在工業(yè)生產(chǎn)中，模具鋼是模具工業(yè)的主體材料，模具的使用壽命和制成零件的精度、質(zhì)量、外觀性能，除與模具的設(shè)計(jì)技術(shù)、制造精度，以及機(jī)床精度和制造操作有關(guān)外，正確地選用模具材料和正確地執(zhí)行熱處理工藝也是至關(guān)重要的。模具的熱處理質(zhì)量和使用性能通常都以硬度作為判斷的依據(jù)硬度是模具材料和成品模具的重要性能指標(biāo)。模具在工作時(shí)的受力狀態(tài)是復(fù)雜的，如熱作模具通常是在交變的溫度場下承受交變應(yīng)力作用，因此它應(yīng)具有良好的阻止模具轉(zhuǎn)變成較軟或塑性狀態(tài)的能力，并且在長期工作環(huán)境下仍保持模具的形狀和尺寸精度不變。一般成品模具的硬度，冷作模具常選擇在59-60HRC，熱作模具常選擇在48HRC左右。耐磨性也是成品模具的重要性能指標(biāo)。零件成形時(shí)金屬和模具型腔表面發(fā)生相對運(yùn)動(dòng)，磨損了型腔表面，至使模具的尺寸形狀、精度和表面粗糙度發(fā)生變化而失效。模具的耐磨性是由模具的熱處理，特別是表面熱處理決定的，評估模具耐磨性好壞的主要依據(jù)也是硬度。模具鋼用硬度計(jì)測試主要針對三種情況，即模具鋼材料的硬度檢測，經(jīng)過熱處理的半成品模具的檢測硬度，要求高耐磨性的模具表面熱處理后的表面硬度檢測。模具鋼材料主要是經(jīng)過鍛造的鋼板、鋼塊或鋼棒，一般以退火狀態(tài)供貨。巴柯爾
