Automotive bodies

The Allegheny Ludlum Corporation worked with Ford on various concept cars with stainless steel bodies from the 1930s through the 1970s, as demonstrations of the material's potential. The 1957 and 1958 Cadillac Eldorado Brougham had a stainless steel roof. In 1981 and 1982, the DeLorean DMC-12 production automobile used stainless steel body panels over a glass-reinforced plasticmonocoque. Intercity buses made by Motor Coach Industries are partially made of stainless steel. The aft body panel of the Porsche Cayman model (2-door coupe hatchback) is made of stainless steel. It was discovered during early body prototyping that conventional steel could not be formed without cracking (due to the many curves and angles in that automobile). Thus, Porsche was forced to use stainless steel on the Cayman.

Passenger rail cars

Rail cars have commonly been manufactured using corrugated stainless steel panels (for additional structural strength). This was particularly popular during the 1960s and 1970s, but has since declined. One notable example was the early Pioneer Zephyr. Notable former manufacturers of stainless steel rolling stock included the Budd Company (USA), which has been licensed to Japan's Tokyu Car Corporation, and the Portuguese company Sorefame. Many railcars in the United States are still manufactured with stainless steel, unlike other countries who have shifted away.

Aircraft

Budd also built an airplane, the Budd BB-1 Pioneer, of stainless steel tube and sheet, which is on display at the Franklin Institute.

The American Fleetwings Sea Birdamphibious aircraft of 1936 was also built using a spot-welded stainless steel hull.

The Bristol Aeroplane Company built the all-stainless steel Bristol 188 high-speed research aircraft, which first flew in 1963.

The use of stainless steel in mainstream aircraft is hindered by its excessive weight compared to other materials, such as aluminum.

Q: How do you calculate the flow rate in stainless steel pipes?: To calculate the flow rate in stainless steel pipes, you can use the principles of fluid dynamics and the properties of the fluid flowing through the pipe. There are several factors that should be taken into consideration: 1. Determine the diameter of the pipe: The diameter of the pipe will affect the flow rate since a larger diameter allows for a greater volume of fluid to pass through. 2. Determine the viscosity of the fluid: Viscosity refers to the resistance of a fluid to flow. Fluids with higher viscosity will flow more slowly, while fluids with lower viscosity will flow more quickly. 3. Calculate the pressure drop: The pressure drop across the pipe is an important factor in determining the flow rate. This can be calculated using pressure measurements at different points along the pipe. 4. Use the Reynolds number: The Reynolds number is a dimensionless quantity that combines the fluid velocity, density, viscosity, and pipe diameter. It helps determine whether the flow is laminar (smooth) or turbulent (chaotic). There are different equations to calculate the Reynolds number depending on the flow regime. 5. Apply the appropriate flow equation: Depending on the flow regime, you can use different equations to calculate the flow rate. For laminar flow, the Hagen-Poiseuille equation can be used. For turbulent flow, the Darcy-Weisbach equation or the Manning equation can be used. By considering these factors and applying the appropriate equations, you can calculate the flow rate in stainless steel pipes. It is important to note that these calculations provide an estimate and may not be exact due to various factors such as pipe roughness, fittings, and other obstructions in the pipe. Therefore, it is recommended to consult with a fluid dynamics expert or use specialized software for accurate calculations.
