1.Product Process:
Electric-Furnace
Smelting(EF)→Ladle Furnace(LF)→Vacuum Degassing(VD)→ Argon protected
ingot →Multidirectional Forging → (Concave forging
→)Normalizing+Hydrogen Diffusion Annealing → Ultrasonic Flaw Detection
→Queching+Tempering Prehardened
2.Feature:
Belong
to a kind of high carbon chromium bearing steel which most widely used
with a good performance and less alloy content. High hardenability and
good comprehensive performance.Good machinability after spheroidizing
annealing.High hardness, uniform organization, good wear resistance,
high contact fatigue performance after quenching and tempering.And good
hot working performance.

Application:
| For making all kinds of bearing rings and rolling elements. For example; steel ball roller and ferrule of the internal combustion engine, electric motorcycle, automobile, tractors, machine tools, rolling mill, boring machine, mining machinery, general machinery, high load, and high speed rotating mechanical transmission bearing. Except ball bearing and bearing ring, sometimes also used to make tools, such as punching die, measuring tool. |
Cutting:
A. Steel plates: Cutting by bandsaw machine, milling, heat treatment, etc
B. Round bars: Cutting by bandsaw machine, peeling, grinding and turned, heat treatment, etc
