Do you not use stainless steel cars because of fear of long life?1. Stainless steel is heavier than steel and aluminum alloy, which will result in high fuel consumption?First of all, the density of stainless steel and ordinary steel is not much different. Now the density of Q235 cold-rolled steel is about 7.85kg/cm3, and the highest density of stainless steel is 317L stainless steel, density is 8.25kg/cm3, the weight of white body The proportion of whole vehicle is about 20%~30%, even if it is calculated as 300kg white body weight (in fact, stainless steel is not yet able to replace thermoformed steel in white body), the volume of steel used is also 300/7.85≈38 cm3, even if it is replaced completely. The added weight of stainless steel is 38 cm3 x (8.25 - 7.85) kg/cm3 ≈ 15 kg. This weight is completely negligible.430 grade 3x1000x2000mm square meter price stainless steel plateIn addition, the steel used in various parts of the bodywork is different, such as the hood and tailgate cover, which is light weight laminated steel plate, this steel plate has a good sound absorption and shock absorption capacity, if replaced by stainless steel plate The NVH of the vehicle cannot be guaranteed.High performance technology products 430 decorative stainless steel sheet2, stainless steel coating difficult?This reason is not valid. Now even carbon fiber and plastic can be coated, not to mention stainless steel? The self-media said that stainless steel can not be painted, it should be inspired by their own stainless steel doors and windows - stainless steel doors and windows can not be painted, mainly because the surface has been specially polished. Similarly, polished galvanized steel is also difficult to paint. However, not all stainless steel surfaces are mirror-like. So, don't talk to the general good or bad?304 espesor de pared delgada Tubo de acero inoxidable sin costuras3. As for the difficulty of stainless steel coating process, it will increase the coating cost... This is not true.In fact, because stainless steel does not require anti-corrosion treatment, it can greatly shorten the working hours and reduce the cost in the coating process. This is one of the main reasons why stainless steel becomes the mainstream material of subway car body – of course, another main reason will be described later.
