Product Description:
T1 is a high-carbon, tungsten-based high-speed tool steel that is known for its excellent hardness, wear resistance, and ability to retain strength at high temperatures. T1 tool steel is often used in the production of cutting tools, such as drills, taps, and milling cutters, and is recognized for its exceptional red hardness, which makes it ideal for high-speed cutting applications. It is primarily used in industries where tools are exposed to high thermal stresses and must maintain sharpness at elevated temperatures, such as in metalworking, automotive, and aerospace sectors. T1 is one of the oldest and most widely used high-speed steels due to its toughness and excellent performance in high-temperature environments.
Features:
- High Red Hardness: T1 maintains its hardness even at elevated temperatures (up to 600°C or 1112°F), making it ideal for high-speed machining and cutting tools.
- Excellent Wear Resistance: The tungsten content provides superior wear resistance, making T1 ideal for tooling applications that require high abrasion resistance.
- Good Toughness: T1 balances high hardness with toughness, reducing the risk of brittleness and failure under stress.
- High Strength: T1 offers high tensile strength and can withstand heavy cutting forces without losing performance.
- Good Grindability: T1 can be ground to precise tolerances, making it suitable for high-precision tool-making.
- Ability to Retain Sharp Edges: T1 maintains sharp cutting edges for longer durations compared to other steels, improving the efficiency and lifespan of cutting tools.
Specifications:
- ASTM A600: Standard Specification for High-Speed Tool Steel, which includes T1.
- SAE J438: Standard for high-speed tool steels, including T1.
- UNS T12002: Unified Numbering System designation for T1 tool steel.
