Stainless steel or inox steel (steel alloy) comprises 11% of the mass of chromium and an extreme 1.2% of the mass of carbon. It encompasses unpredictable amounts of carbon, silicon, manganese and some additional metallic materials such as nickel and molybdenum that are added to inculcate other expedient properties such as improved formability and resistance to corrosion. Its excellent corrosion-resistant property and tolerance to withstand high temperature in fabricating spacecraft components lead to longer durability of the component. Its high tensile strength and shear modulus make it more suitable for absorbing the impact stresses that landing gear equipment should endure (Martina 2019). The most abundantly recycled stainless steel worldwide is T-304, which can be weldable and machinable, and has better resistance to many chemical corrodents as well as industrial atmospheres and has well-known formability. Its austenitic structure offers excellent ductility and formability, which condenses work-hardening tendency and enhances suitability for deep drawing.
