Period 4 element in period 4, between chromium and iron. Manganese is often found free in nature, but is also found in combination with iron. Manganese, like chromium before it, is an important component in stainless steel, preventing the iron from rusting. Manganese is also often used in pigments, again like chromium. Manganese is also poisonous; if enough is inhaled, it can cause irreversible neurological damage. Iron (Fe) is an element in period 4, between manganese and cobalt. Iron is probably the most well-known element in period 4, being the most common element in the earth and a major component of steel. Iron-56
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
