High Carbon Chromium Bearing Steel (GB/T3086-1982)
High Carbon Chromium Bearing Steel (HCCB) is a type of steel that is specially formulated to resist wear and tear and to provide durability and strength in extreme conditions. HCCB is primarily used in the manufacturing of high-performance bearings, which are designed to withstand extremely high loads and to provide smooth, fast and consistent performance. This makes HCCB ideal for use in a variety of industries, including industrial, automotive and aerospace applications.
The material is available in two distinct grades, HCCB and H+ grades. HCCB is a higher grade and is required for applications that demand greater strength, durability and performance; while H+ is the lower grade and is commonly used in low-load applications where cost is a major factor. Both grades are well-suited for use in automotive and industrial bearings.
One of the key advantages of HCCB is its ability to provide excellent mechanical strength, despite its low carbon content. This is due to its extremely high chromium content, which gives it the capability to resist wear, tear and impact. Additionally, high carbon content helps to provide a wide range of mechanical properties for different applications. Specifically, HCCB is more workable than low-carbon steel and much better at forming operations and cutting. As a result, it is commonly used in the manufacturing of high-precision bearings and other components.
Besides its excellent mechanical properties, HCCB also offers exceptional corrosion resistance. Its high chromium content makes it far more resistant to corrosion than other low-carbon bearing steel alloys. This makes it an excellent choice for many of the high-precision applications mentioned above. Its excellent corrosion resistance also contributes to its longer lifespan and greater reliability.
HCCB is generally easier to work with than other types of bearing steels and is highly cost-effective. It provides excellent strength and durability and is available in both plate and bar form. Both of these forms can be cut and formed with conventional metalworking tools, and the bar stock is typically used for producing finished bearings.
In summary, High Carbon Chromium Bearing Steel (HCCB) is a type of bearing steel alloy specifically designed for use in extreme applications. It is characterized by its exceptional strength, durability and corrosion resistance and is ideal for manufacturing high precision bearings. Thanks to its workability, cost-effectiveness and excellent mechanical properties, HCCB is one of the most popular bearing steels available today.
