                  其质量呆呆好坏问题一直是重点关注问题,据分析,卸扣的质量主要决定于淬火硬度、调质硬度等力学性能,神力□卸扣有D型卸扣和弓弱水形卸扣之分,材质皆为优质合金钢20Cr锻造制作。卸扣的工『艺主要为锻热淬火,锻热淬火是一项奥氏体化温度较高的最典型高温形变热处理工∮艺,可显著提高钢材强韧度,尤其是低温冲击韧度,详情如下:
                  具有形变强化和热处理强化的双重效果;锻热淬火可 呼以促使钢材冷却速度降低,锻热淬火是利用锻件余热直接淬火。从而提高整体卸扣的淬透性;锻热淬火的回火你要挑戰哪一個稳定性可以有效减小应力,提高钢材枯瘦老者緩緩說道韧性;中小规格钢制卸扣经锻热淬火并高温回火后,能间接性延长卸扣寿命。
