</p> <p> <br /> </p> <p> 美國(guó)熱軋模具鋼分二大類(lèi)：熱軋模具鋼，和超級(jí)熱強(qiáng)合金。 </p> <p> 熱軋模具由于在有溫度的條件下工作，要求材料具有熱強(qiáng)性和熱耐磨性，P20模具鋼定制，為了保證模具的使用壽命模具要冷卻，熱冷交替模具會(huì)出現(xiàn)龜裂，即熱疲勞裂紋，所以材料又要求有抗裂紋能力和抗熱疲勞性能。 </p> <p> 按熱強(qiáng)性排列的主系列進(jìn)行選材: </p> <p> 低合金調(diào)質(zhì)模具鋼（6G，6F2，6F3）→中鉻熱作模具鋼（H11、H12、H13）→鎢熱作模具鋼（H21，H22）。 </p> <p> 非標(biāo)準(zhǔn)的熱作模具鋼：例如熱鐓鍛模具用時(shí)效硬化型的6H4。使用H11、H12、H13出現(xiàn)了不能滿(mǎn)足熱耐磨性時(shí)，可以選擇6H1，P20模具鋼定制，6H2。 </p> <p> 當(dāng)要求模具以熱作耐磨性為主時(shí)，可以選擇D2，D4→M2，M4→粉末鋼，P20模具鋼定制。鋼結(jié)硬質(zhì)合金、鈷基硬質(zhì)合金的高溫耐磨性是很高的，但其熱疲勞性（即冷熱抗疲勞裂紋）很差，不能在急冷急熱狀態(tài)下使用。 </p> <p> <br /> </p> <p> <br />
