Stainless Steel Bearing Characteristics and

Cixi Yongnuo 방위 Co., 주식 회사.

1. 440C Stainless Steel Bearings

• Material Properties: High-carbon martensitic stainless steel, heat-treated to achieve 인사말 58-60 hardness.

• 기능:

  • Exceptional wear resistance and high load capacity.

  • Moderate corrosion resistance (suitable for dry or mildly corrosive environments).

  • Ideal for high-speed, high-stress applications (e.g., precision machinery, aerospace).

• Limitations: Less corrosion-resistant than austenitic grades; requires lubrication in harsh conditions.

2. 440 Stainless Steel Bearings

• Material Properties: Medium-carbon martensitic steel with slightly lower hardness (인사말 56-58) than 440C.

• 기능:

  • Good wear resistance and moderate corrosion resistance.

  • Cost-effective for medium-load applications (e.g., automotive components, industrial tools).

• Limitations: Avoid prolonged exposure to saltwater or acidic environments.

3. 420 Stainless Steel Bearings

• Material Properties: Low-carbon martensitic steel with 인사말 50-55 hardness.

• 기능:

  • Better corrosion resistance than 440 series due to lower carbon content.

  • Suitable for low-to-medium load applications requiring moderate corrosion resistance (e.g., food processing, medical instruments).

• Limitations: Lower hardness limits use in high-wear scenarios.

4. 304 (AISI 304) Stainless Steel Bearings

• Material Properties: Austenitic stainless steel with HB 150-200 hardness (non-heat-treatable).

• 기능:

  • Excellent corrosion resistance in oxidizing environments (e.g., water, mild chemicals).

  • Hygienic and easy to clean, ideal for food, beverage, 및 제약 산업.

• Limitations: Lower hardness and wear resistance; avoid high-load/high-speed use.

5. 316 (AISI 316) Stainless Steel Bearings

• Material Properties: Austenitic steel with molybdenum addition for enhanced corrosion resistance.

• 기능:

  • Superior resistance to chlorides and acidic environments (e.g., 해병, chemical processing).

  • Biocompatible and sterilizable, suitable for medical and marine applications.

• Limitations: Softer than martensitic grades; not recommended for high-wear scenarios.
