摘　　要：为拓宽公司的品种钢结构,满足工程制造行业客户的要求,南阳汉冶特钢有限责任公司采用锭模浇铸、3 800 mm轧机轧制、正火热处理工艺成功地开发并批量生产了150 mm厚A633GrD低合金高强度结构钢板,屈服强度控制在340～370 MPa,抗拉强度控制在495～520 MPa,伸长率控制在25%～35%,冲击功控制在122～167 J,各项指标均满足A633GrD的开发要求。To broaden the steel variety of the company and meet customer requirements of the engineering and manufacturing sector, Nanyang Hanye Special Steel Co. , Ltd. has successfully developed and produced the 150 mm thick A633GrD low-alloy high strength structural steel in batch by way of ingot mold casting, 3 800 mm mill rolling and normalizing （heat treatment） process. The yield strength of the newly developed steel is controlled within the limit of 340-370 MPa, tensile strength in 495-520 MPa, elongation rate in 25% to 35 % and impact energy in the 122-167J, therefore all indicators are in conformity with the requirements of A633G-rD development.
