Common Types of Stainless Steel Used in CNC Machining
CNC machining frequently utilizes several types of stainless steel, each suited for specific applications. 304 stainless steel is known for its excellent corrosion resistance, making it ideal for food processing and medical devices.
316 stainless steel offers enhanced resistance to chemicals and marine environments, commonly used in aerospace and marine parts.
17-4 PH stainless steel is a precipitation-hardened alloy, providing high strength and hardness for aerospace components.
430 stainless steel is a cost-effective option with good corrosion resistance, often used in automotive trims and appliances. Each type offers unique properties, helping manufacturers meet the needs of diverse industries.
Surface Treatment Processes for Stainless Steel Parts
Surface treatments enhance the performance, appearance, and durability of stainless steel parts. Passivation is a chemical process that removes contaminants and improves corrosion resistance by forming a protective oxide layer. Electropolishing smooths the surface at a microscopic level, providing a bright, clean finish, ideal for medical and food processing applications. Bead blasting creates a uniform matte finish by propelling fine abrasive materials, commonly used for aesthetic purposes. Powder coating adds a protective layer of paint, increasing corrosion resistance and providing color options.
Anodizing (although rare for stainless steel) can enhance surface hardness and appearance.
Chemical blackening creates a dark finish that improves wear resistance and minimizes reflection.
Brushing offers a satin or hairline finish, popular for decorative applications in consumer goods and architecture.
These surface treatments ensure that stainless steel parts meet both functional and visual requirements across various industries.

How to Evaluate the Quality of Stainless Steel Parts?
Evaluating stainless steel parts begins with ensuring dimensional accuracy. Precise measurements are essential, and parts must meet specified tolerances to ensure they fit seamlessly into assemblies. RALLY’s machining ensures tight tolerances of ±0.01mm for high-precision components.
In addition to dimensions, surface finish and structural integrity are critical. A uniform surface treatment, such as polishing or passivation, improves both the appearance and corrosion resistance of the parts. Structural integrity ensures the part is free from defects like warping, cracks, or other deformations that could compromise its performance.
At RALLY, we employ a comprehensive quality control process. Every part undergoes 100% inspection before shipment, ensuring not only precise dimensions but also proper surface finish and mechanical strength. Our ISO-certified processes guarantee parts meet both functional and aesthetic requirements.
Tolerances and Precision Control in Stainless Steel Machining
In stainless steel CNC machining, advanced equipment and processes, such as multi-axis CNC machines and precision grinding, are used to meet strict dimensional requirements.
The typical tolerances for stainless steel parts depend on the complexity and size of the part but generally range between ±0.005 mm to ±0.02 mm.
For critical applications, such as aerospace or medical components, tolerances as tight as ±0.001 mm may be achieved.
Precision control involves quality checks throughout the machining process, including in-process inspections, coordinate measuring machines (CMM), and final product testing.
By maintaining these stringent standards, manufacturers ensure the performance and reliability of stainless steel components across industries.
