style="text-indent:25px">工具鋼材在切割工具中的硬鋼。這一組中流行的鋼材主要包括D2、O1和CPM系列；比較典型的高碳工具鋼W2，其含碳量比較高可達(dá)15%；還有像M4這種更先進(jìn)的多切鋼。鋼材一般來說制作相對(duì)粗糙，用于特別需要韌性和耐久性的地方。鋼材常用在救生刀和大刀中，它邊緣鋒利，相對(duì)而言容易打磨。鋼材基本的碳鋼添加鉻元素使其抗腐蝕，加入其它元素提高其性能，但是要以降低韌性為代價(jià)。鋼材運(yùn)用的是第三代粉末金屬技術(shù)，需要優(yōu)越的抗腐蝕性和非常高的硬度來保證其耐磨性。鋼材加入了鉻、鉬、釩、鎢以提高鋒利度和優(yōu)越的鋒利保持度。硬度達(dá)到60-62HRC。</p><p style="text-indent:25px">耐磨性是鋼材承受磨蝕和黏著磨損的能力。磨蝕是由于較軟的表面和較粗糙的表面接觸而形成的。黏著磨損是當(dāng)碎片從一個(gè)表面上轉(zhuǎn)移，附著在另一表面上時(shí)形成的。耐磨性一般是與鋼材的硬度有關(guān)聯(lián)的，但是很大程度上也受到鋼材中具體化學(xué)物質(zhì)的影響。在同等硬度的鋼材中，碳化物含量越大的鋼材越耐磨。耐腐蝕性是指抗腐蝕的能力，像由潮濕、水分、鹽漬等因素引起的銹蝕。請(qǐng)注意，高度的耐腐蝕能力確實(shí)要以降低刀鋒的鋒利程度為代價(jià)。鋒利保持度表示，當(dāng)一把刀使用一段時(shí)間后，刀片的鋒利能夠保持多久，這是耐磨性和刀鋒抗變形能力的結(jié)合。鋼材可以按照品質(zhì)分類，按成形方法分類。</p><div
