Grade Brief
Goel Steel Company is one of India’s largest suppliers and stockists of M2 High Speed Steel Powder Metallurgy steels, known for their high-performance properties. With a balanced alloy composition, M2 steel offers outstanding toughness and cutting-edge retention, making it an adaptable choice for numerous applications. It is widely used in metal-cutting tools like twist drills, milling cutters, broaches, reamers, thread dies, and woodworking tools. M2 is also ideal for cold-forming tools, including extrusion rams and dies, precision cutting tools, wear-resistant plastic molds, and fasteners.
As a general-purpose, molybdenum-type high-speed steel, M2 High Speed Steel Powder Metallurgy steels combine high toughness, wear resistance, and red hardness, performing excellently in applications such as cold work punches, dies, and high-speed, light-cutting tools. Due to greater bending strength, toughness, and thermoplasticity—50% more than T1 steel—M2 is preferred over T1 in most applications, dominating high-speed steel production worldwide. M2 tools can also be coated with titanium nitride, titanium carbide, and other physical vapor deposition coatings for improved durability and performance.
Mode of Supply
Goel Steel Company stocks M2 High Speed Steel Powder Metallurgy steels in various sizes and forms, including flat, square, and round bars, customized to meet specific client requirements. Our team is prepared to support any M2 steel inquiries.

Physical Properties
Thermal conductivity of M2 High Speed Steel Powder Metallurgy steels varies with temperature, showing 32.8 W/(mK) at 20°C, 23.5 W/(mK) at 350°C, and 25.5 W/(m*K) at 700°C.
Forging DIN 1.2085 Material
For optimal results, 1.2085 steel should be forged at temperatures between 800-1100°C, followed by slow cooling to maintain its excellent properties.
Heat Treatment & Processes
Heat Treatment
Rapid heating from 2610°C (4730°F) to 3960°C (7160°F) after preheating, with quenching in air, a salt bath, or oil.
Hardening
Preheat twice (450–500°C and 850–900°C) before reaching the final hardening temperature of 1200–1250°C, avoiding extended exposure.
Quenching
Use heated oil, pressurized gas, or salt; pressurized gas requires a quick quench rate below 1000°F (538°C).
Tempering
Immediate tempering post-quenching at 1025–1050°F, with two-hour holds before air cooling to ambient. Dual or triple tempering is advised for larger sections.
Forging
Preheat to 850–900°C, forge between 1050–1150°C, and cool slowly.
Stress Relieving and Annealing
Preheat and controlled cooling procedures minimize stress, especially in complex tools.
Nitriding
Carried out at 500–600°C in a nitrogen-rich environment to improve surface characteristics.
Welding and Soft Annealing
Weld at 1100°F (600°C) with controlled cooling; soft annealing recommended at 770-860°C, with a max hardness of 269 HB.
Applications of 1.2085 Steel
M2 High Speed Steel Powder Metallurgy steels from Goel Steel Company serve a broad spectrum of metal-cutting and cold-forming applications, with high wear resistance for tools like twist drills, thread dies, reamers, precision-engineered tools, molds, and more, supporting various industrial needs.
