Steel 08Kh18N10T: definition, characteristics, chemical composition, application

Steel grade 08Kh18N10T is classified as a class of alloyed, heat-resistant, and heat-resistant austenitic steels. Being corrosion-resistant, it is supplied as sheet and rolled products. It is also available as forged blanks and calibrated rods.

Decoding the marking of steel grade 08Х18Н10Т

The "08" in the name indicates that the steel contains up to 0.08% of carbon. "X18" refers to the chromium content of eighteen percent. The "H10" designation indicates a nickel content of up to ten percent. The "T" indicates a titanium content of up to one percent.

Characteristics of 08Kh18N10T steel

This steel has many advantages. Let's list the main ones:

1. Excellent corrosion resistance. The steel product can be used in conditions of high humidity and chemically aggressive substances without experiencing any corrosion. This also applies to exposure to certain acids. This is achieved thanks to its well-balanced composition. This grade of steel is resistant to intergranular corrosion.
2. Heat-resistant structure. The alloy is resistant to high temperatures, while maintaining the original properties of steel. However, some properties, particularly hardness and strength, may decrease slightly if the alloy is exposed to temperatures above 800 degrees Celsius.
3. Non-magnetic. Characterized by inertness to the effects of a magnetic field.
4. Density. This indicator affects the weight of a part or structure, being important in the design process and during engineering calculations.
5. Smooth surface. Products made from this type of steel can be easily processed, including polished. Remarkably, this does not detract from the surface's anti-corrosion properties.

Chemical composition of steel 08Х18Н10Т

The chemical composition largely influences the characteristics of this steel. Carbon is the primary element in the alloy, at 0.08%. Chromium is required for enhanced performance properties and is present at 17-19%. The alloy also contains nickel, silicon, molybdenum, and manganese. The former is present in amounts ranging from 9 to 11%, while the others reach 0.9%. Titanium is present at 0.7%, which significantly impacts the properties of this steel.

Application of 08Х18Н10Т steel

This grade of steel is widely used in a wide variety of sectors and industries. Its popularity is due to its durability, ease of processing, and strength.

• Manufacturing of components and parts for the chemical industry
• Manufacturing of seamless stainless steel pipes
• Production of welding electrodes, welding fittings, and spark plugs
