material selection:
Ferritic stainless steel became the material of choice for Auto exhaust gas pipes. 1) Ferritic stainless steel does not contain or less precious metal Ni, and the cost of raw materials is low; 2) ferritic stainless steel has a small thermal expansion coefficient, high thermal conductivity, good high-temperature oxidation resistance under repeated heating and cooling conditions, and has good 3) Compared with austenitic stainless steel, ferritic stainless steel has good resistance to chloride, stress corrosion and intergranular corrosion.
Through the above introduction and analysis of the material selection of the Auto exhaust gas pipe, hope it helps you.
