Why Choose Huacheng Hardware for CNC Machining Of Stainless Steel

Extensive processing experience

We have extensive production experience in addressing the challenges of high cutting resistance and rapid tool wear in stainless steel machining, ensuring high precision and reliability in CNC machining of stainless steel parts.

Comprehensive quality control

To address dimensional tolerance deviations in the mass production of stainless steel CNC parts, we implement a “self-inspection, mutual inspection, and specialized inspection” process. Detailed dimensional inspection reports and Material Test Reports (MTR) are provided for every batch of parts, ensuring 100% quality control prior to shipment.

Flexible production scheduling

We can rapidly adjust production priorities for different orders to accommodate urgent requests or last-minute additions from overseas clients, cutting the delivery lead time for custom parts by more than 30% compared to the standard 15–20 days.

Core Capability Parameters for CNC Stainless Steel Machining

Surface roughness: Typically Ra ≤ 1.6 μm for standard milling; Ra ≤ 0.08 μm achievable for high-gloss finishing.
Tolerances: ±0.01 to ±0.05 mm; the ISO 2768-mk international standard applies to any dimensions without specified tolerances.
cnc milling stainless maximum workpiece capacity is 1000mm×500mm×600mm
The standard maximum machining length for CNC stainless steel lathes is 300mm~1500mm
‌We can provide DFMA optimization recommendations to help you reduce manufacturing costs without compromising performance.
We offer end-to-end visual order tracking, including photo and video documentation for every production stage, and provide a comprehensive inspection report prior to shipment.
We offer a wide range of surface treatment services, including mirror polishing (Ra 0.02μm), brushing, sandblasting, electropolishing, and passivation.

Materials Guides for CNC Machining Stainless Steel

Material grade	Material Core Performance	Characteristics of CNC Machining
304（0Cr18Ni9	General-purpose austenitic stainless steel; resistant to neutral corrosion; tensile strength of approximately 520 MPa.	The cutting speed is controlled at 100–150 m/min; the material exhibits a moderate tendency for work hardening, and tool wear is controllable.
316L（00Cr17Ni14Mo2)	Low-carbon, molybdenum-bearing austenitic stainless steel with exceptional resistance to acids, alkalis, and marine corrosion.	Due to the higher toughness, the coolant flow rate must be increased during cutting to prevent the material from sticking to the tool, which would result in surface roughness exceeding specifications.
303	Free-machining austenitic stainless steel with added sulfur to improve machinability.	Chip evacuation is smooth, machining efficiency is 20% higher than that of 304, and high-speed turning is achievable.
440C	Martensitic stainless steel; high hardness (HRC 55 or above) and excellent wear resistance.	For finish machining after quenching, it is necessary to control thermal deformation to avoid dimensional deviations.
