41Cr4 (also known by its Werkstoff number 1.7035) is a heat-treatable, low-alloy steel renowned for its good combination of strength, toughness, and wear resistance after appropriate heat treatment. It belongs to the chromium alloy steel group and is widely used in various engineering applications, particularly where components are subjected to moderate to high stresses.
Key Characteristics and Composition
The primary alloying element in 41Cr4 steel is chromium, which significantly enhances its hardenability and strength. Its typical chemical composition (weight %) is generally:
- Carbon (C): 0.38 – 0.45%
- Silicon (Si): ≤ 0.40%
- Manganese (Mn): 0.50 – 0.80%
- Phosphorus (P): ≤ 0.025%
- Sulfur (S): ≤ 0.035%
- Chromium (Cr): 0.90 – 1.20%
This composition allows 41Cr4 steel plates to achieve desirable mechanical properties through quenching and tempering.
Mechanical Properties and Heat Treatment
The mechanical properties of 41Cr4 steel plates are highly dependent on the heat treatment process. Typically, after quenching and tempering, it can exhibit:
- Tensile Strength: Often in the range of 800 – 1100 MPa, varying with tempering temperature.
- Yield Strength: Generally above 600 MPa.
- Toughness: Good impact strength, especially after proper tempering.
- Hardness: Can be controlled through tempering to suit specific application requirements.
Common heat treatments include normalizing, annealing, hardening by quenching (typically in oil or water), followed by tempering to achieve the desired balance of hardness and toughness. Suppliers like Shanxi Luokaiwei Steel Company often provide material in various heat-treated conditions or can advise on optimal treatments for specific applications.
Applications of 41Cr4 Steel Plate
Due to its favorable mechanical properties, 41Cr4 alloy steel plate is extensively used in the manufacturing of various components, including:
- Automotive parts: Axles, crankshafts, steering knuckles, gears, and connecting rods.
- Machinery components: Spindles, shafts, bolts, and studs.
- Tools: Hand tools and machine tool parts.
- Engineering components requiring good wear resistance and strength.
The versatility of 41Cr4 makes it a popular choice in demanding industrial sectors. Reputable suppliers, such as Shanxi Luokaiwei Steel Company, ensure the material quality meets stringent industry standards for these critical applications.
Supply and Considerations
