承压设备用5 mm超薄X7Ni9钢板叠轧工艺OACSTPCD

The technical requirements,process control points,and physical quality of the 5mm ultra-thin X7Ni9 steel plate produced by Wugang using the stacked rolling process were introduced.By reasonably controlling the composition of the billet,billet compositing,rolling,and heat treatment process,Wugang Company successfully produced 5mm ultra-thin X7Ni9 steel plates using the stacked rolling process.Both the thickness and unevenness of the stacked rolled steel plate can meet the requirements of EN 10029:2010"hot-rolled steel plate 3 mm thick or above-Tolerances on dimensions and shape".The steel plate has good performance,and there is a large margin of tensile performance from the standard value.The presence of reverse austenite in the microstructure ensures good low-temperature impact performance of the plate.
