304 Precision Ground Bars

304 Peeled Ground Bars Manufacturer in India Stainless Steel 304 Ground Finished Machined Bars Supplier in Mumbai, India

304 Ground Finished Machined Bars refer to bars made from stainless steel grade 304 that have undergone a machining process to achieve precise dimensions and a smooth surface finish. The term “ground finished” indicates that the bars have been mechanically ground to remove imperfections and achieve tight tolerances.

These bars are commonly used in industries requiring high precision and a polished surface, such as machinery, automotive components, and construction. The machining process ensures that the bars meet specific dimensional requirements and exhibit excellent surface quality, making them suitable for various applications.

Ratna Export’s ground bars are known for their exceptional straightness, minimal out-of-roundness, and smooth surface finish. These qualities are crucial for seamless and efficient production processes, especially in high-speed machining operations and precise feeds in automated lathes. Straightness is vital, particularly when working with long bars, ensuring consistent and accurate components.

Moreover, our stainless steel 304 ground bars exhibit minimal internal stresses, reducing the risk of distortion during machining. This makes them highly suitable for manufacturing long shafts, rolling bearings, and ball bushings. With these superior properties, our ground bars are favoured for various applications, guaranteeing smooth production and high-quality finished products.
