Hot Sale High Strength 40cr Steel Factory Direct Supply - China

40Cr steel is a commonly used high-quality alloy structural steel with the characteristics of high strength, good toughness and hardenability.

The main alloying element of 40Cr steel is chromium (Cr).

It contains 0.37% - 0.45% carbon (C), and the chromium content is generally between 0.80% - 1.10%.

Carbon gives steel higher strength and hardness, while chromium can improve the hardenability of steel, so that the steel can obtain a deeper hardened layer after quenching.

At the same time, chromium can also improve the wear resistance and oxidation resistance of steel.

In addition, 40Cr steel also contains a small amount of silicon (Si) and manganese (Mn).

Silicon can improve the oxidation resistance and corrosion resistance of steel, and manganese can improve the hardenability and strength of steel.

After quenching and tempering treatment (quenching + high temperature tempering), 40Cr steel has very high comprehensive mechanical properties.

Its tensile strength is generally around 800 - 1000MPa, and its yield strength is around 600 - 800MPa.

The hardness of 40Cr steel after quenching and tempering is moderate, usually between 220 - 280HRC (Rockwell hardness).

This hardness level can ensure that the steel parts have good wear resistance without becoming brittle due to too high hardness.

Moreover, the impact toughness of 40Cr steel is also very high, and it can remain intact under certain impact loads, making it suitable for parts that withstand alternating stress.

40Cr steel is an alloy structural steel with excellent performance.

It is widely used in industrial production, and its performance advantages can be fully utilized through reasonable heat treatment processes.
