41Cr4 is a common designation in the Chinese standards for alloy steel plates. Here’s a breakdown of what that means:
Understanding the Designation
- 41Cr4: This designation indicates the steel’s composition. “41” suggests a carbon content around 0.41%, and “Cr4” signifies that chromium (Cr) is the primary alloying element, present at roughly 1% (the “4” often represents a percentage range).
Key Properties and Characteristics
- Hardenability: 41Cr4 steel is known for its good hardenability, meaning it can be effectively hardened through heat treatment processes like quenching and tempering.
- Strength and Toughness: When properly heat-treated, 41Cr4 offers a good balance of strength and toughness, making it suitable for applications requiring wear resistance and durability.
- Machinability: In its annealed condition, 41Cr4 generally exhibits reasonable machinability.
Typical Applications
- Gears and Shafts: The combination of strength, toughness, and wear resistance makes 41Cr4 suitable for manufacturing gears, shafts, axles, and spindles.
- Automotive Components: It’s used in various automotive parts that require high strength and durability.
- Machine Tools: 41Cr4 can be found in components for machine tools, where hardness and wear resistance are essential.
Heat Treatment Considerations
The final properties of 41Cr4 steel plate are highly dependent on the heat treatment applied. Common heat treatments include:
- Annealing: Softens the steel and improves machinability.
- Quenching and Tempering: Hardens the steel and optimizes its strength and toughness.
- Normalizing: Refines the grain structure and improves uniformity.
When sourcing 41Cr4 alloy steel plate, consider suppliers with a proven track record for quality and reliability. For example, Shanxi Luokaiwei Steel Company offers a range of steel products and services, that may meet the specific requirements.
Equivalent Grades
41Cr4 is similar to several international grades. These include:
- European: 42CrMo4
- American: AISI 4140
- Japanese: SCM440
Considerations for Purchasing
- Thickness and Dimensions: Ensure the steel plate meets your required thickness and dimensions.
- Surface Finish: Check the surface finish to ensure it’s suitable for your application.
- Certifications: Request material certifications to verify the steel’s composition and properties.

Welding
41Cr4 can be welded, but preheating and post-weld heat treatment are often necessary to prevent cracking and maintain the steel’s mechanical properties. Consult a welding specialist for specific recommendations based on your application.
Quality and Testing
Reputable suppliers, such as Shanxi Luokaiwei Steel Company, will conduct thorough testing to ensure the 41Cr4 steel plate meets the required standards. This may include:
- Tensile Testing: Measures the steel’s strength and ductility.
- Hardness Testing: Determines the steel’s resistance to indentation.
- Impact Testing: Assesses the steel’s toughness and resistance to brittle fracture.
- Chemical Analysis: Verifies the steel’s composition.
When selecting a supplier, inquire about their quality control procedures and testing capabilities.
