Surgical stainless steel Surgical stainless steel Surgical stainless steel is a grade of stainless steel used in biomedical applications. The most common "surgical steels" are austenitic 316 stainless and martensitic 440 and 420 stainless steels. There is no formal definition on what constitutes a "surgical stainless steel", so product manufacturers and distributors apply the term to refer to any grade of corrosion resistant steel. 316 stainless steel, also referred to as marine grade stainless steel, is a chromium, nickel, molybdenum alloy of steel that exhibits relatively good strength and corrosion resistance. Along with the titanium alloy Ti6Al4V, 316 stainless is a common choice
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
