AI Overview
20Cr2Ni4 steel,
a low alloy carburizing steel
, is often used in bearing applications.
It's known for its high strength, wear resistance, and toughness, making it suitable for parts like gears, shafts, and other components where high load and good toughness are needed.
After carburizing, the surface of 20Cr2Ni4 steel develops high hardness, wear resistance, and contact fatigue strength, while the core retains good toughness.
Key properties and characteristics of 20Cr2Ni4 bearing steel:
-
High Strength and Toughness:
The steel is designed to withstand significant loads and impacts.
-
Excellent Wear Resistance:
The carburized surface provides exceptional resistance to wear and abrasion.
-
Good Contact Fatigue Strength:
The steel can withstand the stresses of rolling contact fatigue.
-
High Hardness:
The surface achieves a high hardness level after carburizing.
-
Medium Weldability:
While not ideal for welding, the steel can be welded with specific methods and filler metals.
-
Susceptibility to Temper Brittleness:
The steel can be prone to temper brittleness, which is a reduction in toughness after heat treatment.
-
Sensitivity to White Spots:
There's a risk of white spots (micro-cracks) forming in the steel, which can reduce its durability.
Applications:
-
Carburized Parts:Gears, shafts, and other components where a hard, wear-resistant surface is needed, while the core retains toughness.
-
Bearings:Particularly in applications requiring high load capacity and good toughness.
-
Large Cross-Section Parts:The steel is suitable for components where a significant section needs to be hardened.

G20Cr2Ni4 bearing steel is
a commonly used high-quality alloy
carburized
bearbing steel
. After carburizing, the surface has high performance on hardness, wear resistance and contact fatigue strength. At the same time, the heart retains good toughness and can withstand high impact loads.
carburized
Carburizing, or carburising, is
a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide
. The intent is to make the metal harder and more wear resistant.
