Understanding the Properties and Applications of 41CrAlMo7 Steel Grade

[ad_1] 41CrAlMo7 is a low-alloy steel grade with a chemical composition containing chromium, aluminum, molybdenum, and carbon. The specific composition is as follows:

– Carbon (C): 0.38-0.45%
– Silicon (Si): 0.40% max
– Manganese (Mn): 0.60-0.90%
– Phosphorus (P): 0.035% max
– Sulfur (S): 0.040% max
– Chromium (Cr): 0.70-1.10%
– Nickel (Ni): 1.0% max
– Copper (Cu): 0.30% max
– Aluminum (Al): 1.25-1.75%
– Molybdenum (Mo): 0.25-0.35%

Mechanical properties of 41CrAlMo7 steel grade include a tensile strength of 900-1100 MPa, a yield strength of 750-900 MPa, and an elongation of 16-18%. This steel grade exhibits good hardenability, high strength, and excellent wear resistance.

Applications of 41CrAlMo7 steel grade include manufacturing of high-stress components such as gears, shafts, and other mechanical parts requiring high strength and wear resistance. It is commonly used in the automotive and aerospace industries, as well as in the production of heavy machinery and equipment.
