摘　　要：研究了奥氏体不锈钢与桥梁结构钢组合的321-Q370q复合钢板的性能。研究结果表明:321-Q370q复合钢板在保持了Q370q钢原有较高的强度和韧塑性以及良好的焊接性、疲劳性能的同时,兼具了321不锈钢良好的耐蚀性,能够满足GB/T8165-1997《不锈钢复合钢板和钢带》、GB/T714-2000《桥梁用结构钢》和TB10002·2-2005《铁路桥梁钢结构设计规范》、GB/T3280-1992《不锈钢冷轧钢板》、GB/T4237-1992《不锈钢热轧钢板》标准的规定,用于铁路桥梁的桥面板结构是安全可靠的。The performance of 321 - Q370q clad steel plate made of austenite stainless steel and bridge structural steel is investigated. The results indicated that the clad steel plate has both high strength , strong toughness and plasticity , good weldability and fatigue performance of Q370q steel and good corrosion resistances of 321 stainless steel, satisfy the requirements in standards including GB/T 8165 -- 1997 ColdRolled stainless Steel Sheets and P lates , GB/T 714--2000 Structural Steel for Bridge, TB 10002.2--2005 Code for Design on Steel Stucture of Railway Bridge, GB/T 3280--1992 Cold Rolled Stainless Steel Sheets and Plates ,GB/T 4237--1992 Hot Rolled Stainless Steel Sheets and Plates, which indicate that it is safe and reliable as floorboard of railway bridge structure.
