Driving on poorly-lit roads means that there are many precautions for driving at night. Many accompanying drivers also consistently report that it is difficult to drive, it is more difficult to drive in rainy days, and it is most difficult to drive at night. Why are there more precautions for driving at night? The main reason is that the nighttime light is poor, and sometimes it is affected by the opposite and rear vehicle lights, resulting in a narrow field of view, and the pre-judgment is relatively late, so it is more prone to dangerous situations.
Driving on poorly lit roads requires attention to the following matters
Driving at night is slow
Ten accidents were nine times slow, but this is the truth that has never changed. When driving at night, the light is much worse than the daytime. The streetlights can only look at the small area below the streetlights, and the lights can only see the front. The mopeds and pedestrians on the roadside can only look vaguely. A little bit. If you encounter an unexpected situation, it is difficult to respond quickly. Therefore, in the night driving notice, the slow speed is the first.
Driving at night is the most difficult driving
Fatigue driving is no less light than drunk driving, especially for long-distance driving. Be sure to prevent fatigue driving. When driving at night, because of the influence of people's work habits, the spirit is definitely a lot worse than the daytime. If you drive in the middle of the night, it is easier to make people sleepy. Therefore, when driving at night, if you feel that your spirit is not very good, you must stop and rest, do not fatigue driving.
Drive at night and pay close attention to the warnings ahead
Because obstacles can appear at any time on the road, such as stones, branches, or items falling from the front. This is an important part of the night driving notice. Because the driving line at night is not clear, it is easy to ignore the situation on both sides of the road and the front, so when driving at night, don't take it lightly.
The most important thing to drive at night: Be careful when overtaking
When you overtake at night, you should have more observations than during the day to ensure that all parties have no vehicles to change lanes to avoid danger. We must remember that when driving at night, not only our own sight is not good, other car owners are not good at sight, so we must consider the feelings of other car owners, can not make too sudden movements, or else, Other car owners do not react, it is very easy to be dangerous.
Driving at night, it is very important when driving
Driving at night is easy to touch someone else to flash you with a high beam, sometimes reminding you that it is too slow, sometimes reminding you to take his path. If you encounter someone else flashing your situation, you should observe whether it is illegal. If not, then don't worry. If you press the line yourself, pay attention to even correction. If you have a high beam in a place where there is no street light, there is a vehicle coming in front of you. When you want to get a car, you must switch to a low beam.
DUPLEX STAINLESS STEEL
Duplex Stainless Steels Available
Yuhong Group supplies LDX2101, 2205, Ferralium 255, Zeron 100 and LDX2507 in the form of plate, sheet, strip, bar, pipe, tubing, pipe fittings, flanges and weld wire.
Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Lean Duplex such as LDX2101
Standard Duplex such as 2205, the work-horse grade accounting for more than 80% of duplex usage
Super Duplex such as Ferralium 255 and Zeron 100 and LDX2507
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
