螺旋鋼管的退火方式介紹

螺旋鋼管的退火方式

1.球化退火

球化退火主要用于超共析碳素鋼和合金工具鋼(例如用于制造切削工具,量具和模具的鋼)。其主要目的是降低硬度,改善可加工性并為將來的硬化做準備。

2.應力消除退火

應力消除退火也稱為低溫退火(或高溫回火)。該退火主要用于消除鑄件,鍛件,焊接件,熱軋件,冷拔件等中的殘余應力。如果不消除這些應力,則在一定時期或期間內,鋼件將變形或破裂。隨后的切割過程。

3.完全退火和等溫退火

完全退火也稱為重結晶退火,通常稱為退火。該退火主要用于各種碳鋼和合金鋼的鑄造,鍛造和熱軋型材,包括:

次共析成分,有時也用于焊接結構。通常用作某些非重工件的最終熱處理,或用作某些工件的預熱處理。
