1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel

 

 

What are the characteristics of 1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel?

 

The 1.2541 35WCrV7 45WCrV7 SKS41 Tool Steel has the following characteristics:

 

Characteristics brought by chemical composition:

High hardness foundation: The moderate carbon content is an important element to ensure the hardness of steel. It provides a high hardness foundation for the steel, enabling it to maintain good shape stability and wear resistance during processing and use, and can withstand greater pressure and friction.

Good heat resistance: The presence of elements such as tungsten and chromium enhances the heat resistance of the steel. This makes the steel still maintain high hardness and strength at high temperatures and is not easy to soften and deform. It is suitable for tools or parts that work under high temperature conditions.

Toughness guarantee: The addition of vanadium helps improve the toughness of the steel. When subjected to impact or vibration, the steel can absorb energy without breaking. This is very important for the service life and reliability of tools, especially in some application scenarios that bear impact loads, such as punches and cutting tools.

Characteristics in terms of mechanical properties:

Relatively high hardness: Usually, the hardness is between 58 - 62 HRC. It belongs to a material with relatively high hardness. This enables it to effectively cut and process other softer materials, and it is not easy to wear and deform during use, maintaining good working accuracy.

Outstanding tensile strength: The tensile strength is about 1500MPa, which means that the steel can withstand greater tensile force without breaking, ensuring the structural strength and stability of the tool during use.

Good toughness and elongation: The elongation is usually between 10% - 15%, showing good toughness. This allows the steel to deform to a certain extent without breaking when subjected to external forces. For some tools or parts that need to bear bending, torsion and other stresses, this is a very important performance index.

Heat treatment characteristics:

Strong heat treatability: This kind of steel can further improve its performance through various heat treatment methods. For example, normalizing treatment can improve hardness and strength, while enhancing heat resistance and wear resistance; quenching treatment can rapidly cool the material to obtain high hardness and strength; tempering treatment can adjust the hardness after quenching to obtain better toughness and ductility.

Good adaptability of heat treatment process: During the heat treatment process, the control of temperature and time is relatively flexible. It can be adjusted according to specific needs and usage scenarios to obtain the best combination of performance.

Processing performance characteristics:

Good processability: It has good processability and can be made into various shapes and sizes of tools or parts through multiple processing methods such as forging, rolling, and cutting. During the processing process, the processing difficulty of the steel is moderate. It is not too hard to process nor is it too soft to affect processing accuracy and surface quality.

Good dimensional stability: The processed steel has good dimensional stability and is not easy to change in size during use, ensuring the accuracy and reliability of tools or parts.

Other characteristics:

General corrosion resistance: It has certain corrosion resistance in ordinary environments. However, in some harsh corrosive environments, additional surface treatment or protective measures may be required to improve its corrosion resistance.

Excellent comprehensive performance: It combines multiple properties such as high hardness, good toughness, heat resistance, and processability, making it a high-quality steel widely used in tool manufacturing, mold manufacturing, mechanical processing and other fields.
