style="text-indent:25px">圓鋼的淬透性和淬硬性：淬透性主要取決于圓鋼的化學(xué)成分和淬火前的原始組織狀態(tài)；淬硬性則主要取決于鋼中的含碳量。對于大部分的冷作模具鋼，淬硬性往往是主要的考慮因素之一。對于熱作模具鋼和塑料模具鋼，一般模具尺寸較大，尤其是制造大型模具，其淬透性更為重要。另外，對于形狀復(fù)雜容易產(chǎn)生熱處理變形的各種模具，為了減少淬火變形，往往盡可能采用冷卻能力較弱的淬火介質(zhì)，如空冷、油冷或鹽浴冷卻，為了得到要求的硬度和淬硬層深度，就需要采用淬透性較好的模具鋼。合金圓鋼適合大批量生產(chǎn)。威海440b圓鋼</p><p
