Product Description
Alloy Steel DIN 52100 1.3505 SUJ2 EN31 GCr15 535A99 Forged Steel Round Bar
1: 52100 Steel Introduction
52100 steel is a high standard bearing steel. This steel is known for its high carbon content and moderate chromium additions, giving it excellent hardness and wear resistance. As a result, 52100 steel is widely used in the manufacture of bearings, gears and other mechanical parts that are subjected to high loads, high speeds and long-term wear.

7: 52100 Steel Application
Bearing Manufacturing: Bearings are important components in mechanical equipment, subject to high loads and high speeds.
Gear Processing: Gears are key components in the transmission system, requiring good wear resistance and strength. 52100 steel can meet these requirements, ensuring that gears can still maintain good performance after a long period of use.
Other Mechanical Parts: In addition to bearings and gears, 52100 steel is also widely used in the manufacture of a variety of mechanical parts that need to withstand high loads and abrasion, such as balls, rollers, guides and so on.
8. 52100 Steel Heat Treatment
Preheating and Heating
Preheat 52100 steel to 1,550 to 1,650 degrees Fahrenheit (898.89°C), then heat to approximately 1,832 degrees Fahrenheit (1,000°C).
Quenching
At a temperature of 190°C, quenching is done in oil or water to harden the metal. During quenching, the metal cools rapidly, forming a martensitic microstructure.
Tempering
At a temperature of 150-230°C for 2-4 hours. After quenching, the metal is allowed to cool slowly in a process called annealing, which usually takes several hours to further temper the metal and improve its toughness and ductility.
