304F Stainless Steel Ground Rod Corrosion-Resistant and Easy to Machine

Product Overview

The 304F Stainless Steel Ground Rod is a premium-grade material engineered for high-precision machining and applications requiring superior corrosion resistance. As a sulfur-enhanced version of standard 304 stainless steel, 304F combines excellent corrosion resistance with enhanced machinability, making it ideal for precision parts, fasteners, automotive components, and medical instruments.

Ground rods in 304F stainless steel offer a smooth, uniform surface that reduces friction during processing and improves the final component's surface quality. This material is particularly suitable for applications where surface smoothness, dimensional accuracy, and consistent performance are essential.

The 304F ground rod is widely used in industries such as aerospace, automotive, food processing, chemical processing, and medical equipment, where high reliability, strength, and resistance to corrosion are critical. Its machinability also ensures cost-effective manufacturing with reduced tool wear and higher production efficiency.

Technical Specifications

Chemical Composition

The chemical composition of 304F stainless steel provides a balanced combination of machinability, corrosion resistance, and mechanical strength:

The higher sulfur content makes 304F easier to machine than standard 304, while retaining excellent corrosion resistance for a wide range of applications.

Key Features

1. Corrosion Resistance
   304F stainless steel ground rods resist rust, oxidation, and corrosion from water, chemicals, and atmospheric exposure. This makes them suitable for both indoor and outdoor applications, including chemical and food processing environments.

2. High Machinability
   The sulfur-enhanced 304F alloy allows for faster machining speeds, longer tool life, and reduced production costs. It is ideal for turning, milling, drilling, and threading operations.

3. Smooth Ground Surface
   Precision ground to tight tolerances, the rod surface is smooth and uniform. This minimizes post-machining finishing operations and ensures high-quality end products.

4. Non-Magnetic (Annealed)
   In its annealed state, 304F stainless steel is non-magnetic, which is essential for applications in electronics, medical devices, and other fields where magnetic interference must be avoided.

5. High Strength and Durability
   With a tensile strength of 505 MPa and yield strength of 210 MPa, 304F ground rods provide reliable mechanical performance under stress, making them suitable for demanding structural and mechanical applications.

6. Consistency and Precision
   Each rod is manufactured to strict dimensional tolerances, ensuring uniform performance across batches and minimizing variability in machining and assembly processes.
