锻件的可锻性通常是在热状态下进行的，锻件的可锻性是金属在热状态下经受压力加工时塑形变形的过程。山东锻件厂对锻件的可锻性优劣常用金属的塑形和变形抗力两个指标来综合考虑。

　　The malleability of a forging is usually carried out in a hot state, and the malleability of the forging is the process of deforming the metal when it is subjected to pressure in the hot state. Shandong forging factory considers the two aspects of the forging quality, the metal forming and the deformation resistance.

　　那么影响锻件可锻性的因素首先是金属的成分，纯金属好于合金，低碳钢优于高碳钢，低碳钢合金钢优于高碳高合金钢;有害杂质元素一般使可锻性变坏。还有就是锻件使用金属的组织，单项组织好于多想组织;铸态下的柱状组织、粗晶粒组织、晶界上存在偏析、或有共结晶组织都会使锻件的可锻性变差。最后还应当考虑锻件厂的加工条件：

　　Then the influence factors of forging forging is the first metal component, better than pure metal alloy is better than that of low carbon steel, high carbon steel, low carbon alloy steel is better than that of high carbon high alloy steel; impurity elements generally make malleable bad. There is also the use of metal tissue in the forging, the single organization is better than the organization; the columnar structure, coarse grain structure, segregation on the grain boundary or eutectic structure will make the forging of forging become worse. Finally, the processing condition of the forging plant should be considered:

　　1、变形温度：一般随变形温度的升高，可提高金属的可锻性;当温度接近熔点时，会引起过烧，是可锻性急剧降低。

　　1, deformation temperature: generally with the increase of deformation temperature, can improve the malleability of metal; when the temperature close to melting point, will lead to over burning, is a sharp reduction in malleability.

　　2、变形速度：一方面随着变形速度的增加，回复与再结晶过程来不及进行，不能及时消除加工硬化现象，故使塑形降低，变形抗力增大，可锻性变差。另一方面随着变形速度的增高，产生热效应，是金属的塑形升高，变形抗力降低，又有利于改善可锻性。

　　2, deformation speed: on the one hand, with the increase in deformation rate, the recovery and recrystallization process is too late, and can not eliminate the work hardening phenomenon in time, so the molding reduces, the deformation resistance increases, and the malleability becomes worse. On the other hand, with the increase of the deformation rate, the thermal effect is caused by the increase of metal forming, the decrease of deformation resistance and the improvement of the malleability.

　　3、应力状态：拉应力成分数量愈多，要求锻件材料塑形愈好;压应力成分数量愈多，可降低对材料塑性的要求。

　　3, stress state: the number of tensile stress components, requiring the molding of the forging material is better; the number of compressive stress components, can reduce the plastic requirements of the material.
