What is GCr15?

Date: 2023-04-03      Hits:

GCr15 is a high carbon chromium bearing steel, similar to the AISI 52100 and JIS SUJ2 steel grades. It is a standard material in China, and it is also widely used in the manufacture of bearings, ball bearings, and roller bearings, just like 100Cr6.

GCr15 steel has a composition of approximately 1% carbon, 1.5% chromium, and small amounts of other elements, such as manganese, silicon, and phosphorus. It has excellent hardness, wear resistance, and fatigue strength, making it ideal for bearing applications.

In addition to bearing applications, GCr15 steel is also used in the manufacture of other mechanical components that require high strength and wear resistance, such as shafts, gears, and tool holders.

Overall, GCr15 steel is a widely used and well-established material grade in the bearing industry, particularly in China, and it is known for its excellent mechanical properties and durability.
