304 Stainless Steel Shaft

Built for reliability in demanding applications, the 304 stainless steel shaft plays a critical role in power transmission systems for automated equipment. With excellent corrosion resistance and precision machining, it provides a stable and durable foundation for smooth operation.

Manufactured using advanced CNC turning, each shaft is produced to micron-level precision. Every detail is carefully controlled to ensure consistent performance, making it a dependable choice among high-quality stainless steel CNC parts.

We offer flexible customization for stainless steel CNC parts, including imperial, unified (UNC/UNF), metric, trapezoidal, and non-standard threads. Whether for small-batch production or complex assemblies, we can adapt to your requirements. Send us your drawings for a fast and accurate quotation.

Material

304 stainless steel offers an excellent balance of strength, corrosion resistance, and durability.

• Chromium (Cr): 18.00–20.00%

• Nickel (Ni): 8.00–12.00%

• Carbon (C): ≤ 0.08%

• Manganese (Mn): ≤ 2.00%

• Silicon (Si): ≤ 1.00%

• Phosphorus (P): ≤ 0.045%

• Sulfur (S): ≤ 0.030%

• Nitrogen (N): ≤ 0.10%

Key advantages:

• Excellent corrosion resistance for humid, acidic, and alkaline environments

• High strength with minimal deformation, even under high-speed rotation

• Suitable for hygienic applications, including food and medical equipment

• Strong fatigue resistance for extended service life

Manufacturing Process

Each shaft is machined from a single piece, ensuring structural integrity with no joints or weak points.

• Multi-stage inspection, including runout, dimensional tolerance, and surface finish checks

• Strict quality control to ensure consistent results across batches

Factory-direct supply:

• Competitive pricing without intermediaries

• Flexible production for both small and large volumes

• Optimized machining parameters for smoother rotation and improved wear resistance
