Over the past decade, Japanese car consumption has risen from 10 kilograms to 30 kilograms, and the United States has more than 40 kilograms. Mass transit vehicles such as buses, subways and high-speed trains have also been widely adopted in stainless steel. China's cities in Shanghai, guangzhou, wuhan and chongqing use aluminum alloy cars. Tianjin binhai fast track transportation USES stainless steel car; Beijing hosted the 2008 Olympic Games, mainly using stainless steel cars. The qinghai-tibet railway considers the use of stainless steel railway buses. At the end of 2010, the Beijing subway line 15 will adopt the first domestically developed stainless steel subway vehicle products, and the total number of cars will be up to 15, with two of them listed as a complete standby vehicle. In 2011, China successfully manufactured the important parts of railway buses with double phase stainless steel and replaced imported products, which have been successfully used in metro vehicles. The demand for light weight and high gear development of track vehicles will be the main development direction of future rail cars.

Xin bin Thai stainless steel not only have corrosion resistance, and good physical properties and surface quality, widely used in automobile manufacturing, the current application components mainly has the following categories.

The exhaust system is stainless steel: mostly ferritic stainless steel, which is the most applied component of automobile stainless steel. 409L, 436L are all commonly used stainless steel. From the point of view of economy and practicability, and some European and American countries of auto exhaust system often choose type 0 cr11ti ferritic stainless steel, Japan is basically adopts the 13 cr - 17 cr ferritic stainless steel and its modified.

2, automobile fuel tank with stainless steel: made of stainless steel fuel tank in addition there is no risk of leakage of fuel, and has excellent corrosion resistance and good forming performance, and can save or simplify the coating process, and easy to recycle. 304L, jfe-sx1, etc. Are commonly used stainless steel.

3, with stainless steel chassis frame: combined chassis frame design combined with stainless steel materials of excellent properties, it can make the produce better car impact resistance, light weight, high safety and reliability and long service life, in addition, the frame can be completely recycled. 409L, 3Cr12, 304L are all commonly used stainless steel.

4, auto parts: stainless steel are mainly stainless steel sealing and heat exchanger, seal ring generally adopts 301 stainless steel, heat exchanger generally use SUS304, SUS409L and SUS430 stainless steel material; The cr-ni austenitic stainless steel is also used on some parts. 0Cr17, 0Cr18Ni9 for oil cooler plate heat exchanger; The type 0Cr17 can be used for headlights, large passenger rail, safety railings and so on.

5, automotive decorative stainless steel: small cars with stainless steel strip, antenna, wheel cover, etc., on the handrail of a large passenger cars, vehicles, safety railing, hanging on the hand lever is stainless steel. In order to reduce the cost, the rearview mirror is mainly used by SUS430J1L, which is stainless steel, and the rear-view mirror of some high-grade cars is made of SUS436J1L stainless steel. The car windshield wipers use SUS430, SUS304, SUS301, etc. The headlamp ring adopts steel such as SUS430. Safety devices on cars also often use stainless steel. For example, the seat belt tightening device USES SUS301 stainless steel, the sensor and booster pump of the airbag are mainly used by SUS304 and SUS304L stainless steel, and the ABS ring is used for steel such as SUS434 and SUS444.

Automobile frame or car casing: a stainless steel car frame, made of stainless steel, with 11 percent to 12 percent Cr, and the overall hull of the car, which is commonly used in the number 00Cr11Ti, 0Cr11Ni4Ti, 00Cr12NiTi, etc. Some countries have already used stainless steel in large buses, coal trucks and city subway vehicles.

The automotive industry is the fastest growing stainless steel application. Public transport vehicles such as buses, subways and high-speed trains are widely used in stainless steel. To increase market demand for high-grade car, considering the cost of manufacture, maintenance and energy consumption, stainless steel car significantly lower than that of aluminum alloy and carbon steel models, so the stainless steel car is the most economical vehicles, has great prospects for development, made of stainless steel used in automobile manufacturing industry showed a trend of worldwide expansion, has great potential market.
