Alloy Steel Rod/Bar
Alloy steel bars refer to a type of alloy steel with a cross-section similar to a round shape. Alloy steel bars are widely used in military industry, automobile, aviation, shipbuilding, railway, nuclear power and other industries. They are also used in the production of fasteners, gears, and other components that require increased strength and durability.
The specific combination of elements used in an alloy steel bar determines its properties, such as increased strength, hardness, and resistance to wear and corrosion.
The main processes of alloy steel rods are: hot-rolled alloy steel rods, cold-rolled alloy steel rods, and cold-drawn alloy steel rods.
The main shapes of alloy steel bars are: alloy steel round bar, alloy steel square bar, alloy steel flat bar, alloy steel hexagonal bar.
Alloy Steel Round Bar is made up of different material grades such as A-182, F5, F9, F11, F12, F22 & F91. These are made up of various metal alloys that are corrosion resistant and strong. Yinggui is a leading supplier and manufacturer of these Alloy Steel Round Bar products.
