Stainless steel are magnetic like carbon steel. They are problematic to weld due to grain growth in the heat affected zone which reduces ductility and may result in cracks. Increasing chromium and molybdenum contents increase corrosion resistance as it does for austenitic stainless steels, however, this high alloying results in the precipitation of embrittling intermetallic phase upon welding. These microstructural problems due to welding restrict the use of ferritic stainless steels to very thin thicknesses and thus are not used in the construction of large heavy walled vessels and tanks, and structures like austenitic stainless steels. Common ferritic grades are: Type AISI
Braided stainless steel brake lines it is reasonable to ask why rubber brake hose is used at all, instead of always using braided stainless steel hose. The most typical reason is cost, but also use case. Braided stainless steel hose is typically more expensive than rubber. When the cost difference is extrapolated across hundreds or thousands of units, it is quite compelling to opt for the rubber option, especially when the use case exhibits that the operator will not need or want the additional capabilities offered by a brake system equipped with braided stainless steel brake lines. It thus stands to reason that braided stainless
