8620 Hot Rolled Steel Bar
Alloy Steel Round Bar 8620 Products Description
8620 Round Bar is a low carbon nickel, chromium and molybdenum alloy steel known for its strength, toughness and core strength.
The low carbon content of 8620 alloy bar makes it easy to weld and process, while the shell and soft, ductile core make it wear resistant.
Wide range of uses for 8620 Round Bar:
Used in bushings and sleeves to reduce friction and provide support in sliding and rotating applications;
Ideal for pins and pinions due to the wear resistance of 8620 round bar;
Suitable for shafts in heavy machinery due to the high tensile strength of 8620 solid bar;
Preferred for making ratchets due to the durability of 8620 solid steel bar;
Used to make spindles for fixed or rotating machining and woodworking tools;
Helps in making bearings in industrial machinery and automobiles due to the high load-bearing capacity of 8620 alloy solid bar.
