结构质量和高强度钢的热轧双辊铸轧钢板

[中文适用范围]： 本标准规定了结构质量热轧双辊铸钢板和高强度钢的要求。 该产品适用于需要特定机械性能的应用。 它通常在交付状态下使用，适用于螺栓、铆接或焊接结构，并且是在宽带钢轧机上生产的，而不是在板材轧机上生产的。 结构优质双辊铸钢板是一种按指定机械性能生产的碳钢，有多种牌号可供选择。 采用微合金强化的高强度热轧双辊铸钢板可达到指定的机械性能，并有多种牌号和类别可供选择。 [外文原描述]： This document specifies the requirements for hot-rolled twin-roll cast steel sheet of structural quality and high strength steel. The product is intended for applications where specific mechanical properties are required. It is generally used in the delivered condition and is intended for bolted, riveted or welded structures, and it is produced on a wide strip mill, not a plate mill. Structural quality twin-roll cast steel sheet is a carbon steel produced to specified mechanical properties and is available in a number of grades. High strength hot-rolled twin-roll cast steel sheet, strengthened by microalloys is produced to specified mechanical properties and is available in a number of grades and classes.
