With high fatigue limit, the hardenability is higher than that of 40Cr steel. The critical hardenable diameter in oil is 16-78mm. The steel has high creep strength and long-lasting strength at high temperature. The long-term working temperature of steel can reach 500. °C; This steel has good low temperature toughness and can work at -110 °C. This kind of steel belongs to fine-grain steel. It has no tendency to overheat when heat treatment, and has small quenching deformation, but it has the first type of temper brittleness; the machinability of steel is acceptable, the plasticity is moderate during cold deformation, and the weldability is poor. It needs to be preheated to 150. It can be welded after ~400 °C, and stress relief treatment should be carried out after welding. This kind of steel is usually used as a tempering part. It can also be used after high-intermediate frequency surface quenching or quenching and low and medium temperature tempering. It is suitable for important structural parts working under high load, especially shock, vibration, bending and torsional load. Parts such as axles, engine transmissions, large motor shafts, turbine engine spindles, rolling mill herringbone gears, crankshafts, hammers, connecting rods, fasteners, and perforators in the petroleum industry; It is used to manufacture bolts with working temperature below 400 °C, nuts below 510 °C, thick wall seamless high pressure for working in non-corrosive medium in chemical equipment with working temperature of 450-500 °C. catheter. In addition, this steel can also be used to replace large-section gears and high-load transmission shafts, turbine generator rotors, and support shafts with a diameter of less than 500 mm instead of 40CrNi steel. Good low temperature toughness, high durability and creep strength at high temperature, working temperature up to 500 ° C, low temperature to -110 ° C, high strength, impact toughness and high fatigue strength, good hardenability, The quenching deformation is small, the cutting performance is medium, and the weldability is poor. It can be used after general quenching and tempering treatment, and can also be used after high and medium frequency surface quenching or quenching after low and medium temperature tempering.

Parking lot lighting is the lighting equipment and program installed in the parking lot. Parking lot lighting is designed to provide enough light to ensure the safety of parking lot users and to ensure that they can clearly see vehicles, pedestrians and other obstacles.
The importance of parking garage lighting cannot be ignored. First, proper security lighting can improve the safety of parking lots. Bright outdoor lighting reduces crime and makes people feel safer. Secondly, good area lighting can improve the availability and convenience of parking lots. Clearly visible markings and road signs, as well as proper lighting, make it easy to find parking and navigate to your destination.
LED lighting technology is widely used in exterior lighting. LED lamps have the advantages of high brightness, energy saving, environmental protection and long life. They are able to provide uniform and bright lighting at lower energy consumption, reducing energy consumption and maintenance costs. In addition, the intelligent control system can realize functions such as time control, dimming and motion sensing, which can be flexibly adjusted as needed to further improve energy efficiency.
Through reasonable planning and application of parking lot lighting scheme, the visibility, safety and comfort of parking lot can be improved. The proper lighting design should consider the size of the parking lot, the layout, the density of the parking space, and the surrounding environment. The right lighting solution can increase confidence in the parking lot, enhance the user experience, and facilitate traffic flow and management.Outdoor Lighting,Area Lighting, Parking Garage Lighting, Exterior Lighting, Security Lighting
