SAE 304 stainless steel optimal high temperature strength. The carbon content of 304L (UNS 30403) is restricted to a maximum of 0.03%, which prevents sensitization during welding. Sensitization is the formation of chromium carbides along grain boundaries when a stainless steel is exposed to temperatures in the range of ~–. The subsequent formation of chromium carbide results in reduced corrosion resistance along the grain boundary leaving the stainless steel susceptible to unanticipated corrosion in an environment where 304 would be expected to be corrosion resistant. This grain boundary corrosive attack is known as intergranular corrosion. The carbon content of 304 (UNS 30400) is restricted
Braided stainless steel brake lines tubing such as galvanized or stainless steel pipe, as this would prevent any expansion along the hydraulic fluid path, providing the most direct transfer of operator input force to the friction surfaces, and in fact most of the length of a brake line is made of stainless steel. However, hard tubing will not endure the motions caused by articulation of suspension components. For example, an automobile wheel is not hard-mounted to the automobile's frame or unibody chassis. It is instead mounted to a suspension component which allows that wheel to move in response to road irregularities and steering inputs. Because
