Stainless steel is one of the key materials in our workshop. Valued for its corrosion resistance, hygienic properties, and excellent mechanical strength, it’s ideal for producing precision parts, especially in demanding environments.
Widely used in the automotive, aerospace, hydraulics, food, and pharmaceutical industries, stainless steel delivers high performance without the need for surface treatments. It combines durability, aesthetics, and technical excellence, all while meeting strict hygiene and safety standards.
At Meunidec, we have mastered the custom machining of stainless steel in small and medium series. Thanks to our high-performance machinery and expertise in CNC precision turning, we ensure the compliance of your parts, even for the most demanding applications.
Why choose stainless steel for your machined parts?
Because it guarantees maximum durability, natural corrosion resistance, and mechanical performance suited for many industrial sectors. Stainless steel also allows for clean and brilliant finishes without the need for additional treatment.
We put our expertise at your service to assist you with:
Choosing the right grade for your environment
Defining your tolerances and surface finishes
The rapid and reliable production of your functional parts
✔ Advantages :
⚠ Limitation :
Demanding machining: The material’s hardness can increase cycle times and wear down tools.
Higher material cost: More expensive than conventional steel, which should be factored into your cost/performance analysis.
Critical grade selection: The right grade is necessary to ensure specific properties like weldability, resistance, or magnetism, depending on the application.
Most common stainless steel grades used in precision machining
Austenitic stainless steels (304, 316): Non-magnetic, highly corrosion-resistant, and widely used.
Ferritic stainless steels: Magnetic, more economical, and used for moderate stress.
Martensitic stainless steels: Suitable for heat treatment and ideal for parts requiring high mechanical strength.
Typical applications of stainless steel in precision machining
Food & beverage industry: Nozzles, fittings, and parts that come into contact with fluids or food.
Chemical & pharmaceutical industries: Laboratory equipment and surgical instruments.
Automotive: Engine parts, pollution control systems, and durable supports.
Aerospace: Fasteners and structural parts exposed to humidity or chemical agents.
Hydraulics: Bushings, inserts, and components resistant to water and pressure.
Energy & ecological transition: Durable components for severe environments.
