High-Quality 304F Stainless Steel Ground Bar for CNC and Tooling Applications
Product Overview
The 304F Stainless Steel Ground Bar is engineered for high-precision applications where surface finish, corrosion resistance, and excellent machinability are essential. As a sulfur-enhanced version of 304 stainless steel, 304F is designed to provide superior machinability while maintaining the excellent corrosion resistance and durability of standard 304 stainless steel.
These ground bars are ideal for CNC machining, tooling, and precision engineering. The smooth, ground surface minimizes friction during processing, enhances part accuracy, and reduces the need for post-machining finishing operations. Industries including automotive, aerospace, medical, food processing, and chemical manufacturing commonly utilize 304F ground bars for high-performance applications.

FAQ
Q1: How is 304F different from standard 304 stainless steel?
A1: 304F contains additional sulfur, which enhances machinability, allowing faster machining and longer tool life while maintaining corrosion resistance.
Q2: Can 304F ground bars be welded?
A2: Yes, they can be welded. Use compatible filler metals and consider post-weld annealing to minimize stress and maintain corrosion resistance.
Q3: What surface finish is provided on the bars?
A3: The bars are precision ground with a typical surface roughness Ra ≤1.0 µm, suitable for CNC and tooling applications.
Q4: Are 304F bars suitable for food and medical applications?
A4: Yes, 304F stainless steel is biocompatible, corrosion-resistant, and easy to clean, making it suitable for food and medical equipment.
Q5: Can 304F be heat-treated to increase hardness?
A5: No, as an austenitic stainless steel, 304F cannot be hardened by heat treatment but can be annealed to relieve stress or soften for forming.
Conclusion
The 304F Stainless Steel Ground Bar provides a unique combination of high machinability, corrosion resistance, and precision ground finish, making it ideal for CNC machining and tooling applications. Its sulfur-enhanced composition reduces tool wear, improves manufacturing efficiency, and ensures consistent performance. Suitable across industries including automotive, aerospace, medical, food processing, and chemical manufacturing, 304F ground bars offer precision, durability, and reliability for high-performance engineering and manufacturing needs.
