Usage and Applications
These steels are used for ball and roller bearing applications and are comprised of low carbon steels and high carbon through harden able steel.
First the famous 1C-1.5Cr steel from which the majority of bearings are made. Its structure is apparently well-understood and the focus is on purity in order to avoid inclusions which initiate fatigue during rolling contact. Then there is the M50 steel and its variants, from which bearings which serve at slightly higher temperatures in aeroengines are manufactured, based on secondary-hardened marten site.
Tapered roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling ,During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made.

Production Flow of Chinese Standard Round Bar
1. The common processes are preheated forging quenching, dual refinement solution process, cooling quenching and isothermal quenching. We use heat treatment for dual refinement solution process.
2. Material prepare (billet) — heat up — rough rolling — precision rolling — cooling — packing — storage and transportation
Characteristics of Chinese Standard Round Bar
1. The steel in which the main interstitial alloying constituent is carbon in the range of 0.12–2.0%.
2. As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however it becomes less ductile.
3. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.
4. Regardless of the heat treatment, higher carbon content reduces weld ability. In carbon steels, the higher carbon content lowers the melting point.
- Q: What are the different types of connections used with steel round bars?
- There are several types of connections commonly used with steel round bars, depending on the specific application and structural requirements. Some of the different types of connections include: 1. Welded Connections: This is one of the most common types of connections used with steel round bars. Welding involves fusing two or more round bars together using heat and pressure. It provides a strong and durable connection. 2. Mechanical Connections: Mechanical connections involve using bolts, nuts, or other mechanical fasteners to join steel round bars together. These connections are easy to install and can be disassembled if needed. They are commonly used in applications where frequent disassembly or reconfiguration is required. 3. Threaded Connections: In threaded connections, the steel round bars have threads cut into their ends, allowing them to be screwed together using nuts. This type of connection offers good strength and can be easily tightened or loosened. 4. Adhesive Connections: Adhesive connections involve using a high-strength adhesive or epoxy to bond steel round bars together. This type of connection is commonly used in applications where welding or mechanical connections are not feasible or desirable. 5. Interlocking Connections: Interlocking connections involve the use of specially designed couplers or connectors that fit over the ends of steel round bars, creating a secure connection. These connections are often used in construction projects where quick and efficient installation is required. 6. Grouted Connections: Grouted connections involve filling the gaps between steel round bars with a cementitious grout material. This helps to provide additional strength and stability to the connection. Grouted connections are commonly used in applications where high load capacities are required. It is important to choose the appropriate type of connection based on the specific requirements of the project, considering factors such as load capacity, installation ease, disassembly requirements, and structural integrity. Consulting with a structural engineer or a professional in the field is recommended to ensure the correct type of connection is chosen for the steel round bars.
- Q: What is the difference between a polished and a cold drawn steel round bar?
- A polished steel round bar has undergone a process of buffing or grinding to smoothen its surface and improve its aesthetic appearance, while a cold drawn steel round bar is produced by pulling the steel through a die at room temperature, resulting in increased strength and dimensional accuracy.
- Q: How do you calculate the bending stress in a steel round bar?
- In order to determine the bending stress in a steel round bar, one must take into account the applied load and the properties of the bar. The bending stress is a measurement of the internal forces that arise within the bar when it is subjected to an external load that causes it to bend. The bending stress can be calculated using the following formula: σ = (M * c) / I In this equation: - σ denotes the bending stress, measured in units of force per unit area (such as pascals or psi) - M represents the bending moment, which is the result of multiplying the applied load by the distance from the bar's neutral axis to the point of interest. It is typically expressed in units of force multiplied by distance (e.g., N·m or lb·ft). - c signifies the distance from the neutral axis to the outermost fiber of the bar. It is also referred to as the distance to the extreme fiber or the radius of the bar. - I symbolizes the moment of inertia, which portrays the bar's resistance to bending. It is a property that relies on the shape and dimensions of the bar's cross-section. To calculate the moment of inertia for a round bar, the formula is as follows: I = (π * d^4) / 64 In this equation: - I denotes the moment of inertia - π represents a mathematical constant (approximately 3.14159) - d signifies the diameter of the round bar Once the bending stress has been determined using the aforementioned formulas, it can be compared to the yield strength of the steel material to evaluate the safety factor and ascertain whether the bar will experience permanent deformation or failure.
- Q: What is the average cost of steel round bars?
- The cost of steel round bars can change depending on several factors, including size, grade, and market conditions. Normally, steel round bars are priced between $0.50 and $5 per pound. Nevertheless, it is worth mentioning that these prices are only estimates and can vary depending on the specific needs and location of the purchase. Moreover, it is essential to consider additional expenses like transportation, processing, and applicable taxes to determine the total cost. To obtain the most accurate and current information on the average cost of steel round bars in your region, it is advisable to consult local suppliers or conduct market research.
- Q: Can steel round bars be used in the manufacturing of machinery?
