2、实施之日起代替GB/T 11263-2005热轧H型钢和剖分型钢。本标准与GB/T11263-2005相比主要变化如下：增加H450150、H475150、H500150、H625200四个系列型号和H300200系列的H298201914规格。增加HP系列及厚度尺寸要求调整截面面积、理论重量及截面特性参数等数值。H型钢的尺寸、外形允许偏差中新增翼缘弯曲和翼缘腿端外缘钝化要求。取消了原附录A热轧H型钢常用钢种牌号及力学性能,附录A改为协议性超厚超重H型钢截面尺寸、截面面积、理论重量及截面特性（参考标准ASTM A6/A6M-2004）。新增附录B- 协议性H型钢尺寸、外形允许偏差（参考标准JI

3、S 3192-2008）。新增附录C- H型钢和H型钢桩的清理和焊补附录D中更新了新增加的工字钢与H型钢型号及截面特性参数对比。本标准与JISG3192-2008相比主要差异为：本标准修改采用了JISG3192-2008中与H型钢有关的内容。按宽翼缘、中翼缘、窄翼缘、薄壁将H型钢分为四个类别。增加薄壁类19个型号。增加H450150、H475150、H500150、H550200、H550300、H625200、H650300、H750300、H850300及H1000300十个系列型号和其它19个规格。增加部分剖分T型钢型号系列。增加-HP系列（表2）及H型钢桩尺寸允许偏差（表5）。表4中，

4、厚度t1增加“小于5mm ”一栏，其允许偏差0.5mm；厚度t2增加“小于5 mm”一栏，其允许偏差0.7mm；新增翼缘腿端外缘钝化要求。增加技术要求、试验方法、检验规则、包装、标志、质量证明书的规定。增加附录A：超厚超重H型钢截面尺寸、截面面积、理论重量及截面特性。增加附录B：H型钢尺寸、外形允许偏差（参考标准JIS 3192-2008）增加附录C：H型钢的清理和焊补增加附录D：工字钢与H型钢型号及截面特性参数对比。本标准附录、附录B、附录C和附录D为资料性附录。本标准由中国钢铁工业协会提出。本标准由全国钢标准化技术委员会归口。本标准起草单位：本标准主要起草人：本标准1989年2月首次发布，

5、1998年5月第一此修订，2005年5月第二次修订。热轧H型钢和剖分T型钢1 范围本标准规定了热轧H型钢和由热轧H型钢剖分的T型钢尺寸、外形、重量及允许偏差、技术要求、试验方法、检验规则、包装、标志、质量证明书。本标准适用于热轧H型钢（以下简称H型钢）、热轧H型钢桩（以下简称H型钢桩）和由热轧H型钢剖分的T型钢。2 规范性引用文件下列文件中的条款通过本标准引用而成为本标准的条款。凡是注日期的引用文件，其随后所有的修改单（不包括勘误的内容）或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本标准。GB/T 222
