The invention discloses a high-hardness retractable door. The high-hardness retractable door consists of a door body, a driving motor, a sliding rail and a control system, wherein the door body is driven by the driving motor to move on the sliding rail, the control system is connected with the driving motor in a communicating manner, and the driving motor is controlled by the control system to operate; the door body is made from troostite high-chromium steel; the troostite high-chromium steel comprises the following components in percentage by weight: 1.8-2.4% of carbon, 9-12% of chromium, 0.7-1.2% of molybdenum, 0.5-1% of copper, 0.4-0.8% of manganese, 0.6-0.8% of silicon, sulfur of which the percentage by weight is smaller than or equal to 0.08%, phosphorus of which the percentage by weight is smaller than or equal to 0.05% and the balance Fe and inevitable impurities. The hardness and the abrasion resistant property of the high-hardness retractable door disclosed by the invention can be greatly improved, the strength of a product is greatly improved, and frictional loss between the door body and the sliding rail can be observably reduced.
