Standard Dimensions and Tolerances for Stainless Steel Flat Bars

Standard Dimensions and Tolerances for Stainless Steel Flat Bars
Selecting the right stainless steel flat bar is crucial for the success of any project, impacting everything from structural integrity to cost efficiency. Understanding the standard dimensions and tolerances ensures optimal performance and seamless integration into your designs. As a trusted supplier, Ruixiang Steel provides comprehensive guidance and high-quality products to meet your precise requirements.

Standard Dimensions Overview
Stainless steel flat bars are typically defined by their width and thickness, and are available in a range of lengths to suit various applications.

Commonly supplied widths can range from as narrow as 10mm up to 500mm . Another source indicates a wider range, extending up to 900mm in width . For thickness, standard products often cover 2mm to 100mm . A supplier's product listing also shows availability from 3mm to 50mm in thickness .

A typical and widely available length for stainless steel flat bars is 6 meters (approximately 20 feet), with other common lengths including 12 meters .

Understanding Tolerances
Dimensional tolerances are a critical aspect of flat bar specifications, defining the allowable deviation from the nominal dimensions. Adherence to these tolerances, which are often governed by international standards such as ASTM and AISI , is essential for ensuring the material performs as expected in its application.

For example, some manufacturers maintain tight tolerances like +/-0.01mm for their products . Specific tolerance guidelines can vary based on the material and dimensions. To illustrate, one manufacturer's precision standards for stainless steel flat bars (using material SUS304D) specify that for thicknesses of 5mm and 6mm, the tolerance is 0 to -0.18mm .

Key Selection Considerations
When choosing a stainless steel flat bar, consider these factors:

Material Grade: The most common grades include 304, 304L, 316, and 316L , each offering different properties suited for various environments and strength requirements.

Surface Finish: Options such as pickled, black, bright, and polished  are available, which can influence both the appearance and corrosion resistance of the final product.

Application Needs: Always match the dimensional specifications and material grade to your project's structural demands and environmental conditions.
