6.1.2钢板及钢带的成品化学成分允许偏差应符合GB/T 222的规定。
6.2 冶炼方法
<*n>钢板及钢带所用的钢采用氧气转炉冶炼。*n>
6.3 交货状态
6.3.1钢板及钢带冷连轧后经退火及平整后交货。
6.3.2钢板及钢带通常涂油供货,所涂油膜应能用碱水溶液去除。在通常的包装、运输、装卸和储存条件下,供方应保证自制造完成之日起6个月内,钢板及钢带表面不生锈。根据需方要求,经供需双方协议并在合同中注明,亦可以不涂油供货。
6.4 力学性能
6.4.1对于牌号为DC01的钢板及钢带,其力学性能的有效期不作保证;对于牌号为DC03、DC04、DC05、DC06和DC07的钢板及钢带,应保证在制造完成之日起6个月内,钢板及钢带的力学性能符合表5的规定。
6.4.2 由于时效的影响,钢板及钢带的力学性能会随着储存时间的延长而变差,如屈服强度和*拉强度的上升,断后伸长率的下降,成形性能变差、出现拉伸应变痕等,建议用户尽早使用。
