Audited Supplier Zhengde Automobile exhaust pipes include straight pipes, perforated pipes, large pipes, bent pipes, spinning parts, stamping parts, welded assembly, etc.
The main types of welded steel pipes for automobiles include automobile transmission shaft pipes, automobile muffler pipes, automobile condenser pipes, automobile exhaust pipes, automobile control shaft pipes, automobile thrust pipes, automobile shock absorber oil storage pipes, etc. Seamless steel pipe for automobile axle casing (GB3088-82) is a high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe used in manufacturing automobile axle casings and drive axle housing axle tubes.
Stainless steel welded pipes are most commonly used in the automobile industry in exhaust systems, accounting for more than 1/2 of the total stainless steel consumption in automobiles, and 80% are ferritic stainless steel. The exhaust gas generated by the car engine passes through the exhaust air intake pipe, front pipe, hose, converter, center pipe and finally flows out of the muffler. Generally, 409L, 439M, and 436L materials are used to produce exhaust pipes. They are characterized by good corrosion resistance under high temperature and good strength under high temperature conditions. They are also clean and environmentally friendly. They are the most commonly used exhaust pipe materials in the automotive industry. , has been recognized in the industry. According to estimates, the stainless steel pipes used in automobiles account for about 1.5% of the total consumption of stainless steel pipes by downstream users, and the usage ratio of stainless steel seamless pipes and welded pipes is about 2:1. Each car uses stainless steel welded pipes between 24 and 30kg, which are mainly used in three-no purifiers and exhaust pipes.
Stainless steel used in exhaust systems in the automobile manufacturing industry is T409, T439, AL409, 436S, etc. As the service conditions of the exhaust system become more severe and the exhaust temperature rises to 950°C~1000°C, the stainless steel used for the exhaust manifold has progressed from SUH409L (low grade) and SUS430JIL (high grade) to the high-performance material SUS444. The temperature of the muffler system can reach 300°C, and the materials used have similar changes. Due to increasingly fierce market competition, low-cost materials have become a new development direction.
