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、質量、外觀性能，除與模具的設計技術、制造精度，以及機床精度和制造操作有關外，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重要的。模具的熱處理質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。模具在工作時的受力狀態(tài)是復雜的，如熱作模具通常是在交變的溫度場下承受交變應力作用，因此它應具有良好的阻止模具轉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。零件成形時金屬和模具型腔表面發(fā)生相對運動，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。供應硬度機顯微硬度計是采用精密機械技術和光電技術的新型顯微維氏和努氏硬度測試儀器。</p><div

原于能工業(yè)用設備8、Cr12——常用的冷作模具鋼（美國鋼號D3，日本鋼號SKD1)特性和運用:Cr12鋼是一種運用***的冷作模具鋼，屬高碳高鉻類型的萊氏體鋼。該鋼具有較好的淬透性和杰出的耐磨性；由于Cr12鋼碳含量高達，所以沖擊韌度較差、易脆裂，并且容易形成不均勻的共晶碳化物；Cr12鋼由于具有杰出的耐磨性，多用于制作受沖擊負荷較小的要求高耐磨的冷沖模、沖頭、下料模、冷鐓模、冷揉捏模的沖頭和凹模、鉆套、量規(guī)、拉絲模、壓印模、搓絲板、拉深模以及粉末冶金用冷壓模等9、DC53——常用的日本進口冷作模具鋼特性和運用:**耐性冷作模具鋼，日本大同特殊鋼（株）廠家鋼號。高溫回火后具有高硬度、高耐性，線切割性杰出。用于精細冷沖壓模、拉伸模、搓絲模、冷沖裁模、沖頭號10、SM45——一般碳素塑料模具鋼（日本鋼號S45C）10、DCCr12MoV——耐磨鉻鋼國產(chǎn).較Cr12鋼含碳量低,且加入了Mo和V,碳化物不均勻有所改進,MO能減輕碳化物偏析并進步淬透性,V能細化晶粒添加耐性.此鋼有高淬透性,截面在400mm以下能夠徹底淬透,在300~400℃仍可堅持杰出的硬度和耐磨性,較Cr12有高的耐性,淬火時體積改變小,又有高的耐磨性和杰出的歸納機械功能.所以能夠制作截面大,形狀雜亂。對圓試件一般要放在V形槽中測試。</p><div

展開全部304不銹鋼材質硬度：≤187HB；≤90HRB；≤200HV。304不銹鋼是不銹鋼中常見的一種材質，密度為g/cm3，業(yè)內也叫做18/8不銹鋼。耐高溫800度，具有加工性能好，韌性高的特點，***使用于工業(yè)和家具裝飾行業(yè)和食品醫(yī)療行業(yè)。市場上常見的標示方法中有00Cr19Ni10，SUS304，其中00Cr19Ni10一般表示國標標準生產(chǎn)，一般表示ASTM標準生產(chǎn)，SUS304表示日標標準生產(chǎn)。304是一種通用性的不銹鋼，它***地用于制作要求良好綜合性能（耐腐蝕和成型性）的設備和機件。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有18%以上的鉻,8%以上的鎳含量。304不銹鋼是按照美國ASTM標準生產(chǎn)出來的不銹鋼的一個牌號。拓展資料：組成元素：在空氣中或化學腐蝕介質中能夠抵抗腐蝕的一種高合金鋼，不銹鋼是具有美觀的表面和耐腐蝕性能好，不必經(jīng)過鍍色等表面處理，而發(fā)揮不銹鋼所固有的表面性能,使用于多方面的鋼鐵的一種，通常稱為不銹鋼。代表性能的有13鉻鋼，18-8鉻鎳鋼等高合金鋼。不銹鋼防銹的機理是合金元素形成致密氧化膜，隔絕氧接觸，阻止繼續(xù)氧化。所以不銹鋼并不是“不銹”。304材料出現(xiàn)生銹現(xiàn)象，可能有以下幾個原因：1.使用環(huán)境中存在氯離子。氯離子***存在。金屬硬度測量**早由雷奧姆爾提出硬度定義，表示材料抵抗硬物體壓入其表面的能力。供應硬度機</p><p
