Detailed Product Descriptions:

GCr15 steel is a kind of high carbon chromium bearing steel with less alloy content, good properties and the most widely used. After quenching and tempering, it has higher hardness, uniform structure, good wear resistance and high contact fatigue performance. The steel has moderate cold working plasticity, general cutting performance, poor welding performance, high sensitivity to the formation of white spots and tempering brittleness. It's actually CR15.

GCr15 is one of the most commonly used high chromium bearing steels with high hardenability and high and uniform hardness obtained after heat treatment. Wear resistance is better than GCr9, contact fatigue strength is high, has good dimensional stability and corrosion resistance, cold deformation plasticity medium, cutting general, welding poor, sensitive to white spot formation, has the first type of tempering brittleness. In the manufacture of ball bearings, it is used to impurity class H to class C bearing sleeves with a wall thickness of 12mm and an outer diameter of <250mm, diameter

25. 4-50.8 mm steel ball; Rollers with diameter < 22mm can also be used to withstand large loads. High wear resistance is required. High elastic limit. High contact fatigue

Strength of other mechanical parts and a variety of precision measuring tools, such as cold die. Such as machine tool ball screw, turbojet nozzle nozzle nozzle. The plunger. Valve. Bushing, etc.
