Expertise

CNC Milling Stainless Steel & Steel

Stainless steel and steel place high demands on machining: Low cutting speeds, high cutting forces and heat generation require stable machines, optimal tool selection and well-designed cooling strategies. Our 5-axis machining enables complex geometries in a single setup.

On our DMG Mori Ecomill 70 (travel 700 × 560 × 510 mm) we manufacture milled parts from all common stainless steel and steel grades. The 5-axis capability allows undercuts, angled bores and freeform surfaces without re-clamping.

Stainless Steel & Steel Grades for Milled Parts

From corrosion-resistant V4A to high-strength tool steel — we mill the right material for your application.

V4A

1.4404 / V4A (AISI 316L)

Molybdenum-bearing stainless steel with enhanced corrosion resistance. For chemical, pharmaceutical, food and medical applications.

V2A

1.4301 / V2A (AISI 304)

The standard stainless steel: Good corrosion resistance, good weldability. For general applications and mechanical engineering.

42CrMo4

42CrMo4 (1.7225)

Quenched and tempered steel with high strength (1,100 MPa). For highly stressed machine parts, gears and shafts.

S355

S355J2 (1.0577)

Structural steel with good weldability (355 MPa). Economical for brackets, consoles and fixtures.

C45

C45E (1.1191)

Case hardening and quenched/tempered steel for shafts, axles and mechanically stressed parts. Good machinability.

1.2379

1.2379 (X155CrVMo12-1)

Cold work / tool steel with very high wear resistance (62 HRC). For stamping and cutting tools.

Benefits

Benefits of Our Steel Milling Capability

01

5-Axis Machining

Complex geometries, undercuts and angled bores in a single setup. Fewer re-clampings = higher precision.

02

Corrosion Resistance

V4A milled parts for chemical, pharmaceutical and food industries. Passivation and electropolishing available as post-treatment.

03

High Strength

Quenched and tempered steels like 42CrMo4 (up to 1,100 MPa) for highly stressed components. Heat treatment before or after milling.

04

Small Series & Single Parts

Economical production from 1 piece. Optimized NC programs reduce unit costs even for small batch sizes.

05

Drawing or 3D Model

STEP, DXF, PDF — we process all common formats. CAM programming directly from your 3D model.

06

Surface Treatment

Burnishing, zinc plating, nickel plating, passivation or electropolishing — through certified partners.

Tolerances

Precision for Steel Milled Parts

Dimensional Tolerances from IT7

Fits H7/g6 also for hardened steels. IT6 with grinding or rework possible.

Surfaces to Ra 0.8

Stainless steel and steel typically deliver Ra 0.8–1.6 after milling. Ra 0.4 achievable with finishing cuts.

Flatness & Parallelism

Through thermally stable machining and stress relief annealing we minimize distortion for large milled parts.

Threads & Precision Bores

Metric threads, Helicoil inserts (recommended for stainless steel) and precision bores H7 in all steel grades.

FAQ

Questions about Milled Parts from Stainless Steel & Steel

Q1Which stainless steel grades do you mill?

V4A (1.4404), V2A (1.4301), Duplex (1.4462) and more on request. Also austenitic and ferritic grades.

Q2Can you mill hardened steel?

Up to approx. 50 HRC we can machine with solid carbide cutters. For tool steel 1.2379 we recommend: Pre-mill → Harden → Grind functional surfaces.

Q3What is the difference between V2A and V4A?

V2A (1.4301) is the standard stainless steel. V4A (1.4404) additionally contains molybdenum and is significantly more resistant against chlorides and pitting. For chemical and food applications we recommend V4A.

Q4Do you offer heat treatment?

Yes — through certified partners we offer quenching and tempering, case hardening, nitriding and induction hardening. Heat treatment is included in the quotation.

Q5How large can steel milled parts be?

Up to 700 × 560 × 510 mm on our Ecomill 70. For larger parts we use our partner network.

Q6What do stainless steel milled parts cost?

Stainless steel is more expensive to machine than aluminum (lower cutting speeds, higher tool wear). Simple V2A parts from approx. €50–100/piece, complex V4A parts from approx. €150–400.

Q7Can you produce 5-axis milled parts?

Yes — our Ecomill 70 is 5-axis capable. This allows us to manufacture complex geometries with undercuts and angled bores in a single setup.

Q8Do you also manufacture welded assemblies?

Yes — milled individual parts can be TIG-welded into assemblies through our partners. We offer complete assemblies especially for V2A and S355.
