GB/T6725-2008冷弯型钢
本标准规定了冷弯型钢的订货内容、分类和代号、尺寸、外形、重量及允许偏差、技术要求、试验方法、验收规则、包装、标志和质量证明书。本标准适用于冷加工变形的冷轧或热轧钢板和钢带在连续辊式冷弯机组上生产的冷弯型钢。它是一份统一冷弯型钢技术条件标准,需要说明有如下几条
(1)冷弯型钢所采用的钢的牌号的化学成分制造冷弯型钢牌号和钢号,通常有以下几个
GB/T 699
优质碳素结构钢
代表钢号10钢20钢45钢
GB/T 700
碳素结构钢
代表钢号Q215Q235
GB/T1591
低合金高强度结构钢代表钢号Q345
GB/T4171耐候结构钢
代表钢号09 CuRE
GB/T3280
不锈钢冷轧钢板和钢带代表钢号Crl8Ni9
根据需方要求,345、390强度级别可使用细晶粒钢生产。如提出用其他牌号钢号生产冷弯型钢的,可以向生产企业提出。国外也有更高强度钢种制造冷弯型钢,如澳大利亚、新西兰用屈服强度等级在450MPa制造C形型钢和Z形型钢作厂房檩条,厚度仅1.5~2mm,美国用抗拉强度900MPa的钢种制造小轿车的保险杠,我国也在研制这些型材。
