低碳Mn-Si-Cr系F/B复相钢可能为大焊接线能量用钢

Low Carbon Mn-Si-Cr Ferritic/bainitic Steels Can Become Steels Used for High Welding Heating Input

试验结果表明,JB800钢具有可用大线能量焊接的特点。根据对此结果的原因分析,本文认为:研制低碳Mn-Si-Cr系F/B(或M/B)复相钢是发展高强度大焊接线能量用钢的新途径。

The experimental results prove that the steel JB800 can be welded with the high heating input.According to analyze to the reason of this results,this paper thinks:Making the steel of low carbon Mn-Si-Cr system and F/B(or M/B)duplex phases is a new path developing the high strength steels used for high welding heating input.
