A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q4: What makes stainless steel stainless?

A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q5: Can stainless steel rust?

A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q: Can steel round bars be used for making shafts?: Steel round bars are capable of being utilized for the production of shafts. Owing to their exceptional strength and durability, steel round bars find widespread use in various industries for the purpose of shaft fabrication. They possess the ability to endure heavy loads, withstand forces that induce bending and twisting, and exhibit remarkable performance in applications where power transmission or rotational movement is required. Moreover, steel round bars offer commendable machinability, enabling effortless shaping and formation into shafts of diverse sizes and dimensions. Furthermore, heat treatment can be employed to augment the strength and hardness of steel round bars, rendering them even more suitable for shafts operating in demanding environments. In conclusion, steel round bars are an immensely popular choice for shaft production due to their inherent properties and unwavering reliability across a multitude of industrial applications.

Q: What are the different international standards for steel round bars?: There are several international standards that define the specifications and requirements for steel round bars. Some of the commonly used standards include: 1. ASTM A36/A36M: This standard covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings. It specifies the chemical composition, mechanical properties, and dimensional tolerances for steel round bars. 2. ASTM A615/A615M: This standard specifies the requirements for deformed and plain carbon-steel bars for concrete reinforcement. It covers bars with sizes ranging from 6 to 60 mm in diameter and provides guidelines for chemical composition, mechanical properties, and bend tests. 3. BS 4449: This British Standard covers steel bars for the reinforcement of concrete. It outlines the requirements for carbon steel bars in various grades, including B500B and B500C. It specifies the tensile properties, chemical composition, and dimensional tolerances for these steel round bars. 4. DIN 17100: This German standard specifies the general structural steels, including steel round bars. It provides guidelines for the chemical composition, mechanical properties, and technical delivery conditions for different grades of steel bars. 5. JIS G3101: This Japanese Industrial Standard covers general structure rolled steel for various applications. It includes steel round bars and defines the chemical composition, mechanical properties, and dimensional tolerances for different grades of steel bars. 6. ISO 6935-2: This International Organization for Standardization standard specifies the requirements for hot-rolled steel bars for the reinforcement of concrete. It provides guidelines for the chemical composition, mechanical properties, and dimensional tolerances of steel round bars used in construction. These are just a few examples of the various international standards that exist for steel round bars. It is important to consult the appropriate standard based on the specific application and requirements to ensure compliance and quality of the steel round bars used.

Q: How do steel round bars perform under static or stationary loads?: Steel round bars perform exceptionally well under static or stationary loads. Due to their high tensile and compressive strength, they can withstand heavy loads without significant deformation or failure. The structural integrity and stability of steel round bars make them a reliable choice for various applications where static or stationary loads are involved.

Q: Can steel round bars be bent?: Yes, steel round bars can be bent. The flexibility of steel allows it to be shaped and manipulated into various forms, including bending round bars into desired angles or curves.

Q: What is the difference between a hot-rolled and a peeled steel round bar?: The production of a hot-rolled steel round bar involves heating a billet or ingot until it reaches a temperature suitable for shaping. The heated steel is then passed through a series of rollers to achieve the desired shape and size. This rolling process results in a bar with a rough surface texture and a slightly rounded edge. In contrast, a peeled steel round bar goes through a different manufacturing process. It is initially hot-rolled to achieve the desired shape and size, similar to the hot-rolled bar. However, after the initial hot rolling, the peeled bar undergoes a mechanical peeling process. This process entails removing the outer layer of the bar to achieve a smooth and shiny surface finish. Additionally, the peeling process contributes to improving the dimensional accuracy and surface quality of the bar. To summarize, the key distinction between a hot-rolled and a peeled steel round bar lies in the surface finish and dimensional accuracy. While a hot-rolled bar possesses a rough surface texture and a slightly rounded edge, a peeled bar exhibits a smooth and shiny surface finish with enhanced dimensional accuracy. The peeling process elevates the overall quality and appearance of the steel round bar, making it more appropriate for applications where aesthetics or precision hold significance.

Q: What are the different types of steel round bar surface treatments for improved hardness?: There are several different types of steel round bar surface treatments that can be used to improve hardness. These treatments are designed to enhance the strength and durability of the steel, making it more resistant to wear and tear. Some of the common surface treatments for improved hardness include: 1. Heat Treatment: This is a widely used method where the steel round bar is heated to a specific temperature and then cooled rapidly to alter its microstructure. This process can increase the hardness of the steel, making it suitable for applications that require high strength and toughness. 2. Nitriding: Nitriding involves exposing the steel round bar to a nitrogen-rich environment at high temperatures. This treatment forms a hard layer of nitrides on the surface of the steel, enhancing its hardness, wear resistance, and fatigue life. 3. Carbonitriding: Similar to nitriding, carbonitriding involves introducing both carbon and nitrogen into the steel round bar's surface. This treatment creates a hard and wear-resistant layer while maintaining a tough core. Carbonitriding is commonly used for applications that require a combination of hardness and toughness. 4. Induction Hardening: In this process, the steel round bar is heated through electromagnetic induction and then rapidly cooled. This treatment selectively hardens the surface of the steel, leaving the core relatively unaffected. Induction hardening is effective in improving the hardness and wear resistance of specific areas, such as gears or shafts. 5. Chroming: Chrome plating is a surface treatment method where a layer of chromium is deposited onto the steel round bar's surface. This treatment provides excellent hardness, corrosion resistance, and wear resistance. Chroming is commonly used for applications exposed to harsh environments or for parts that require a smooth and hard surface. 6. Shot Peening: Shot peening involves bombarding the steel round bar's surface with tiny metal or ceramic particles at high speed. This treatment induces compressive stress, which improves the material's hardness, fatigue strength, and resistance to crack initiation and propagation. It is important to note that the choice of surface treatment for improved hardness depends on the specific requirements of the application, the type of steel used, and the desired mechanical properties. Consulting with a materials engineer or specialist is recommended to determine the most suitable treatment for a particular steel round bar.
