At Hierros Mora Antón, we work every day with one of the most versatile and resistant materials in existence: steel. It is present in structures, machinery, industrial furniture and construction systems, and has been part of our company’s DNA for decades. However, not all steel is the same. Beyond structural steel or common stainless steel, there is an exclusive category of alloys so sophisticated that they can cost thousands of euros per kilo. These are known as high-performance steels, developed for the military, aerospace and luxury industries
Steel is, in essence, an alloy of iron and carbon. But when elements such as nickel, molybdenum, cobalt or titanium are added, the material achieves extraordinary properties: tensile strength, thermal stability, ductility and corrosion resistance in extreme conditions. Manufacturing these special steels requires highly controlled processes, vacuum melting and precision heat treatments that only a few laboratories in the world have mastered.
One of the most emblematic examples is maraging steel, used in the manufacture of missile components, turbines, and aircraft fuselages. Unlike conventional steel, maraging steel maintains its strength even after undergoing significant deformation, making it a strategic material with restricted use. Its price can exceed £850 per kilo, an unthinkable figure for standard industrial steel.
In the aerospace sector, we find special grade stainless steels such as 15-5PH or 17-4PH, capable of withstanding extreme thermal variations without losing stability. These alloys are used in rockets, satellites and aircraft engines, where reliability is a matter of life and death. Their purity and quality control are so high that even the slightest impurity could compromise an entire space mission.
And although it may seem surprising, steel is also associated with luxury. In Swiss watchmaking and high-end automotive manufacturing, steels such as 904L —more resistant and with a distinctive shine— are used, requiring manual machining and polishing processes. In some limited-edition watches, the value of steel even exceeds that of gold, not because of its composition, but because of the precision and finish required for its manufacture.
At Hierros Mora Antón, we understand the value of steel in all its forms: from the most common and functional to the most advanced alloys. That is why we are committed to quality, innovation and technical knowledge as the basis of our service. Far from being an ordinary material, steel remains a symbol of progress and industrial excellence. And in its most exclusive versions, it proves that even an everyday metal can become a true technological gem.
