Supply T1 High Speed Steel

What is T1 high speed steel? It is a widely used tungsten-based high-speed tool steel with high hardness, red hardness and high temperature hardness, it is also an innovative and efficient material. Usually T1 high-speed steel can have excellent properties through reasonable alloy proportions and precise processing methods. It is widely used in cutting tools, automobile manufacturing, mold manufacturing and other fields, and is an indispensable and important material in many fields. Here, this article will take you to learn more about the equivalent specifications, chemical composition, properties, application and supply scope of the T1 high speed steel supplied by Songshun Steel.

AISI T1 High Speed Steel Equivalent Specification

Equivalent grade of T1 high speed steel:
China GB /T 9943 standard: GB W18Cr4V
American ASTM A600 standard: AISI/SAE/ASTM T1
German DIN EN ISO 4957 standard: DIN HS18-0-1 / DIN S18-0-1 / DIN 1.3355
British BS 4659 standard: BS BT1
Japanese JIS G 4403 standard: JIS SKH / JIS SKH2

These equivalent grades have similar chemical composition and mechanical properties, making them interchangeable in many applications.

T1 High Speed Steel Chemical Composition

Chemical CompositionContent (%)

As can be seen from the table, T1 high speed steel contains a large amount of W element. The addition of tungsten can significantly improve the hardness, thermal stability and wear resistance of T1 high-speed steel, making it suitable for application fields such as high-speed cutting and cold work molds. It may also contain small amounts of other elements such as nickel (Ni), cobalt (Co) and niobium (Nb), and control of these chemical compositions can adjust the steel’s properties to some extent.

T1 High Speed Steel Properties

  • Excellent hardness and wear resistance: After quenching and tempering, the hardness of T1 tool steel can reach 61-66HRC, and the addition of tungsten and molybdenum can improve its wear resistance, which makes it suitable for processing high hard materials and perform heavy-duty cutting.
  • Excellent cutting performance: It can maintain stable cutting performance under high temperature and high-speed cutting conditions, effectively extending the service life and production efficiency of the tool.
  • Excellent hardenability: The addition of tungsten and molybdenum improves the hardenability of T1 steel, allowing it to form a uniform martensite structure at a faster quenching speed.
  • Good high temperature resistance: It can maintain good thermal stability and thermal fatigue resistance at high temperatures, and can resist high temperature softening and deformation.
  • Good toughness: Appropriate heat treatment improves its toughness, has high fracture toughness and impact resistance, can withstand large impacts and vibrations during cutting, and improves the service life of the tool.

In addition, it also has excellent durability, long service life, good rigidity and corrosion resistance, good resistance to plastic deformation, etc.

ASTM T1 High Speed Steel Application

T1 high speed steel is used in many fields, including tool manufacturing, automobile manufacturing, aerospace, plastic processing, machining and metallurgy, etc. It is also widely used in manufacturing various cutting tools and accessories, including milling cutters, turning tools, cutting tools Rods, drill bits, tool holders, clamps, planers, blades, thread cutters and more. It is also used to manufacture various punches, punch parts, high-temperature parts, molds, etc.

T1 High Speed Steel Heat Treatment

1.Quenching: It is usually preheated to 820~870°C, then heated to the critical temperature (usually 1250-1300°C), heated by a salt bath furnace or box furnace, and cooled by oil.

2. Tempering: After quenching, heat the T1 high-speed steel to 500-600°C and maintain it for a certain period of time. Temper twice, for 1 hour each time;

In addition to quenching and tempering, depending on the requirements, normalizing, isothermal quenching, etc. can also be performed to improve the performance of T1 high-speed steel.
