Products Description

 

09CrCuSb Corrosion and Heat Resistant Alloy Seamless Steel Pipe is a high performance alloy steel tube, our product is mainly composed of 0.09% carbon, 0.7% copper and 0.5% antimony, chromium (about 1.0-1.5%) can enhance its hardenability and strength.

The presence of chromium helps to increase the tensile strength, up to 850 MPa, and the yield strength is about 500 MPa, which enables the tube to withstand great stress without deformation.

 

Products Features

 

Outstanding Durability

Our product contains approximately 9% chromium (Cr), which greatly enhances its resistance to corrosion and oxidation, ensuring long-term stability even in extreme environments.


The inclusion of chromium also improves the high-temperature strength and hardness of the pipe, allowing it to maintain its shape and performance under thermal cycling and mechanical stress without deformation.

 

Exceptional Compression Strength

With around 9% chromium (Cr), this alloy exhibits enhanced structural strength and hardness, giving it superior resistance to compressive forces.


Furthermore, chromium contributes to excellent wear resistance, reducing the likelihood of fatigue or distortion during extended service life.


In addition, the copper (Cu) content below 1% increases the alloy's ductility and toughness, enabling it to absorb and distribute stress efficiently, thereby minimizing the risk of brittle failure under pressure.
