30CrMnSi with stable high temperature performance

30CrMnSi steel is a high-quality alloy structural steel that is widely used in many fields because of its high strength, high toughness, good wear resistance and fatigue resistance.

First of all, 30CrMnSi steel is widely used in automobile and aircraft manufacturing. It is often used to manufacture various special wear-resistant parts, such as gears, shafts, clutches, sprockets, grinding wheel shafts, etc. In aircraft manufacturing, this kind of steel is used to manufacture important components such as wing girders, engine mounts, landing gear action tubes, shock absorber tubes, as well as some parts on aeroengines.

Secondly, 30CrMnSi steel is also widely used in machinery, ships, bridges and other engineering fields. It is used to manufacture various high-load and high-speed components, such as piston parts, bushings, bolts, nuts, etc., as well as welded components, such as blades, valve plates, and non-corrosive pipes for high-pressure blower fans.

In addition, 30CrMnSi steel also has important applications in petrochemical, aerospace and other manufacturing field.

The characteristics of 30CrMnSi steel are mainly reflected in the following aspects:

High strength and high toughness: This steel has high yield strength and tensile strength, which can meet the requirements of high load and high-speed operation, while also having good toughness and being able to withstand shock and vibration.
Good weldability and processability: 30CrMnSi steel has good weldability, especially when the thickness is no more than 3mm. After welding, the parts need to be heat treated to ensure stable performance. In addition, its processing deformation is minimal and its fatigue resistance is also quite good.
Excellent corrosion resistance: In a corrosive environment, a dense oxide film will form on the surface of 30CrMnSi steel to resist oxidation and corrosion. This allows it to exhibit good corrosion resistance in various organic and inorganic corrosive media.
Stable high-temperature performance: 30CrMnSi steel can still maintain good strength and stability at high temperatures. After high temperature tempering treatment, its comprehensive performance will be further improved.
