M2 tool steel is a highly versatile, general-purpose high-speed tool steel that provides a good balance of toughness, wear resistance, hot hardness, and heat treatability, making it suitable for a broad spectrum of cutting, forming, and structural applications.<\/p>\n\n\n\n

1. Applications<\/h2>\n\n\n\n
    \n
  • General-Purpose Cutting Tools<\/strong><\/li>\n\n\n\n
  • Single-Point Cutting Tools: <\/strong>They can machine a wide range of materials, including wrought steel, cast steel, cast iron, brass, bronze, copper, and aluminum.<\/li>\n\n\n\n
  • Drills: <\/strong>M2 material is the universal choice for general-purpose drills.<\/li>\n\n\n\n
  • Milling Cutters: <\/strong>More than 70% of free-machining milling cutters are made of M2 material.<\/li>\n\n\n\n
  • Saws: <\/strong>M2 high-speed tool steel is the general-purpose saw material.<\/li>\n\n\n\n
  • Other Applications: <\/strong>M2 hss is used as a core and ejector pin material in plastic injection molding tools. Also used for structural applications, such as machine elements, cams, shafts, spindles, gears, and sprockets.<\/li>\n<\/ul>\n\n\n\n

    3. M2 Tool Steel Properties<\/h2>\n\n\n\n

    M2 tool steel stands as a cornerstone in the high-speed steel (HSS) family, and for many good reasons, it\u2019s a popular choice for a wide array of demanding applications. This molybdenum-based HSS, part of the \u201cM\u201d series, delivers a reliable combination of hardness, wear resistance, and toughness, making it a versatile workhorse. <\/p>\n\n\n\n

    3.1 Hardness<\/h3>\n\n\n\n

    El M2 tool steel hardness<\/em> is very high, and through hardening and tempering, its working hardness ranges from 60 to 65 HRC.<\/p>\n\n\n\n

    3.2 Wear Resistance<\/h3>\n\n\n\n

    Extremely high wear resistance.<\/p>\n\n\n\n

    3.3 Hot Hardness (Tempering Resistance)<\/h3>\n\n\n\n

    Good thermal hardness, meaning that it can maintain its hardness and strength even under high-temperature working conditions. While some specialized HSS grades might offer higher hot hardness, M2 material performs reliably in typical high-temperature tooling scenarios.<\/p>\n\n\n\n

    3.4 Toughness<\/h3>\n\n\n\n

    M2 steel has such high hardness and wear resistance while maintaining good toughness. Tool steel M2 produced by powder metallurgy (P\/M) processes has higher toughness.<\/p>\n\n\n\n
