Brief introduction of 0Cr18Ni12Mo2Ti steel grade

1. Introduction

0Cr18Ni12Mo2Ti steel, also known as 18-12-2 steel, is a ferritic stainless steel and austenite steel hybrid material developed in China in the early 1990s. It has excellent corrosion resistance, superior heat resistance, and excellent mechanical properties. This steel grade is often used in the manufacturing of kitchenware, tableware, medical apparatuses, household appliances and food stains.

2. Properties of 0Cr18Ni12Mo2Ti Steel

0Cr18Ni12Mo2Ti steel has excellent corrosion resistance due to its high chromium and molybdenum alloying elements. As compared to 304 steel, 0Cr18Ni12Mo2Ti steel has higher oxidation resistance, better anti-scaling ability, and improved softening point resistance. Furthermore, because of its good corrosion resistance, this steel grade is suitable for use in highly corrosion-prone environments, such as steel structures in coastal areas and shipbuilding.

0Cr18Ni12Mo2Ti steel is also superior in high-temperature properties, which allows it to be used in hot-gas or high-temperature fluid applications. In comparison to 304 steel, 0Cr18Ni12Mo2Ti steel shows a better property in thermal expansion and creep deformation, as well as superior tensile strength and yield point. The titanium addition also improves the weldability of this steel.

3. Heat Treatment and Forming of 0Cr18Ni12Mo2Ti Steel

0Cr18Ni12Mo2Ti steel is usually preheated before forming since it has a high carbon content. Preheating help avoid cracks and reduce the chances of deformations. For bending, the preheating temperature should reach 650℃, while for welding, the preheating temperature should reach 400℃. For cold forming, heated dies should be used to avoid forming delay.

When it comes to heat treatment, this steel is mostly used in an annealed state. In special cases, an austenitic state may be specified. Heat treatment in the annealed state should be done at 1040-1080℃ and cooled in a slightly warmer furnace.

4. Applications

0Cr18Ni12Mo2Ti steel is suitable for manufacturing kitchenware, gas-powered equipment, tableware and medical appliances. Its excellent properties give it an edge for food processing equipment such as sinks, tables and pallets, as well as scientific research equipment that require high temperature up to 1000℃. It is widely used in fast food industry due to its heat resistance, anti-scaling and flexibility. In addition, 0Cr18Ni12Mo2Ti steel is an ideal choice for industrial parts and components, such as bellows and collectors.

5. Conclusion

0Cr18Ni12Mo2Ti steel is a ferritic stainless steel and austenite steel hybrid material developed in China in the early 1990s. It has excellent corrosion resistance, superior heat resistance, and excellent mechanical properties. This steel grade is often used in the manufacturing of kitchenware, tableware, medical apparatuses, household appliances and food stains. Its high chromium and molybdenum alloying elements improves its corrosion resistance and allows it to be used in hot-gas or high-temperature fluid applications. Its seamless processability, heat resistance, and anti-scaling properties makes it an ideal choice for many application.

0Cr18Ni12Mo2Ti is a steel grade developed in 1970s and it has become one of the most successful and widely used stainless steels in the world. It is mainly used in the food processing industry and chemical industry, as well as in some other industries.

0Cr18Ni12Mo2Ti has a strong and good corrosion resistance, even in the harsh environment. Its several features, like strong resistance to corrosion, good strength, excellent weldability and formability, make it a great choice for many applications. It has a high melting point, high temperature strength and low coefficient of thermal expansion, making it a good choice for heat exchangers and other components which have to work in high temperature environment.

0Cr18Ni12Mo2Ti also has a lower carbon content than other stainless steels. With this low carbon content, the weldability and formability of 0Cr18Ni12Mo2Ti can be ensured. Besides, the carbon content enables it to be annealed easily and its good coldworkability provide stronger mechanical property. Therefore, 0Cr18Ni12Mo2Ti is a great choice for applications where part has to be welded, shaped and formed.

In addition, 0Cr18Ni12Mo2Ti is non-magnetic and it is immune to stress-corrosion cracking. Therefore, it is often used in welding of food processing and chemical industry, to prevent the production from pollution by magnetic and non-metallic foreign matters.

In short, 0Cr18Ni12Mo2Ti is an excellent stainless steel for wide years of applications. It has a low carbon content, non-magnetic and a great resistance to corrosion and therefore, is ideal for heat exchangers, welding and food and chemical industry.
