304L, 316L and austenitic grades: stainless parts for food, pharma, marine and industry. CNC milling and turning, online quote.

Stainless steel

Machined stainless: corrosion resistance and shop requirements

Machined stainless steel suits wet, aggressive or hygiene-sensitive environments. 304L and 316L cover most industrial specifications.

CNC machining stainless requires controlled parameters (speed, tooling, coolant) to limit work hardening and hold dimensions.

Lusinage delivers flanges, shafts, fittings, brackets and process parts in stainless with critical feature control and grade advice.

Material benefits

Benefits of stainless in machined parts

Excellent corrosion resistance

Suited to wet, chemical and some food or pharma applications.

Durable mechanical performance

Reliable parts for fastening, transmission and process equipment.

Cleanliness and appearance

Valued for visible equipment and contamination-sensitive areas.

Wide grade range

304L, 316L and others depending on chlorides, temperature and load.

Processes

CNC machining of stainless

CNC milling

Prismatic parts, pockets and holes in stainless steel: dimensional accuracy and finishes suited to industrial integration.

CNC turning

Shafts, bushes, flanges and rotational parts in stainless steel with controlled concentricity for transmission and fastening.

EDM

Internal shapes, cavities and challenging geometries in stainless steel when conventional tooling reaches its limits.

3D printing

Rapid prototyping before CNC machining in stainless steel or form validation; transition to machined series after mechanical sign-off.

Sectors

Industries using machined stainless

Food processing

Washable parts, brackets and interfaces for production lines.

Pharma and laboratories

Technical components, R&D prototypes and clean small batches.

Chemical and process

Flanges, fittings and parts exposed to fluids and agents.

Marine and offshore

Fasteners and mechanisms in salt environments.

Industrial machinery

Transmission, structure and maintenance in harsh environments.

Comparison

Stainless vs steel and aluminium

Material premium offset by durability in corrosive environments — grade confirmed on quote.

Material Strength Machinability Corrosion Material cost Typical uses
Aluminium Good (5xxx / 6xxx / 7xxx alloys) Excellent Good (anodising possible) Moderate Structures, housings, aerospace and automation parts
Steel Very high (C45, 42CrMo4…) Good Low without treatment Moderate to low Transmission, tooling, heavily loaded parts
Stainless steel High (304L, 316L…) Fair (work hardening) Excellent Higher Food, pharma, marine, chemical
Brass Fair Excellent Good Moderate Connectors, fluids, bushes, precision parts
Engineering plastics Grade-dependent Good (adapted speeds) Excellent (chemical) Moderate Guides, insulators, prototypes, short runs

Frequently asked questions

Stainless machining: FAQ

316L resists chlorides and aggressive media better; 304L suits many general industrial uses. Describe the environment on the quote.

It work-hardens if parameters are wrong. Partner shops use CNC strategies suited to austenitics.

Yes, especially 316L for technical parts; per client spec (roughness, contact zones).

Possible per project; state normative or client requirement on the quote.

Standard machined finishes to finer fits on sealing and bearing surfaces — per drawing.

Similar to steel for comparable geometry; grade and stock confirmed on quote.

STEP, dimensioned PDF, explicit stainless grade and quantity.

Measurement from sample possible: modelling then machining after approval.

Stainless for corrosion and pressure; brass for machinability and connectors — we advise by fluid and standard.

Checks per critical dimensions; report possible if specified.
