Steel is typically used for which of the following applications?

Steel is widely recognized for its strength and durability, making it particularly well-suited for high-pressure applications such as fittings. In environments where pressure levels are elevated, materials must withstand not just the pressure but also potential corrosion and fatigue over time. Steel possesses a high tensile strength, allowing it to maintain structural integrity under these demanding conditions.

High-pressure fittings are crucial in various industrial and mechanical contexts, where leaks or failures could have serious consequences. Steel's ability to handle high stress and resist deformation ensures a reliable seal in these applications.

While other materials like plastic or copper might be used in different contexts, they generally lack the same robust properties that steel provides for high-pressure fittings. For example, electrical wiring typically requires materials with good conductivity but less tensile strength, and low-pressure plumbing often can be made from lighter, less durable materials. Insulation materials focus on thermal resistance rather than structural integrity, further differentiating them from steel's primary applications.
