Brief introduction of chromium-nickel-manganese-nitrogen austenitic stainless steel 0Cr18Ni2Mn12N (Nitronic32)

NITRONIC 32 (also known as 0Cr18Ni2Mn12N) is a stainless steel alloy with excellent corrosion resistance and mechanical properties. The alloy is composed of chromium, nickel, manganese, nitrogen, and iron. The addition of nitrogen and the high levels of chromium and manganese make NITRONIC 32 an excellent choice for structural components exposed to high temperatures. This stainless steel alloy is high in nickel content and has excellent fatigue resistance, making it ideal for high cyclic loading applications.

NITRONIC 32 has higher levels of chromium, nickel, and manganese than standard austenitic stainless steels. It also contains nitrogen, which is what helps to increase its resistance to corrosion and wear. It has a design strength of 187 ksi when compared with 150 ksi of most standard austenitic stainless steels. This makes it an excellent choice for high temperature applications, where strength and creep resistance are important.

NITRONIC 32 is commonly used in the oil and gas industry because of its excellent corrosion resistance, including resistance to pitting, crevice corrosion, and stress corrosion cracking. It also has excellent strength and hardness values, which are needed in severe service applications. This alloy is found in the manufacture of oil and gas valves, actuating arms, and flanges, as well as being used as a cladding material on valve stems, seat rings, and springs.

Due to its high chromium content, NITRONIC 32 is also used in a variety of chemical applications. This alloy is resistant to chemicals such as sulfuric acid and ammonia, making it a suitable choice for chemical processing and storage facilities. NITRONIC 32 is also corrosion resistant to seawater, making it a common choice for applications in marine environments such as ship hulls and underwater piping.

NITRONIC 32 can be hardened using a precipitation surface hardening process and is valued for its resistance to wear caused by friction. This material is commonly found in the manufacture of food processing machinery, like depositing heads, which experience a lot of wear due to the exposure of food products. NITRONIC 32 is also used in the manufacture of medical devices such as implantable surgical instruments, as well as in the aerospace industry.

Due to the excellent performance of NITRONIC 32 in extreme environments, this alloy is popular in many industries. Its resistance to corrosion and wear, combined with its strength and hardness, makes it a go-to material for heavy applications. NITRONIC 32 is available in many forms such as wire, plasma cutting, welding wire, and forgings, allowing for easy fabrication in almost any application. With its excellent performance, NITRONIC 32 is a great choice for any application where a hard, corrosion-resistant stainless steel alloy is required.

Nitronic 32 (UNS S20810/SS 2368) 0Cr18Ni2Mn12N (Nitronic 32) is an austenitic stainless steel that offers highly improved performance characteristics over those of the conventional high-manganese austenitic stainless steels. It is well-suited for both static and dynamic parts of critical applications, particularly in a corrosive environment.

Nitronic 32 has a high level of chromium, nitrogen and manganese content and provides superior corrosion resistance to a variety of corrosive environments. It is heat treated in a vacuum to a hardness of 32 Rockwell C and is used for a variety of high strength parts. Nitronic 32 has superior formability and is well-suited for use in systems involving prolonged exposure to corrosive agents such as seawater. The high nitrogen content brings tremendous hardening benefits to the material, and offers greater toughness, higher strength and improved wear resistance when compared to similarly treated conventional austenitic steels.

Nitronic 32 has good workability and machinability. The nitrogen gives the steel increased toughness and increased resistance to abrasion and fatigue. Because it has higher chromium content, it is suitable for static and dynamic parts that require high temperature resistance and good corrosion resistance. Application includes hot water tanks and containers, valves, pumps and bearings, containers, kitchenware and other items.

Nitronic 32 offers good weldability and fabricability, and good finishing properties. The steel can be welded with standard methods and materials and is easy to work with. It also has good heat treatment properties and is suitable for post-weld hardening procedures. Nitronic 32 can be used in as-welded applications without post-weld hardening, which is an advantage over conventional austenitic stainless steels.

Nitronic 32 is a reliable and cost-effective stainless steel with excellent wear and corrosion resistance. Its mechanical properties remain good up to very high temperatures and it is relatively easy to machine and form. Nitronic 32 is used in a variety of industries where its superior performance over conventional stainless steels makes it an ideal choice.
