Aiman Metals, located in Kuala Lumpur, Malaysia, is a reputable manufacturer and supplier known for its high-performance tool steels, including M2 steel bars and rods. With a strong focus on quality, precision, and customer satisfaction, Aiman Metals caters to a diverse array of industries both in Malaysia and beyond. The company provides M2 steel in various sizes and dimensions tailored to meet the unique requirements of clients in tooling, manufacturing, and engineering. With years of industry experience and a robust supply network, Aiman Metals ensures that its premium-grade products meet international standards for durability, hardness, and performance.
M2 steel, often referred to as high-speed steel (HSS), typically comprises 0.85% carbon, 6.0% tungsten, 5.0% molybdenum, 4.0% chromium, and 2.0% vanadium, along with a trace of cobalt. This specific blend results in remarkable wear resistance and hardness. After heat treatment, M2 steel achieves a high hardness level of around 62–65 HRC, along with impressive compressive strength and excellent edge retention during high-speed operations. It retains its hardness even at elevated temperatures, making it perfect for cutting applications. The combination of toughness and hardness guarantees a long tool life in challenging industrial settings.
