability. 1 Cr21Ni5 Ti duplex stainless steel is widely used in a variety of high temperature and corrosive environments for a variety of structural applications.
Low alloy duplex stainless steel 1 Cr21Ni5 Ti exhibits excellent ductility when cold worked and forged. It can easily be formed into various shapes such as rectangular hollow sections, circles, ellipses, squares, angles, and channels. It can be drawn to desired size and profile. Its exceptional formability enables it to be bent and rolled into desired shapes. It also demonstrates excellent weldability when welding with stainless steel electrodes. Its resistance to corrosion and wear is remarkably better than that of carbon steel. It also exhibits good mechanical properties, making it suitable for fabrication in various industries.
Compared to austenitic stainless steel types, 1 Cr21Ni5 Ti has a higher inter-metallic strength and improved corrosion and thermal cycling resistance. Its high yield strength and hardenability enable it to be too hard to be machined. Therefore, it should be machined using conventional methods like grinding and sawing and heat treatment should be adapted before and after machining.
Low alloy duplex stainless steel 1 Cr21Ni5Ti has a corrosion fatigue strength that is much higher compared to that of austenitic stainless steels. It resists stress corrosion cracking, pitting and crevice corrosion, preventing failure from occurring even in severe mechanical loading conditions. It can be used in a wide temperature range from -200°C to +400°C without compromising its properties.
Durability and Strength of 1 Cr21Ni5 Ti duplex stainless steel are among its best features. It also possesses great fatigue strength and can withstand cyclical loading conditions better than other materials. It can survive higher stresses than pure austenite or ferrite and is durable in extreme conditions. Its ability to resist stress corrosion cracking, pitting and crevice corrosion ensures that it can be used in a variety of applications such as pumps, valves and pipelines handling corrosive media including oil, gas, water and chemicals. Its excellent resistance to thermal cycling offers added protection in harsh environments where temperatures frequently change.
Low alloy duplex stainless steel 1Cr21Ni5Ti offers excellent properties that make it suitable for use in a variety of applications. Its excellent formability, hardness, corrosion resistance, strength and durability make it an ideal solution for a wide range of industries including oil and gas, chemical processing and food processing.
