M35 High Speed Tool Steel

↵

M35 High Speed ​​Tool Steel is a cobalt-containing high-speed tool steel, manufactured according to the ASTM A600 standard, and is mainly used to manufacture cutting tools that operate under medium and high temperature cutting conditions.

Secondary Hardening - During tempering, Mo (4.5–5.2%) and W (5.5–6.7%) form fine carbide precipitation, resulting in a secondary hardening effect to maintain hardness levels at high temperatures.

High-Temperature Hardness Retention - With a Co content of 4.5–5.0%, the material improves hardness retention under elevated temperatures after tempering by influencing the matrix phase transformation behavior, making it suitable for high-temperature cutting environments.

Wear Resistance - C (0.87–0.95%) and V (1.7–2.1%) form high-hardness carbides, slowing the edge wear rate and extending geometry retention time during cutting.

Multiple Sizes Available - Suitable for round bars with diameters of 5–200 mm and flat bars with thicknesses of 6–80 mm (maximum width 300 mm), and supports custom plate cutting, suitable for machining tool blanks of various sizes.

Cutting tool manufacturing industry: Used to manufacture cutting tools such as drills, end mills, and reamers, bearing the responsibility for material removal and cutting edge load during machining.

Threading industry: Used in the manufacture of taps and dies, bearing the torque and friction during thread forming.

Die and precision machining industry: Used to manufacture cold-working punches and locally high-wear parts, maintaining dimensional contours during repeated contact.

General machining industry: Used for tool components under high-load conditions, participating in material cutting and surface formation during continuous machining.
