Stainless Steel Machining

Custom Stainless Steel CNC Machining

While some stainless steel grades are easy to machine, such as 300 and 400 series stainless steel, other grades can pose problems when machining. Miller CNC has the equipment, capabilities and experience necessary to manufacture mission-critical components and parts from 300 series, 400 series, 13-8, 15-5, and 17-4 stainless steel. We can heat-treat components to optimize the physical properties based on the application. We utilize cutting-edge CNC milling equipment, including 5-axis milling, and a wide range of advanced technology software to create custom components based on your specific requirements.

As an industry AS9100 and ISO9001:2015 certified machine shop, we can ensure you will receive the high-performance stainless steel components you want with the mission-critical configurations you need.

Contact a Miller CNC expert or submit an RFQ online and let us start machining stainless steel to your specifications.

Benefits of Machining Stainless Steel

Stainless steels are popular alloys for machining applications due to their increased strength, high levels of corrosion resistance and versatility. Stainless steel has an impressive strength-to-weight ratio and a longer life cycle than brass, nickel and titanium. Stainless steel’s strength can be increased through cold hardening and heat curing processes. Stainless steel holds up to extreme temperatures and corrosion-resistant to withstand exposure to acids, chloride and alkaline solutions, which saves you time on maintenance. Stainless steel is incredibly versatile and can be easily formed, welded and machined to various shapes without weakening.

Stainless Steel Machined Parts For Multiple Industries

As an AS9100D certified manufacturer, Miller CNC has been trusted with government and defense contracts for more than a decade. Throughout our tenure, we have built longstanding relationships with stainless steel mills and distributors to supply durable, mission-critical parts to industries such as:

Stainless Steel 300, 400 & Additional Grades

Each grade of stainless steel offers a unique array of benefits. While some stainless steel grades are easy to machine, such as 300 and 400 series stainless steel, other grades can pose problems when machining. Difficult to machine stainless steel grades include 13-8, 15-5, and 17-4. Through years of stainless steel machining experience, Miller CNC has developed efficient methods for machining most stainless steel grades, even in the hardened/heat-treated conditions.

Stainless steels 304 and 316 are processed for improved machinability and can be machined faster and more cost-effectively than other forms of steel. Stainless steel 303 is non-magnetic and resistant to oxidation. Stainless steel 17-4 is a precipitation-hardened martensitic stainless steel.

While these are just a few of the grade-specific benefits of stainless steel, we recommend consulting with a Miller CNC expert prior to choosing a stainless steel for your next project.
