退火状态，钢材交货状态的一种，即钢材出厂前经退火热处理。将金属缓慢加热到一定温度，保持足够时间，然后以适宜速度冷却（通常是缓慢冷却，有时是控制冷却）的一种金属热处理工艺。
退火状态AR CAP合金的伸长率高达45%，这使得可以深冲。
In annealed temper ARCAP alloys have an elongation up to 45% which allows deep drawing.
结果表明：位错密度随变形量的增加而提高，退火状态时位错密度较低。
The results show that the increase of dislocation density is accompanied by the increase of deformation amount. The dislocation density has lower value when the steel is annealed.
结果表明，该钢退火状态存在四种类型碳化物，淬火组织以板条马氏作为主。
The results show that there are four kinds of carbides in annealed state of the steel, and major portion of quenched martensite is lath-like martensite.
