Neil Metals, located in Kolkata, India, has made a name for itself as a trusted manufacturer and supplier of top-notch High Speed Steel M42 Bars. They cater to toolmakers, manufacturers, and various engineering sectors both in India and internationally. Known for their precision in manufacturing and a strong commitment to quality, Neil Metals produces M42 bars that excel in wear resistance, cutting efficiency, and hot hardness. With state-of-the-art infrastructure and a team of experienced technical support, the company offers customized sizes and quick delivery to meet the unique needs of their customers. Neil Metals stands out as a dependable partner for industries that require high-performance materials for machining, metalworking, and high-speed cutting tasks.
High Speed Steel M42 Bars are cobalt-rich tool steels that contain about 1.10% carbon, 3.75–4.50% chromium, 9.00–10.00% molybdenum, 1.15% vanadium, and 7.75–8.75% cobalt, with the remainder being iron. This specific blend gives them remarkable red hardness, wear resistance, and edge retention. After heat treatment, M42 bars achieve a high hardness of 66–70 HRC and boast a tensile strength of around 1200–1400 MPa. They are well-known for maintaining cutting efficiency even at elevated temperatures, combining toughness and abrasion resistance, which makes them perfect for heavy-duty, high-speed machining and forming applications.

Yes, Incoloy 800 can be forged into custom shapes. Its excellent high-temperature resistance and strength make it suitable for various forging processes.
The ideal temperature range for forging Incoloy 800 is between 1,800°F to 2,200°F (982°C to 1,204°C). This range ensures optimal ductility and workability during the forging process.
To assess the forging strength of Incoloy 800 for aerospace applications, evaluate its tensile strength, yield strength, and fatigue resistance at elevated temperatures. Additionally, assess its performance under cyclic loads and long-term thermal stability.
High Speed Steel M42 Bars find extensive use in industries that demand exceptional cutting performance and durability under high-speed, high-temperature conditions. They are crucial in the production of cutting tools like drill bits, end mills, taps, reamers, gear cutters, and broaches. Additionally, M42 bars are utilized for precision cold work tools, dies, and punches. In sectors such as aerospace, automotive, and die-making, they excel at machining tough materials like stainless steel, titanium alloys, and hardened steels. Their impressive hot hardness and wear resistance ensure a longer tool life in high-demand production settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
