Stainless steel composite plate with interface shear strength of 400MPa for plateau environment bridge and preparation method of stainless steel composite plate
The invention relates to a stainless steel composite plate with interface shear strength of 400MPa for a bridge in a plateau environment and a preparation method of the stainless steel composite plate, and belongs to the technical field of composite plates. The composite plate comprises austenitic stainless steel and low-carbon bainite type weathering resistant steel, the austenitic stainless steel is a composite layer, the low-carbon bainite type weathering resistant steel is a base layer, and the interfacial shear strength is larger than or equal to 400 MPa. The low-carbon bainite weathering resistant steel is used as a base layer, the weathering resistant index is larger than 6.2, and the high-altitude atmosphere corrosion environment can be adapted. Austenitic stainless steel is used as a composite layer, corrosion of accumulated water or corrosive solution at the joint of the railway ballast and the bridge deck to the bridge deck structure is prevented, and the defect of corrosion resistance of weathering steel is overcome. Meanwhile, compared with all stainless steel, the cost is reduced.
本发明涉及一种高原环境桥梁用界面剪切强度400MPa级不锈钢复合板及其制备方法，属于复合板技术领域。所述复合板包括奥氏体型不锈钢与低碳贝氏体型耐候钢，其中所述奥氏体型不锈钢为复层，所述低碳贝氏体型耐候钢为基层，界面剪切强度≥400MPa。以低碳贝氏体型耐候钢作为基层，其耐候指数＞6.2，可以适应高原大气腐蚀环境。以奥氏体型不锈钢作为复层，阻止了道砟与桥面连接处积水或腐蚀溶液对桥面结构的侵蚀，弥补耐候钢腐蚀性能的不足；同时相比全不锈钢，降低了成本。
