标准范围

本文件规定了抗震改进结构用钢的质量。它适用于在可逆轧机上轧制的钢板、宽平板、热轧型材，这些钢板在轧制状态下使用，但SA440级除外，SA440级通常使用淬火和回火或热机械控制工艺生产，通常用于焊接或螺栓连接结构。本文件涵盖5种钢种和7种质量。SA235、SA325、SA345、SA390和SA440等级。不是所有等级都有所有品质，有些品质有夏比V？缺口要求。本文件规定的钢材适用于最小公称厚度为6？mm，最大公称厚度为150？mm的钢板，最大公称厚度为140？mm适用于宽平底鞋和热-轧制型材。本文件不包括以下结构钢，其中一些结构钢由其他国际标准涵盖:—？片材和带材，例如ISO 4995或ISO 4996；—？管状产品。例如ISO 12633-1、ISO 12633-2。笔记？除非另有说明，否则术语“厚度”被认为是“标称厚度”。

This document specifies qualities for steels for seismic-proof improved structural use. It is applicable to steel plates rolled on a reversing mill, wide flats, hot-rolled sections, which are used in the as-rolled condition, with the exception of grade SA440, which is normally produced using quenched and tempered or thermomechanical controlled process and normally intended for welded or bolted structures.

This document covers 5 steel grades and 7 qualities. Grades SA235, SA325, SA345, SA390 and SA440 are covered. Not all grades are available in all qualities, and some qualities have Charpy V？notch requirements.

The steels specified in this document are applicable to hot-rolled plates, wide flats, and sections with a minimum nominal thickness of 6 mm and a maximum nominal thickness of 150 mm for steel plates, and a maximum nominal thickness of 140 mm for wide flats and hot-rolled sections.

This document does not include the following structural steels, some of which are covered by other International Standards:

—     sheet and strip, e.g. ISO 4995 or ISO 4996;

—     tubular products. e.g. ISO 12633-1, ISO 12633-2.

NOTE            The term "thickness" is considered as "nominal thickness", unless otherwise stated.
