FAQ:
Q1: Why buy Materials & Equipment from OKorder.com?
A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.
Q2: How do we guarantee the quality of our products?
A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.
Q3: What makes stainless steel stainless?
A3: 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.
Q4: Can stainless steel rust?
A4: 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 flat bars be welded?
- Certainly, it is possible to weld steel flat bars. Welding serves as a prevalent and extensively employed technique for connecting or restoring steel materials, which encompasses flat bars. The procedure entails heating the steel until it reaches its melting point and subsequently melding the two sections with the aid of a welding electrode or filler material. The resultant weld forms a robust and long-lasting bond, rendering it suitable for an array of applications within the construction, manufacturing, and other industries where steel flat bars are frequently utilized. Nonetheless, adherence to appropriate welding protocols and methodologies is crucial to guarantee a prosperous weld that possesses structural integrity.
- Q:What does QB stand for in Q235B flat steel? What's the difference between Q235B and Q235A?
- There are also some subtle differences between Q235A and Q235B:1, chemical composition: Q235A:C:0.14~0.22:Mn:0.30~0.65; S:0.050;2, mechanical properties: tensile test without distinction, impact test A do not do, Q235B I-beam, Q235B angle steel, Q235B channel steel, Q235BH steel, Q235B flat steel B do 20 degree impact test, V type impact power (longitudinal) J no less than 27.
- Q:What is the typical width tolerance for steel flat bars?
- The typical width tolerance for steel flat bars can vary depending on the specific grade and manufacturing process, but it is generally within a range of +/- 0.005 to 0.03 inches.
- Q:Are steel flat bars suitable for making gears or sprockets?
- Yes, steel flat bars are suitable for making gears or sprockets. Steel flat bars are commonly used in gear and sprocket manufacturing due to their durability, strength, and ability to withstand high loads and torque.
- Q:How do I store steel flat bars to prevent damage?
- To prevent damage to steel flat bars, it is recommended to store them in a dry and well-ventilated area, away from moisture and direct exposure to elements. You can stack them horizontally on a flat surface, ensuring they are properly supported and not overloaded. Using protective coverings, such as plastic or cardboard, between each layer can also help prevent scratches and other surface damage. Additionally, keeping them away from any corrosive materials and maintaining a consistent temperature can further protect the steel flat bars from damage.
- Q:How strong are steel flat bars?
- Steel flat bars are known for their strength and durability. The strength of steel flat bars can vary depending on the grade and composition of the steel used. Steel flat bars are commonly made from mild steel, which has a relatively low carbon content, making it more ductile and easier to work with. Mild steel flat bars have a moderate strength and are suitable for various applications such as construction, manufacturing, and fabrication. On the other hand, high-strength steel flat bars, such as those made from alloy steels or heat-treated steels, have significantly higher strength properties. These types of steel flat bars are specifically designed to withstand heavy loads, resist deformation, and provide structural support in demanding applications. They are commonly used in industries such as construction, automotive, and aerospace. Overall, steel flat bars are generally considered to be strong and capable of withstanding substantial amounts of force and weight. However, it is important to choose the appropriate grade and size of steel flat bar for the intended application to ensure optimal strength and performance. Consulting with a structural engineer or steel supplier can help determine the most suitable type of steel flat bar for a particular project.
- Q:What are the common standards or specifications for steel flat bars?
- The common standards or specifications for steel flat bars include ASTM A36, ASTM A529-50, and ASTM A572-50. These standards define the chemical composition, mechanical properties, and dimensional tolerances of steel flat bars, ensuring their quality and compatibility with various applications.
- Q:Are steel flat bars used in the manufacturing of appliances?
- Yes, steel flat bars are commonly used in the manufacturing of appliances. Steel is a durable and strong material that offers excellent structural integrity, making it ideal for appliances that require stability and support. Steel flat bars are often used in the construction of appliance frames, brackets, and structural components. They provide a solid foundation for various appliance parts and help ensure the longevity and reliability of the finished product. Additionally, steel flat bars can be easily shaped and welded, allowing manufacturers to create customized designs and configurations to suit specific appliance requirements.
- Q:How do steel flat bars contribute to the overall aesthetics of a project?
- Steel flat bars can contribute to the overall aesthetics of a project by adding a sleek and modern touch. Their clean lines and smooth surfaces create a visually appealing look that enhances the overall design. Additionally, steel flat bars can be versatile in terms of finishes and colors, allowing for customization and coordination with other elements in the project.
- Q:Can steel flat bars be used in fire-resistant structures?
- Yes, steel flat bars can be used in fire-resistant structures. Steel is inherently a fire-resistant material due to its high melting point and low thermal conductivity. In addition to that, steel flat bars are often used in construction for their strength, durability, and versatility. They can be incorporated into fire-resistant structures such as fire-resistant walls, doors, and frames. Steel flat bars can also be used as structural supports and reinforcements in fire-resistant buildings. However, it is important to note that fire-resistant structures require careful design and construction, including the use of appropriate fire-resistant coatings or insulation materials to enhance the overall fire resistance of the building.
