[3]。其屈服強(qiáng)度約730MPa，抗拉強(qiáng)度約760MPa，延伸率達(dá)25%，兼具優(yōu)良冷彎、焊接及抗沖擊性能，符合歐洲EN10149-2標(biāo)準(zhǔn)S700MC等級(jí)和日本JIS標(biāo)準(zhǔn)Wel-ten80級(jí)別，國(guó)產(chǎn)同級(jí)別替代材料包括太鋼T700鋼。主要應(yīng)用于工程機(jī)械吊臂、汽車結(jié)構(gòu)件、橋梁及船舶組件等領(lǐng)域 [1]。該鋼種采用鈮、釩、鈦等微合金成分體系，通過(guò)析出強(qiáng)化與細(xì)晶強(qiáng)化工藝實(shí)現(xiàn)強(qiáng)度與塑性的平衡 [2]。生產(chǎn)流程包括板坯加熱、軋制、層流冷卻等工序，厚度范圍涵蓋2.0-20.0mm，常規(guī)寬度為1250-1500mm。熱軋工藝使其具備優(yōu)于冷軋鋼板的延展性和加工適應(yīng)性，但表面存在氧化層且強(qiáng)度略低。焊接時(shí)需控制熱輸入量并適配氣體保護(hù)焊、電弧焊等方法。中文名V 釩≤0.20P
