Description

类似钢材等级:

化学成分:

基本介绍:

A2钢是美国高韧性耐磨工具钢,属风淬钢。该钢含碳质量分数约1%,热处理后硬度可达57~62HRC,铬质量分数约5%,经磨削后钢材表面光泽较深,耐蚀性优良,延展性很强,模具刃口的耐磨性好。该钢淬透性好,碳化物分布均匀,有一定的冲击韧性和良好的耐磨性。具有良好的空淬性能,空淬后尺寸变形小,碳化物均匀细小,耐磨性好。

特征:

1.拉伸模、卷边模、压花模。2
.切削刀具。3
.用于热固性塑料模具和整体硬化模具。

热处理:

A2钢坯再锻,加热温度1130~1100℃,开锻温度1050~1100℃,终锻温度850~900℃。由于钢的空冷淬硬性好,锻后应注意缓冷。退火温度为840~860℃,等温温度为740~760℃,退火后硬度为202~229HB。
