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 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
