Frequently Asked Questions about 304 Stainless Steel CNC Machined Parts

It is a versatile austenitic alloy known as “18-8” stainless steel. Composed primarily of iron with 18% chromium and 8% nickel, it offers an excellent balance of corrosion resistance, ease of fabrication, and high durability, making it the most widely used grade for industrial parts.

In its annealed state, this material is generally non-magnetic. However, it can become slightly magnetic during CNC machining processes due to the transformation of the microstructure under cold working stress. This minor magnetism does not typically affect the material’s inherent corrosion resistance.

While highly resistant, it can rust under extreme conditions. Exposure to high concentrations of chlorides, saline environments, or harsh industrial chemicals can compromise the protective chromium-oxide layer. Proper passivation and regular maintenance are recommended to prevent surface oxidation in these specific environments.

Yes. We provide complete material traceability for every order. Each shipment includes official mill test reports and Positive Material Identification (PMI) data to verify the exact chemical composition.

Our engineers manage work-hardening by using high-performance carbide tooling and maintaining constant, aggressive feed rates. We optimize cooling systems to dissipate heat quickly and ensure tools stay sharp, preventing the material surface from hardening and ensuring consistent dimensional accuracy for all components.

Typical lead times range from two to four weeks depending on geometry complexity and total volume. We maintain a steady stock of raw material to expedite production.
