Within the automotive high performance, lightweight course of, to fulfill the stringent requirements of automobile exhaust emission requirements, from the late 20th century, using stainless steel in automotive exhaust programs. America in the 1960s has begun to iron-chromium stainless steel for titanium exhaust system.

Japan can also be 70 years to exhaust customary requirements. The automobile manufacturers to extend three-way catalytic device in a automobile exhaust system to scrub exhaust emissions. Within the late 1980s, the Japanese government also on the life of an automotive exhaust system makes provision, thereby speeding up the promotion of ferritic stainless steel purposes. Currently in Europe, the United States and Japan automobiles, automobile exhaust system has been 100% stainless steel, especially in recent years, to meet the rising exhaust temperature, using excessive temperature, corrosion-resistant stainless steel as a substitute of aluminum castings and Pipe has been a carmaker's extensively used. Early, Japan, the United States, Europe and other broadly used stainless steel automotive exhaust systems, the main materials is 304 stainless steel.
Automotive exhaust system from the facet close to the engine starts, the exhaust manifold, front pipe, flexible pipe, catalytic converter, the center pipe, muffler and tailpipe and the like. Being dependent on the form of the automotive, and some also put in a number of catalytic converters and vice muffler. Automotive exhaust system with stainless steel due to its location is totally different. The performance necessities of the material differ. In the tube manifold and the other finish of the excessive temperature, for the reason that components directly related to the engine, so the excessive temperature performance, corresponding to excessive-temperature fatigue properties, thermal fatigue, high temperature oxidation and other necessities. At the identical time, seamless steel tube forming a posh manifold due to the material forming course of efficiency can be put forward higher requirements.

Automotive exhaust system catalytic converters bear ternary catalyst, their efficient catalysis happens ambient temperature exceeds 1000, so the catalytic converter used for a similar materials of the housing is required to have good high temperature oxidation. Meanwhile, resulting from the situation of the catalytic converter is straightforward to contact with the skin world, especially in coastal areas and snowmelt used cars, the catalytic converter housing is also vulnerable to the corrosive effects of salt corrosion of high temperature, excessive temperature salt corrosion properties of the fabric is very important. For pipe-in-pipe and muffler before connecting, using temperature at about 600, the primary failure is high temperature salt harm. Muffler exhaust system is a crucial a part of its materials failure is primarily condensate corrosion failure.
Stainless steel welded pipe production which we will select the suitable pipe processing methodology in line with the kind of pipe materials, pipe wall thickness and circumstances of use. Automotive Exhaust System pipe for pipe expansion when the elbow and higher processing requirements, in addition to the pipe material itself has greater necessities, and additional enhance the standard of the welded seam can be very important. Automotive Exhaust System ferritic stainless steel welded pipe production, from weld high quality to contemplate. Laser welding is the very best technique, excessive-frequency welding of the highest productiveness. Application of laser welding expertise, can ferrite grain growth HAZ harm lowered to a minimal, ensure that there is ample heat affected zone toughness, chilly deformation meets the requirements of the exhaust pipe.
