High-Precision Custom Stainless Steel Machining Services for Demanding Applications

Looking for a reliable manufacturing partner for non-standard, custom stainless steel components? We specialize in precision CNC machining, delivering tailor-made stainless steel parts engineered to meet your exact specifications and tightest tolerances.

From prototypes to full-scale production runs, we combine advanced multi-axis machining technology with deep material expertise to solve the unique challenges of machining stainless steel—such as work hardening, thermal expansion, and chip control.

Materials We Work With

We machine a wide spectrum of stainless steel grades to suit various mechanical, thermal, and anti-corrosion requirements:

Austenitic Stainless Steel (300 Series):
- SS304 / SS304L: Excellent formability and corrosion resistance; ideal for general industrial and commercial components.
- SS316 / SS316L: Superior resistance to chlorides and acids; ideal for marine environments, medical devices, and chemical processing equipment.
Martensitic & Ferritic Stainless Steel (400 Series):
- SS410 / SS416 / SS420: High strength and heat treatability; optimal for shafts, valves, and wear-resistant mechanical parts.
- SS430: Good corrosion resistance and thermal conductivity.
Precipitation-Hardening (PH) & Specialty Alloys:
- 17-4PH (AISI 630): High strength, hardness, and outstanding corrosion resistance for aerospace, oil & gas, and high-load applications.
- Duplex Stainless Steel (2205 / 2507): Exceptional mechanical strength and resistance to stress corrosion cracking.

Machining Capabilities & Manufacturing Processes

Our state-of-the-art facility is equipped to handle complex geometries and tight tolerances down to ±0.005 mm.

Manufacturing Process	Description & Capabilities
Precision CNC Milling	3-axis, 4-axis, and 5-axis milling for complex 3D shapes, housings, brackets, and structural components.
CNC Turning & Swiss Machining	High-precision turning for shafts, bushings, pins, threaded fittings, and micro-components with superior surface finish.
Turn-Mill Compound Machining	Single-setup processing for high-concentricity parts with combined turning, cross-drilling, and off-center milling needs.
Deep Hole Drilling & Tapping	Specialized tooling for deep hole drilling, micro-tapping, and precise thread control (UNC, UNF, Metric, NPT, BSPT).
Wire EDM & Hole Drilling	Precision electrical discharge machining for tight-corner slots, keyways, and ultra-hardened stainless steel components.

Post-Processing & Surface Treatments

To enhance corrosion resistance, wear characteristics, and aesthetic appearance, we provide a complete range of finishing services:

Passivation (ASTM A967 / AMS 2700): Removes free iron from the surface to maximize natural corrosion resistance.
Electropolishing: Creates an ultra-smooth, mirror-like finish while improving cleanability for medical and food-grade components.
Bead Blasting & Satin Finishing: Provides a uniform matte finish and removes minor tool marks.
Heat Treatment: Solution annealing, stress relieving, and precipitation hardening (for 17-4PH).
Laser Marking & Engraving: Custom serialization, part numbers, and company logos.
