The car manufacturing process of each car company is different, the quality of the car is also different, some car companies do not pass the car manufacturing process, and the car made is easy to rust. In order to solve the problem of car rust, many car companies have come up with some ways, Porsche once made a bold decision, since stainless steel will not rust, why not use stainless steel to build cars?
Porsche's designers turned this idea into a reality, and in the 1960s Porsche developed a stainless steel car, which Porsche wanted to open up new markets with, but did not expect sales to be extremely unoptimistic.
In the 1960s, Porsche built a Porsche 911 out of stainless steel, although this car does not rust, but has other problems, the vehicle is difficult to drive on the road normally, but also has a great safety hazard. In the end, Porsche made of stainless steel cars became the laughing stock of the world, and this stainless steel 911 was not wanted, and finally it could only be displayed in the museum.
Disadvantages of stainless steel car:
Although stainless steel does not rust and has a hard texture, the ductility of this material is relatively poor, and it is not beneficial to use it to build a car. Nowadays, many car companies use some materials that are easy to deform in order to protect pedestrians, and some car companies also use pedestrian protection devices.
Stainless steel is very hard, made of stainless steel cars, after the collision of the vehicle can not be deformed to alleviate the impact force, will cause serious damage to the people in the car. One agency did a test to crash test stainless steel cars, and the passengers in the car were very badly injured.
The second disadvantage of stainless steel cars is that they cannot be built into the desired shape. Car companies will produce in a unified mold when they make cars, because the material of stainless steel is relatively special and not easy to polish, so car companies also need to customize a new set of molds, which is not only a waste of time, but also very troublesome.
The third disadvantage of stainless steel car manufacturing is that the car is not beautiful, the stainless steel material has a smooth appearance, and it is difficult to spray the car surface after making a car with stainless steel. Although the stainless steel 911 made by Porsche is high in appearance, the surface of the car cannot be repainted twice, and the car can only show the true background color of stainless steel.
The last disadvantage of stainless steel is that the weight is not up to standard. In order to speed up the speed of supercars, supercars often use weight reduction, stainless steel is relatively heavy, and the 911 made of stainless steel exceeds the standard. Porsche's stainless steel 911 weighs more than 100 kilograms more than the regular version, leading to an increase in fuel consumption.
Editor's Comments:
Many people only see the characteristics of stainless steel not rusting, they want to use stainless steel to build cars, these people completely ignore the shortcomings of stainless steel. In fact, stainless steel is not always rusty, stainless steel material lack of care, in the special environment is also easy to rust, the use of stainless steel to build a car is not realistic. After more than 100 years of development, the performance of the car is gradually stable, and changing the body material is a risky approach that is easy to fail.
Porsche, as a pioneer in the automotive industry, proposed that it is very creative to build cars from stainless steel, but engineers did not take into account the shortcomings of stainless steel, and it is only possible to fail to build a car. Now many car companies are improving the spraying process, by spraying paint on the surface of the car to do anti-rust treatment, the car has rarely rusted, stainless steel cars have finally become a thing of the past.
