ESR M35 (DIN 1.3243) high-speed tool steel is a high-performance alloy steel known for its excellent wear resistance and toughness, widely used in machining applications that involve high heat and stress. Manufactured through the Electric Arc Remelting (ESR) process, M35 steel offers superior uniformity and purity, delivering improved mechanical properties and heat resistance. The high cobalt content of M35 steel makes it ideal for high-speed cutting, grinding, and other high-temperature machining tasks, especially in the production of complex tools, dies, drill bits, and end mills. Its outstanding red hardness and wear resistance enable stable, long-lasting performance under heavy load conditions.

This high-speed steel has excellent heat treatment properties, maintaining high hardness while providing exceptional toughness, making it suitable for machining high-strength materials and precision applications. Whether in the tool manufacturing industry, aerospace, automotive, or mold making, M35 steel ensures reliable cutting performance, making it the ideal choice for producing high-precision cutting tools and molds.

Heat Treatment of ESR M35 / 1.3243 High Speed Tool Steel:

1. Annealing

   • Hardness (HB): 269
     Annealing softens the steel to reduce internal stresses and improve machinability.

2. Hardening

   • Temperature: 1200-1220°C
     The steel is heated to this temperature range to increase hardness and strength.

3. Tempering

   • Temperature: 550°C
     Tempering at 550°C helps to reduce brittleness while maintaining strength and wear resistance.

4. Tempered Hardness (HRC): 64-67
   After tempering, the hardness of the steel is in the range of 64-67 HRC, offering a good balance of toughness and hardness for machining tasks.
