Ready to start your project? Our experts are here to help you select the right stainless steel grade and manufacturing process for optimal performance and value.
Stainless steel is renowned for its durability and corrosion resistance, but these same properties present unique challenges in CNC machining. Its tendency to work-harden, its high toughness, and poor thermal conductivity demand specialized knowledge and tooling to achieve precision results. At Yokan, we have mastered these complexities through advanced technology and deep material expertise, ensuring your stainless steel parts meet the highest standards of quality and accuracy.
We understand the intricacies of machining stainless steel and have developed proven methodologies to address them.
01
CNC Turning of Stainless Steel
During turning, stainless steel’s high strength and low thermal conductivity concentrate extreme heat and stress on the cutting tool, leading to rapid wear and potential work-hardening of the part surface.
Our Solution:
• Advanced Tooling: We use premium, wear-resistant carbide tooling with specialized geometries and coatings to withstand high temperatures and reduce built-up edge.
● Optimized Parameters: Our technicians meticulously calculate cutting speeds, feed rates, and depth of cut to manage heat generation and prevent hardening, ensuring consistent tool life and superior surface integrity.
● High-Pressure Coolant: Effective coolant application is critical. We utilize high-pressure systems to effectively control temperature at the cutting zone, evacuate chips, and protect both the tool and the workpiece.
02
CNC Milling of Stainless Steel
The intermittent nature of milling creates impact forces that can cause vibration, chipping of tool edges, and exacerbate work-hardening, especially during conventional (up) milling.
Our Solution:
• Climb Milling (Down Milling): We preferentially employ climb milling techniques. This allows the tool tooth to engage the material at its maximum thickness and exit cleanly, reducing heat, minimizing work-hardening, and extending tool durability.
● Rigid Machine Platforms: Our heavy-duty Makino and Mazak 5-axis CNC machines provide exceptional stability and dampening, essential for absorbing the vibrations inherent in milling stainless steel.
● Stable Tool Paths: We program tool paths that maintain a constant tool load, avoiding sharp directional changes that can cause shock loading and premature tool failure.
03
CNC Grinding of Stainless Steel
Grinding stainless steel generates significant heat, which can cause thermal damage like surface burning (tempering) and metallurgical changes. The material’s toughness also leads to wheel loading, where metal particles clog the grinding wheel, reducing its effectiveness.
Our Solution:
• Specialized Grinding Wheels: We select wheels with the correct abrasive type, grade, and porosity specifically for stainless steel to minimize loading and dissipate heat effectively.
● Precise Heat Management: Through controlled in-feed rates, wheel speeds, and abundant coolant flow, we manage grinding temperatures to prevent surface damage and maintain part dimensional stability.
● Pre and Post-Process Inspection: We rigorously check parts for any signs of thermal distortion or surface anomalies, ensuring the final product meets exact specifications.
Leveraging our specialized techniques and state-of-the-art equipment, we transform even the toughest stainless steel alloys into high-precision components.

Engineer
Navigating custom part manufacturing is crucial to your project’s success. We provide product developers and engineers with precision-machined parts in certified, engineering-grade materials, suitable for both prototyping and full-scale production.
CNC machining is a superior manufacturing method for producing high-quality metal parts. Key benefits include:
● High Precision & Repeatability: Create identical, complex parts with tolerances as tight as ±0.005 mm.
● Consistent Quality: Computer-controlled processes eliminate human error, ensuring every part meets exact specifications.
● Cost-Effectiveness: Reduces labor costs and material waste, especially for medium to high-volume production.
● Material Versatility: Capable of machining a wide range of materials, including all grades of stainless steel.
The final cost depends on several factors, including:
● Part Complexity & Size
● Stainless Steel Grade selected
● Production Volume
● Required Tolerances & Surface Finishes
Despite these variables, Yokan Machining offers significant cost advantages—typically 20-30% lower than Western suppliers—thanks to our experienced engineers, efficient processes, and strong supplier relationships.
Yes, absolutely. Stainless steel machining is one of our core specialties. We provide superior CNC machining services with a focus on unbeatable quality and competitive pricing. Our advanced Makino and Mazak CNC machines are specifically chosen to handle the challenges of stainless steel, preventing issues like tool chatter and ensuring precision surfaces on every order.
For excellent machinability, Stainless Steel 303 is often the best choice. However, the “best” grade depends entirely on the part’s application. Austenitic stainless steels like 304 and 316 are popular for their excellent combination of corrosion resistance, strength, and weldability.
Stainless Steel 304 is generally easier and faster to machine than 316. It offers excellent all-around properties and is the most widely used stainless steel grade. Choose 316 when superior corrosion resistance, particularly against chlorides and salts, is required.
The key difference is the addition of Molybdenum in SS 316.
● SS 304: Excellent general-purpose corrosion resistance. Ideal for most environments.
● SS 316: Contains molybdenum, which significantly enhances resistance to corrosion from chlorides, acids, and saltwater. This makes it the “marine-grade” choice for harsh conditions.
The difference lies in the carbon content.
● SS 304: Max carbon content of 0.07%.
● SS 304L: A “low-carbon” version with a max carbon content of 0.030%.
The lower carbon content in 304L minimizes the risk of carbide precipitation during welding, making it the preferred choice for welded components to ensure optimal corrosion resistance in the heat-affected zones.
Our complete CNC services ensure high quality, competitive prices, and on-time delivery from prototype to production.
