屈服强度700MPa高强度低合金汽车钢板研发进展
|
摘要
全面梳理了国内外生产屈服强度700 MPa高强度低合金钢板的相关规范,系统调查了大量文献资料中相关研究动态,对比分析了不同厂家及材料牌号的工艺技术特点。研究表明:国内外绝大多数钢厂意识到了Nb、V、Ti、Ni、Cr、Mo、B等单元素微合金化对屈服强度700 MPa高强度低合金钢板性能的影响显著,其在提高强度、韧性、抗冲击性、塑性、焊接性等性能的同时,明显降低生产成本,在商用车轻量化方面具有显著优势。今后国内外研发的高强度低合金钢板仍主要以单一元素微合金钢为主,尤其是以铌微合金化和钛微合金化为主要发展趋势。
The related specifications for producing 700 MPa high strength and low alloy steel plates in China and other countries were comprehensively reviewed. The related research trends in a large number of literature materials were systematically investigated and the technological characteristics of different manufacturers and materials were compared and analyzed. The results show that most steel mills in China and other countries are aware of the significant effect of single element microalloying such as Nb, V, Ti, Ni, Cr, Mo, B on the properties of high strength low alloy steel sheets with yield strength of 700 MPa. It can improve the strength, toughness, impact resistance, plasticity, weldability and other properties, at the same time, it can obviously reduce the production cost, and it has remarkable advantage in the light-weight aspect of the commercial vehicle. In the future, the high strength low alloy steel sheet developed in China and other countries is still dominated by single element microalloyed steel, especially niobium microalloyed and titanium microalloyed steels as the main development trend.
