Tool Steel refers to a variety of carbon and alloy steels that are particularly well-suited to be made into tools. Tool steels are notable for their hardness, resistance to abrasion and deformation. Today, tool steel is widely used in various specific tool applications like dies, cutting, mold-making and hammers (personal or industrial). Tool Steel can retain a cutting edge at very high temperatures which is why they are often used in the shaping of other materials through cutting, pressing, coining or extruding. Their resistance to abrasion lends to their use in the production of injection molds.
The global market for Tool Steel is estimated to increase from US$ 7667.5 million in 2024 to reach US$ 8616.2 million by 2031, exhibiting a CAGR of 1.7% during 2025-2031.

| ※参考情報 ツール用鋼(Tool Steel)は、主に工具や金型の製造に使用される鋼の一種であり、その特性により高い耐摩耗性、耐熱性、および硬度を備えています。工具用鋼は、切削工具、成形工具、打撃工具など、さまざまな用途で使用されており、その性能を最大限に引き出すために、適切な合金成分と熱処理プロセスが重要視されています。 ツール用鋼の定義は比較的明確であり、通常、特定の合金成分を含み、熱処理によって硬化した鋼材を指します。この鋼は、主に高炭素鋼として分類されますが、合金元素を添加することで、その特性をさらに向上させることが可能です。これにより、ツール用鋼は通常の炭素鋼よりも高い硬度や耐摩耗性を備えています。 ツール用鋼の特徴として、まず第一に高耐摩耗性があります。多くの工具は摩擦や衝撃に晒されるため、摩耗に強い素材が必要です。また、耐熱性も重要な特性であり、高温でもその硬さを維持できることが求められます。このため、様々な合金元素が添加され、鋼自体の構造を強化しています。さらに、加工性も考慮されており、鋼の硬度が高すぎると加工が難しくなるため、適切なバランスが必要です。 ツール用鋼は大きく分けていくつかの種類に分類されます。一般的な分類としては、以下のものが挙げられます。 1. 高速鋼(HSS):鋼の中でも特に耐摩耗性と耐熱性に優れ、主に切削工具に使用されます。切削条件が厳しい場合にもその性能を発揮します。 2. 冷間圧延用鋼:冷間成形用の工具に使用される鋼であり、硬度や靭性を兼ね備えた特性が求められます。 3. 熱間用鋼:高温での使用に耐え、熱間成形などに使用される鋼です。オーステナイト鋼またはマルテンサイト鋼が一般的です。 4. プラズマ焼入れ鋼:表面硬化処理が施された鋼で、摩耗抵抗性が高まり、耐久性が向上します。 5. 刃物鋼:刃物やカッター用の特別な鋼で、繊細な刃先を持つことが求められます。 ツール用鋼の用途は非常に広範囲にわたります。まず、製造業における切削工具としての用途が最も一般的です。ボーリング、フライス、旋盤といった加工工具に使用される他、ミルやドリルなど、高速回転する工具にも使われています。また、金型やプレス金型、鋳型など、多くの成形工具にも使用されており、材料を目的の形状に成形する際に欠かせない存在となっています。 医療分野にもツール用鋼は用いられています。たとえば、外科器具や医療用刃物などは、耐腐食性や耐久性が求められ、ツール用鋼が適用されるケースが多くあります。さらに、自動車や航空宇宙産業でも部品の製造に使用され、特に高い精度が求められる環境での利用が増加しています。 近年の製造技術の進展により、ツール用鋼も進化を遂げています。特に注目されるのは、粉末冶金技術による新しいタイプのツール用鋼の開発です。この技術により、非常に均一な微細構造を持つ鋼材が得られ、耐摩耗性や靭性がさらに向上しています。粉末冶金によって得られる鋼は、従来のツール用鋼に比べて高性能であり、切削工具や塑性加工工具の分野で注目されています。 また、環境への配慮から、リサイクル技術も進化しています。ツール用鋼のリサイクルは、製造過程での資源の節約やコスト削減に寄与しています。使用済みの工具や部品から再生鋼を製造することで、新しい製品の材料として活用されるため、持続可能な社会に向けた重要なステップといえるでしょう。 さらに、数値制御技術(CNC)や自動化技術の進展もツール用鋼の需要に大きな影響を与えています。高度な加工が可能になることで、ツールの設計や製造プロセスが効率化され、より高精度な工具の製造が可能となりました。これにより、一層競争の激しい市場での生き残りが求められます。 ツール用鋼は、その特性や用途から、多くの産業において不可欠な素材であることが理解できます。特に、高度な耐摩耗性、耐熱性、加工性が求められる環境では、その重要性はますます高まっています。今後も新たな技術革新によって、ツール用鋼の特性向上が期待され、さまざまな分野での活用が進むことでしょう。 |
