Product Description

AISI T8/DIN 1.6580 cold work tool steel
T8 steel, also known as 1.6580 steel, is a medium carbon alloy steel with excellent wear resistance, toughness, and hardenability. It is widely used in various industrial applications where high strength, durability, and abrasion resistance are required.

Chemical Composition:

Element	Composition (%)
Carbon (C)	0.70-0.80
Silicon (Si)	0.20-0.40
Manganese (Mn)	0.40-0.60
Phosphorus (P)	≤0.035
Sulfur (S)	≤0.035
Chromium (Cr)	0.40-0.60
Nickel (Ni)	≤0.30
Molybdenum (Mo)	≤0.20

Properties:
1.High Wear Resistance: T8 steel exhibits excellent wear resistance, making it suitable for applications involving abrasive wear, such as cutting, machining, and forming tools.
2.Good Toughness: Despite its high hardness, T8 steel retains good toughness, reducing the risk of chipping and fracture during use.
3.High Hardenability: T8 steel has excellent hardenability, allowing it to achieve high hardness and strength through heat treatment processes.
4.Good Machinability: T8 steel can be machined easily in the annealed or normalized condition, enabling the production of complex shapes and precise components.
5.Dimensional Stability: T8 steel maintains dimensional stability during heat treatment and prolonged use, minimizing distortion and ensuring dimensional accuracy in finished parts.
6.Versatile Applications: T8 steel is widely used in various industrial applications, including tool and die making, automotive components, machinery parts, and construction equipment.

Heat Treatment:
T8 steel undergoes heat treatment processes to optimize its mechanical properties:
Annealing: Heat to 800-850°C, followed by slow cooling in the furnace to relieve internal stresses and refine the grain structure.
Hardening: Heat to 850-880°C, followed by oil quenching to achieve maximum hardness.
Tempering: Tempering temperature ranges from 150°C to 550°C, depending on the desired hardness and toughness requirements.

Surface Treatment:
Surface treatments such as nitriding, carburizing, or coating with wear-resistant materials can further enhance the performance and longevity of T8 steel components in demanding applications.

Applications:
T8 steel is commonly used in the manufacturing of:
1.Cutting tools such as drills, milling cutters, and taps for metalworking and machining operations.
Machine components including gears, shafts, and bearings requiring high strength and wear resistance.
2.Dies and molds for forging, stamping, and injection molding processes in the automotive, aerospace, and plastics industries.
3.Structural components in construction, mining, and heavy machinery applications.

Quality Assurance:
T8 steel is produced and processed according to international standards such as ASTM A29/A29M or equivalent, ensuring consistent quality, mechanical properties, and performance in various applications.

Environmental Considerations:
In the production and processing of T8 steel, environmental considerations such as energy efficiency, waste management, and emissions control should be addressed to minimize environmental impact and promote sustainability in the industry.
