Complex stainless forms

Stainless Investment Castings.

Near-net stainless castings for complex shapes, internal passages and corrosion-resistant components, supplied to drawing with secondary machining and documentation.

Flanged valve-body form
Product form: flanged valve-body form. Review material standard and service media.

Define the supplied condition, critical dimensions and acceptance plan in the drawing review. Published process references depend on material, geometry and the agreed order scope.

Geometry, Material and Surface Condition.

Internal and external features

Review passages, changes in section and the interfaces requiring machining.

Specified material

Confirm the casting grade, applicable standard, heat treatment and delivery condition.

Final verification

Agree surface treatment, cleanliness, dimensional records and relevant integrity tests.

Production route, manufacturing responsibility, available documentation and acceptance criteria are confirmed for the particular product and order.

Typical Applications

  • Valves and flow-control parts
  • Pump impellers
  • Food and process equipment
  • Industrial hardware and linkages

Materials & Finishes

  • 304 / 304L
  • 316 / 316L
  • 17-4PH
  • Other stainless grades by drawing review
For Procurement & Engineering

Specify Grade and Functional Surfaces

Send a 2D drawing and 3D model where available, together with annual volume and the requirements below. Our engineering review confirms process feasibility before pricing.

  • Material standard and heat-treatment condition
  • Critical casting and machined tolerances
  • Surface and passivation requirements
  • NDT, pressure or cleanliness acceptance criteria

Feature review

Review passages, bores and contact faces together.

Vane geometry + hub fit

The impeller form combines curved vanes with a finished hub and bore. Review the cast surfaces, machined connection and inspection access as distinct features.

For pump and valve components, specify the stainless grade and service environment with the functional surfaces. Define the requested surface condition and any applicable testing on the drawing or specification.

  • Internal passages and machining datums
  • Surface condition and inspection scope

Frequently Asked Questions

When should investment casting replace machining?

It is strongest when geometry is complex and repeat volume can justify tooling while reducing material waste and machining time.

Can castings be passivated?

Yes. Pickling, passivation and other surface treatments can be included according to the material and final-use specification.
