GB/T T8 Free Cutting Steel
The usage is:
1. Drill bits: T8 is often used to manufacture drill bits for drilling holes in metal, wood, and other materials. Its high hardness and wear resistance ensure long-lasting performance and efficient cutting.
2. Taps and dies: High-speed steel with T8 specification is also commonly used to make taps and dies for threading operations. Its toughness and heat resistance make it suitable for cutting threads in various materials.
3. Milling cutters: T8 high-speed steel is used to produce milling cutters for shaping and profiling metal workpieces. Its sharp cutting edges and wear resistance allow for precise and efficient machining operations.

DIN 1.1525 Free Cutting Steel
| 1: T8 steel introduction Tool steels are high quality steels developed with controlled chemical composition to form properties essential for working and shaping of other materials. They are normally delivered to the suppliers in the soft annealed condition, which makes it easy for the manufacturer to machine the material with cutting tool for different applications.AISI T8 tool steel is a tungsten-cobalt-vanadium high-speed tool steel. The following datasheet will provide an overview of grade T8 tool steels. 2: DIN 1.1525 steel chemical composition |

5: Heat Treatment
Annealing: Annealing temperature/℃: 750~790; After the annealing, degree of hardness ≤HBS: 225
Quenching: Hardening temperature/℃: 1277, Quenching in oil or air
Tempering: Commonly used drawing temperature/℃:552; After tempering hardness HRC : 63 HRc Min
Normalizing：at Normalizing temperature, then cool in furnace
For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
