Understanding the Composition and Uses of BM2 Steel Grade

BM2 steel grade is a type of high-speed tool steel, which is commonly used in the manufacture of cutting tools such as drills, taps, reamers, and milling cutters. This steel grade is known for its excellent wear resistance, hardness, and toughness, making it suitable for high-speed machining operations.

The chemical composition of BM2 steel grade typically includes:
– Carbon (C): 0.82-0.90%
– Manganese (Mn): 0.15-0.40%
– Silicon (Si): 0.15-0.45%
– Chromium (Cr): 3.80-4.50%
– Vanadium (V): 1.7-2.1%
– Molybdenum (Mo): 4.70-5.20%

The mechanical properties of BM2 steel grade include:
– Hardness: 62-64 HRC
– Tensile strength: 2700-2800 MPa
– Yield strength: 2400-2500 MPa
– Elongation: 2-3%

Due to its composition and properties, BM2 steel grade is often used in the manufacture of cutting tools that require high resistance to wear and deformation at high temperatures. Its excellent combination of hardness and toughness makes it suitable for demanding machining applications, particularly in the aerospace, automotive, and manufacturing industries.
