Supply T5 High Speed Steel

What is T5 high speed steel? It is a tungsten-based cobalt-containing high-speed steel with high hardness and excellent performance. T5 high-speed steel has uniform and fine carbide distribution, high purity and stable performance. It is the best material in the field of cutting processing. And after it is properly quenched and tempered, it has excellent toughness and wear resistance, which allows it to maintain a sharp edge for a longer period of time during the cutting process, reduce wear, and improve cutting efficiency and tool life.

This article will give you a detailed understanding of the equivalent specifications, chemical composition, properties, application, heat treatment and supply scope of T5 high speed steel supplied by Songshun Steel.

T5 High Speed Steel Equivalent Specification

China GB /T 9943 standard: GB W18Cr4V2Co 8
American ASTM A600 standard: AISI/SAE/ASTM T5
German DIN EN ISO 4957 standard: DIN EN/DIN S18-1-2-10 / W-Nr. 1.3265
Japanese JIS G 4403 standard: JIS SKH 4

T5 high speed steel contains up to 9.5% cobalt, which makes its high-temperature performance and toughness better than T4 high speed steel, while also having good hot hardness and cutting ability. It also contains a large amount of W element, which can form hard tungsten carbide at high temperatures and improve the hardness, high-temperature strength and wear resistance of T5 steel.

AISI T5 High Speed Steel Properties

  • High hardness and wear resistance

After T5 high-speed steel is quenched, the surface hardness can reach 64-70HRC, which can maintain cutting performance for a long time under high-speed and heavy-load conditions, resist wear and tear of cutting tools during use, and improve cutting efficiency and tool life.

  • Excellent cutting performance

T5 steel has excellent cutting edge durability, high cutting efficiency, good cutting stability, can achieve high-speed cutting, and also extends tool life. And it is suitable for difficult-to-machine materials with large cutting volume, high cutting efficiency, large feed volume and high hardness.

  • Good toughness and thermal stability

AISI T5 high speed steel has good fracture resistance and tensile resistance, can withstand large impact loads and vibrations, and can maintain the integrity of the tool. It can also maintain stable performance in high temperature environments, has good high temperature resistance and softening resistance, and is suitable for high temperature cutting and various complex processing environments.

In addition, T5 high speed steel also has good corrosion resistance, high strength, easy heat treatment, is suitable for a variety of processing occasions, and is easy to sharpen and repair.

T5 High Speed Steel Application

T5 high speed steel is widely used and is often used to manufacture various cutting tools, turning tools, broaches, punches, drill bits, forming cutting tools, twist drills, milling cutters, hobs, thread molds, engine parts, molds, and planers. , gear cutters, shafts, gears, cold stamping dies, etc.

T5 High Speed Steel Heat Treatment

1.Quenching
Usually, T5 high speed steel is preheated to 820~870℃, then quickly heated to the quenching temperature of 1270~1290℃ (salt bath furnace) or 1280~1300℃ (box furnace), kept warm for a period of time, and finally heated in water and oil. , or rapid cooling in air to obtain austenite structure and high hardness.

2.Tempering
After quenching, the T5 high-speed steel is sublimated in tempering at 540 to 560°C. It is tempered twice and held for at least 2 hours each time to reduce residual stress and improve toughness and stability.

3. Harden
Slowly preheat T5 tool steel to 820-870°C, then evenly heat to austenitizing temperature, salt bath 1277°C, controlled atmosphere furnace 1288°C, then salt bath or thermal quenching or warm bath about 550°C.

AISI/ASTM T5 High Speed Steel Supply

Shape types: round bar, steel plate, tube, round bar, thin plate, forging, forged pipe, forged plate, square steel, plate, seamless tube, flat steel, thick plate, bar, etc.
