Mechanical processing performance for custom stainless steel parts

Stainless steel has good mechanical processing performance:

  • High Hardness: Stainless steel has high hardness, usually requiring a large cutting force for processing. This also leads to higher requirements for the wear resistance of processing tools during stainless steel processing.

  • Good Chip Formation: Stainless steel has good chip formation, which can produce good chip morphology and facilitate chip discharge.

  • Poor Thermal Cutting Performance: Stainless steel has low thermal conductivity and a high thermal expansion coefficient, making it prone to thermal deformation and work hardening during processing. Therefore, it is necessary to control the processing temperature and speed in stainless steel machining and avoid excessive heat accumulation leading to irreversible deformation.

  • Good Plasticity: Stainless steel has good plasticity and can be subjected to various cold and hot deformation processes such as stretching, compression, and bending.

  • Relatively Difficult in Mechanical Processing: Due to the high hardness and toughness of stainless steel, as well as its good cutting performance, its mechanical processing is relatively difficult. It is necessary to choose appropriate cutting parameters, tools, and coolant conditions to ensure processing quality and tool life.

We machine various customized stainless steel parts and have extensive experience in the machining processes components, such as compressor impellers, disks, blades, diffuser, nozzle ring, precision threaded fittings, non-standard threaded parts and bushings.

Stainless steel part is widely used in various industry and fields. Common stainless steel parts include:

  1. Screws and Nuts: Stainless steel screws and nuts are commonly used in situations requiring corrosion resistance and wear resistance, such as in food processing and chemical equipment.

  2. Connectors: Stainless steel connectors, such as flanges, gaskets, and bolts, are widely used in the construction of durable structures such as bridges and buildings.

  3. Instrument Parts: Stainless steel is used to manufacture parts in the production of precision instruments and equipment, ensuring long-term stability and corrosion resistance.

  4. Food Processing Equipment: Stainless steel is extensively used in the manufacturing of food processing equipment such as knives, mixers, and containers because it does not affect the quality of food and is easy to clean.

  5. Automotive Components: Stainless steel parts are used in automotive manufacturing to enhance the corrosion resistance of components, such as exhaust systems and decorative accessories.

  6. Aerospace Components: Stainless steel is used to manufacture parts in the aerospace field due to its strength and corrosion resistance.

  7. Medical Equipment Parts: Stainless steel is widely used in the manufacture of parts for medical equipment, such as surgical instruments, brackets, and implants, to ensure their safety and durability.

  8. Electronic Device Housing: Due to its corrosion resistance, stainless steel is frequently used to manufacture the housing of electronic devices, providing additional protection.

  9. Vibrators and Sensors: Stainless steel is used to manufacture parts for vibrators and sensors, suitable for environments that require stability and corrosion resistance.

  10. Mechanical Seals: Stainless steel excels in the manufacture of mechanical seals used to ensure the sealing performance of pipes and containers.

We can not only machine stainless steel part by high dimensional accuracy according to drawings or samples but also complete various surface treatments as required.

Stainless steel can be processed by various surface treatments to enhance performance and appearance. Common surface treatment methods include:

  1. Polishing:

    • Improves surface smoothness and aesthetics.
    • Removes surface defects and oxidation layers.

  2. Brushing:

    • Creates a uniform linear texture.
    • Enhances appearance and hides surface imperfections.

  3. Electroplating:

    • Increases corrosion resistance and wear resistance.
    • Adds surface layers of different metals, such as nickel and chromium.

  4. Passivation:

    • Enhances corrosion resistance.
    • Removes surface free iron and other impurities through chemical treatment.

  5. Sandblasting:

    • Cleans and removes surface oxidation layers.
    • Produces a uniform surface texture.

  6. Chemical Treatment:

    • Processes like pickling remove oxidation layers and impurities.
    • Improves surface cleanliness.

  7. Anodizing:

    • Increases corrosion resistance and wear resistance (not commonly used for stainless steel but can achieve similar effects through electrochemical treatment).

  8. Thermal Spraying:

    • Enhances surface wear resistance and oxidation resistance.
    • Suitable for repairing worn parts.

  9. Electropolishing:

    • Removes surface material through an electrochemical process.
    • Improves surface smoothness and corrosion resistance.

  10. Coating:

    • Applies organic or inorganic coatings to improve surface properties.
    • Increases corrosion resistance, wear resistance, or provides decorative effects.
