Main characteristics and uses of austenitic stainless steel S30120 1Cr17Ni8

《AISI 30120 1Cr17Ni8 Austenitic Stainless Steel》

AISI 30120 1Cr17Ni8 (UNS S30120) is an austenitic stainless steel grade widely used in industrial applications. It is known for its good corrosion resistance, excellent mechanical properties, and high temperature strength. This grade is also known for its excellent formability and weldability which makes it suitable for components that require good formability and weldability such as kitchen equipment and ducting systems.

AISI 30120 1Cr17Ni8 stainless steel contains chromium and nickel as its main alloy elements. Chromium provides the steel a good corrosion resistance, excellent formability, and good weldability. Nickel also plays an important role in improving the mechanical properties and high temperature strength as well as providing good corrosion resistance.

Additionally, due to its austenitic structure, this stainless steel has an excellent low temperature toughness and high ductility which make it suitable for components that need these properties such as valves and tubing. Its stability at both cryogenic and cryogenic temperatures also make it suitable for cryogenic applications.

AISI 30120 1Cr17Ni8 stainless steel also has several other properties such as good oxidation resistance, good toughness and excellent weldability. The good oxidation resistance makes it suitable for high temperature applications as it can withstand continuous exposure to temperatures up to 1000°F. The good toughness and excellent weldability make it suitable for components used in industrial machinery and pipelines.

This grade of stainless steel is also used for automotive exhaust systems because of its excellent resistance to corrosion, especially against oxidation in the exhaust gases. It is also used in condensers and heat exchangers, thanks to its good thermal conductivity and resistance to high temperatures.

AISI 30120 1Cr17Ni8 stainless steel also has excellent mechanical properties. Its elongation at break of 33% is greater than that of many other austenitic stainless steel grades. It also offers good compressive strength and tensile properties which make it suitable for components that require good mechanical properties.

Overall, AISI 30120 1Cr17Ni8 stainless steel is an excellent grade for industrial applications due to its good corrosion resistance, excellent mechanical properties, and good formability and weldability. It is suitable for many industrial applications including, but not limited to, automotive exhaust systems, condensers, heat exchangers, and kitchen equipment and ducting systems.

Type 301 austenitic stainless steel, also known as S30120, belongs to 1Cr17Ni8 stainless steel. It is a commonly used ultra-low-carbon stainless steel. It is used in low-grade applications such as stamping parts. Its main features are as follows:

1. Good formability: It has good formability, good weldability and workability in annealed state, and is easy to make all kinds of mechanical parts.

2. High corrosion resistance: It has good corrosion resistance in the atmosphere, water and some corrosive medium. However, due to the lack of molybdenum and the higher carbon content, it has poor corrosion resistance to the chloride ion medium.

3. Good toughness: Type 301 stainless steel has good toughness performance, but its yield strength and tensile strength are relatively weak.

4. High temperature resistance: type 301 stainless steel also has good oxidation resistance in the temperature range of 800-1575 ℃.

5. Cost-effective: Type 301 stainless steel has a low cost.

6. Main application: It is mainly used for sealing parts and decorated shining parts, and also can be used for low-grade spring and parts of heat resistant steel. Type 301 stainless steel has a wide range of applications, such as kitchenware, containers, cans, automotive trim, and architectural and consumer products.
