Precision Hot-Forging Dies for Motorcycle Crankshaft

45Cr2NiMoVSi钢制摩托车热锻模,经锻热调质预处理代替锻后球化退火及热锻模型面渗硼与淬火加热后,均达到节电、节时,简化工序及提高产品品质之目的;经综合热处理可使热锻模型面具有高硬度、高耐磨、高红硬性和抗疲劳、抗擦伤、抗氧化、抗腐蚀、抗粘结和表硬内韧充分发挥钢材之潜力。

45Cr2NiMoVSi steel hot-forging die is ideal in saving electricity,cutting time,simplifying processes and improving quality when used for crankshaft after the modified pre-treatment (instead of spheroidal annealing post forged) with the forging die borided and quenched, which makes the die surface possess high hardness as well as the resistance for fatigue, scoring, oxidizing, corroding, adhering with hard outside and tough inside obtained.
