Diving into the Technical Specifications of BM2 Steel Grade

BM2 steel grade is a high-speed steel that is commonly used in cutting tools and cold working applications. It offers excellent performance in terms of wear resistance, toughness, and hardness. Let’s take a closer look at the technical specifications of BM2 steel grade, including its chemical composition and mechanical properties.

Chemical Composition:
The chemical composition of BM2 steel grade typically includes high levels of carbon, tungsten, molybdenum, vanadium, and chromium. The exact composition may vary slightly depending on the manufacturer, but a typical composition range is as follows:

– Carbon (C): 0.78-0.88%
– Tungsten (W): 5.00-6.60%
– Molybdenum (Mo): 4.50-5.50%
– Vanadium (V): 1.70-2.0%
– Chromium (Cr): 3.80-4.40%

Other elements such as silicon, manganese, and sulfur may also be present in smaller amounts, contributing to the overall properties of the steel.

Mechanical Properties:
BM2 steel grade offers excellent mechanical properties that make it suitable for demanding applications. The typical mechanical properties of BM2 steel grade include:

– Hardness: 63-65 HRC
– Tensile Strength: 2450-2550 MPa
– Yield Strength: 2050-2150 MPa
– Elongation: 4-6%

These mechanical properties make BM2 steel grade well-suited for high-speed cutting and cold working operations, where wear resistance, toughness, and hardness are crucial factors for performance.

Overall, BM2 steel grade is a high-performance material with a well-balanced combination of chemical composition and mechanical properties, making it a popular choice for applications that require high-speed cutting and cold working capabilities.
