China Hot Rolled Black Polished Duplex Alloy Stainless Steel Round Bar
Introduction
Our China Hot Rolled Black Polished Duplex Alloy Stainless Steel Round Bars are a premium choice for various industrial and construction applications. These bars are crafted with precision and adhere to international standards such as ASTM 201, 304, 316, 2205, and 310S, ensuring high - quality performance and reliability.
Product Features1. Surface Treatment
The surface of these stainless steel round bars undergoes a bright treatment. This not only gives the bars an aesthetically pleasing appearance but also provides several functional benefits. The bright finish reduces the surface roughness, which in turn minimizes the adhesion of dirt, dust, and other contaminants. It also enhances the corrosion resistance of the bars, as a smooth surface is less likely to trap moisture and other corrosive agents. Moreover, the bright finish makes the bars easier to clean and maintain, which is crucial for applications where hygiene is a concern.
2. Shape
The bars are round in shape. The round shape offers several advantages over other shapes. It provides uniform strength in all directions, making it suitable for applications where the bar may be subjected to forces from multiple angles. The round cross - section also allows for easy handling and installation. For example, it can be easily inserted into circular holes or used in rotating machinery without the need for complex alignment. Additionally, the round shape is more aerodynamic, which can be beneficial in applications where fluid flow or air movement around the bar is a factor.
3. Material Composition
We offer a range of duplex alloy stainless steel grades, including ASTM 201, 304, 316, 2205, and 310S. Each grade has its own unique chemical composition and properties.
ASTM 201: It is a cost - effective option with good corrosion resistance and strength. It contains a relatively high amount of manganese, which helps to reduce the cost while maintaining decent mechanical properties.
ASTM 304: This is one of the most widely used stainless steel grades. It has excellent corrosion resistance in a variety of environments, including mild chemical and atmospheric conditions. It is also highly formable and weldable, making it suitable for a wide range of fabrication processes.
ASTM 316: It contains molybdenum, which significantly enhances its corrosion resistance, especially in chloride - rich environments such as coastal areas or chemical processing plants.
ASTM 2205: This duplex stainless steel grade combines the advantages of austenitic and ferritic stainless steels. It has high strength, good corrosion resistance, and excellent resistance to stress - corrosion cracking.
ASTM 310S: It is a high - temperature stainless steel grade with excellent oxidation resistance at elevated temperatures. It is commonly used in applications such as furnace components and heat - treating equipment.
4. Manufacturing Process
These bars are hot - rolled, which is a manufacturing process that involves heating the steel above its recrystallization temperature and then rolling it into the desired shape. Hot rolling offers several benefits. It improves the mechanical properties of the steel, such as its strength and ductility. The hot - rolling process also allows for the production of large - sized bars with consistent quality. After hot rolling, the bars are polished to achieve the bright finish, which further enhances their surface quality and performance.
5. Size and Customization
We can provide these stainless steel round bars in a variety of sizes to meet different customer requirements. Whether you need small - diameter bars for precision applications or large - diameter bars for heavy - duty construction, we have the capabilities to fulfill your needs. In addition, we offer customization services. If you have specific requirements regarding the length, diameter, or other dimensions of the bars, our technical team can work with you to develop a customized solution.
