OEM鍛件的力學(xué)性能比鑄件好，能承受較大的沖擊力和其他重載荷。因此，凡是重要、受力大的部位都采用鍛件。對于碳化物含量高的鋼，OEM鍛件的質(zhì)量比軋制材料好

OEM鍛件的范圍是什么？

在鍛造中，可以對金屬毛坯施加壓力，使OEM鍛件產(chǎn)生塑性變形，改變其機械性能。通過(guò)鍛造可以消除金屬的疏松?？锥?，提高鍛件的機械性能。

缺陷通常由鍛造工藝不當引起

晶粒大通常是由于始鍛溫度高、變形程度不夠，或終鍛溫度高或變形程度落入臨界變形區所致。鋁合金變形過(guò)大，導致織構形成；高溫合金變形溫度過(guò)低時(shí)，混合變形組織的形成也會(huì )導致晶粒粗大。

常見(jiàn)鍛造方法及其優(yōu)缺點(diǎn)

自由鍛造是指利用簡(jiǎn)單的通用工具或直接在鍛造設備的上下砧之間施加外力，使毛坯變形，獲得所要求的幾何形狀和內在質(zhì)量的鍛件加工方法。采用自由鍛造方法生產(chǎn)的鍛件稱(chēng)為自由鍛件。

工程機械鍛件四種檢驗方法

工程機械鍛件需要根據產(chǎn)品的生產(chǎn)線(xiàn)滿(mǎn)足一定的要求，達到標準后才能投入使用，現在就讓小編給大家講講如何才能達到標準吧。一是生產(chǎn)工程中要由專(zhuān)門(mén)的人員按照相關(guān)標準進(jìn)行制造；

鍛造時(shí)需要注意什么？

對于變形難度較大的合金，應盡可能采用緩慢變形，控制每錘或壓力機每次行程的變形??量，一般在20%左右。對于速度敏感的材料，變形速度的選擇還應考慮河北溫州鐵路鍛件對整條鐵路質(zhì)量的影響。
