The invention relates to a ventilation box applied to a cabin and belongs to the technical field of ventilation devices. The ventilation box comprises a box body and a plurality of air guide plate units; an air inlet is formed in one side of the box body; an air outlet is formed in the other side of the box body; air guide channels for passing of the airflow are formed in each air guide plate unit; the air guide channels are communicated with the air inlet and the air outlet respectively; the air guide plates are made of stainless steel; the stainless steel comprises the following components in percentage by mass: 0.03-0.06% of carbon, 18.5-22.5% of chromium, 12-16% of nickel, 1.2-1.5% of silicon, 0.8-1.5% of manganese, 2-3% of molybdenum, 2.2-2.6% of copper, 0.1-0.5% of titanium, smaller than or equal to 0.035% of phosphorus, smaller than or equal to 0.030% of sulphur and the balance of iron. The ventilation box is reasonable in structurally design; the air guide plates excellent in mechanical performance are made of austenitic stainless steel; the excellent ventilation performance of the cabin is ensured; the ventilation performance and the waterproof performance of the cabin are further improved; the service life of the cabin is further prolonged.
