Duplex & stainless steel CNC machining

Stainless steel and duplex stainless steels are used where strength, corrosion resistance and durability are essential. These materials are commonly specified for components used in marine, chemical, energy, oil and gas, defence, rail, food processing, pharmaceutical and industrial environments.

WEC Machining provides stainless steel CNC machining and duplex CNC machining, including precision milling and turning for customer-specified components. Our team can machine stainless and duplex parts to drawing, supporting projects where reliability, material performance and dimensional accuracy are critical.

Stainless steel offers excellent corrosion resistance and a clean, durable finish. Duplex stainless steels provide higher strength and improved resistance to demanding environments, making them suitable for more challenging applications.

Precision Stainless Steel and Duplex Machining Services

Machining stainless steel and duplex requires careful control. These materials can work harden, generate heat and increase tool wear if not machined correctly. Using the correct tooling, feeds, speeds, coolant strategy and setup is essential for producing accurate, high-quality components.

WEC Machining supports customers requiring CNC stainless steel parts and duplex machined components for demanding applications. We can manufacture parts with accurate profiles, bores, threads, holes, pockets, slots and turned features.

  • Stainless steel CNC milling
  • Stainless steel CNC turning
  • 316 stainless steel machining
  • 304 stainless steel machining
  • Duplex stainless steel machining
  • Super duplex machining
  • Corrosion-resistant machined components
  • High-strength stainless components
  • Stainless steel parts machined to drawing
  • Prototype and batch stainless machining

Our team can review your drawings, material specification and quality requirements before machining to identify the most suitable manufacturing route.

FAQs

Yes. Stainless steel can be CNC machined into accurate components such as shafts, fittings, housings, plates, brackets and complex parts.

303 stainless steel is often easier to machine, while 304 and 316 are widely used for corrosion-resistant components. The best grade depends on the application and environment.

Yes. WEC Machining can machine 316 stainless steel components to customer drawings, subject to geometry, tolerances and specification requirements.

Duplex stainless steel is used where high strength and corrosion resistance are required. It is often specified for marine, offshore, chemical, oil and gas and heavy industrial applications.

Duplex stainless steel is generally more difficult to machine than standard stainless grades because of its strength and work-hardening behaviour. Correct tooling and machining strategy are important.

Yes, subject to grade, component geometry and specification. Send your drawings and material requirements to WEC Machining for review.
