Grade and Composition

304 Grade

The 304 grade stainless steel flat bars are composed primarily of chromium (18 - 20%) and nickel (8 - 10.5%). This combination provides excellent corrosion resistance in a wide range of environments, including mild industrial and urban atmospheres. The presence of chromium forms a passive oxide layer on the surface of the steel, protecting it from rust and other forms of corrosion. The nickel content enhances the ductility and toughness of the material, making it suitable for applications where formability is crucial.

316 Grade

Our 316 grade flat bars offer even greater corrosion resistance, especially in chloride - rich environments such as coastal areas and chemical processing plants. In addition to the chromium and nickel found in 304 grade, 316 grade contains molybdenum (2 - 3%). Molybdenum significantly improves the pitting and crevice corrosion resistance of the steel, making it ideal for applications exposed to harsh chemicals or saltwater.

Dimensions and Precision

Thickness

We offer these flat bars in thicknesses of 3mm and 4mm, providing flexibility for different applications. The precise thickness ensures consistent performance and compatibility with various manufacturing processes. Whether you are using them for structural support or decorative purposes, the accurate dimensions guarantee a perfect fit.

Rectangular Shape

The rectangular shape of these flat bars is cold - drawn, which results in a smooth surface finish and tight dimensional tolerances. Cold drawing is a process that involves pulling the steel through a die at room temperature, which not only improves the surface quality but also enhances the mechanical properties of the material. The rectangular cross - section provides a larger surface area compared to round bars, making them suitable for applications where a flat surface is required, such as in construction, machinery, and automotive industries.

Mechanical Properties

Strength

Both 304 and 316 grade stainless steel flat bars exhibit high tensile strength. The cold - drawing process further enhances their strength, allowing them to withstand heavy loads and stresses. This makes them suitable for use in structural applications where reliability and durability are essential.

Ductility

These flat bars are highly ductile, which means they can be easily formed, bent, and welded without cracking. This property is particularly important in manufacturing processes where the steel needs to be shaped into different forms to meet specific design requirements.

Surface Finish

The cold - drawn process gives our flat bars a smooth and uniform surface finish. This not only enhances the aesthetic appeal of the bars but also reduces the risk of corrosion by minimizing the surface area available for contaminants to adhere to. The smooth surface also makes the bars easier to clean and maintain, which is crucial in applications where hygiene is a concern, such as in the food and beverage industry.

Applications

Construction

In the construction industry, these flat bars can be used for structural support, framing, and decorative elements. Their corrosion resistance and high strength make them suitable for both indoor and outdoor applications, ensuring long - term durability in buildings and infrastructure projects.

Machinery

In machinery manufacturing, the flat bars are used for components such as shafts, brackets, and guides. Their precise dimensions and excellent mechanical properties contribute to the smooth operation and reliability of machinery.

Automotive

The automotive industry benefits from the use of these flat bars in various parts, including chassis components, engine mounts, and decorative trims. The corrosion resistance and formability of the stainless steel make it an ideal material for automotive applications, where both performance and aesthetics are important.

Food and Beverage

Due to their corrosion resistance and smooth surface finish, 304 and 316 grade flat bars are widely used in the food and beverage industry. They can be used for equipment such as conveyor belts, storage tanks, and processing machinery, where hygiene and resistance to food - related corrosion are critical.

Chemical Processing

In chemical processing plants, the 316 grade flat bars are essential for equipment exposed to harsh chemicals. Their high resistance to corrosion and pitting ensures the safe and efficient operation of chemical processing equipment.

In conclusion, our cold - drawn rectangular 304 and 316 grade stainless steel flat bars offer a combination of high - quality materials, precise dimensions, excellent mechanical properties, and a wide range of applications. Whether you are in the construction, machinery, automotive, food and beverage, or chemical processing industry, these flat bars are a reliable choice for your projects.
