Metals in Modular Design: Stainless Steel and Aluminum

Stainless steel, often simply called inox, is an alloy of iron to which chromium and sometimes other elements such as nickel and molybdenum are added. This combination gives stainless steel its unique properties, notably its remarkable corrosion resistance and low maintenance. Stainless steel is classified into different families according to its composition: austenitic, ferritic, martensitic, and duplex. Each type has specific characteristics suitable for various uses. The exceptional corrosion resistance of stainless steel makes it indispensable in environments where moisture, acids, and other corrosive agents are present. For example, in industrial kitchens, stainless steel equipment and utensils are prized for their durability and ease of cleaning. Surfaces in contact with food must not only be resistant to chemicals and wear but also provide a hygienic surface. Stainless steel, with its smooth and non-porous structure, perfectly meets these requirements. In addition, stainless steel is widely used in the medical sector. Its anti-corrosive properties, combined with great strength and ease of sterilization, make it the material of choice for surgical instruments, medical implants, and diagnostic devices. Implants such as hip prostheses often use titanium and stainless steel alloys because they must not only be biocompatible but also withstand very strict conditions of prolonged use in the human body. The construction sector also takes advantage of the qualities of stainless steel. Whether for building facades, guardrails, or works of art like bridges and monuments, stainless steel offers excellent longevity and a lasting aesthetic appeal. Its ability to withstand weathering without needing frequent maintenance is particularly appreciated. The chemical and petrochemical industries are no exception to the intensive use of stainless steel. Storage tanks, pipelines, and other systems using corrosive materials must be constructed with materials that can withstand highly aggressive environments. Stainless steel provides this added security with, for example, alloys containing molybdenum for enhanced resistance. In summary, the characteristics of stainless steel in terms of corrosion resistance, durability, ease of maintenance, and hygienic properties make it a strategic material used in a multitude of industrial sectors.
