High wear resistance steels
These are high-strength, alloyed, quenched, and tempered wear-resistant steels, ideal for all types of applications requiring high wear resistance, such as industrial tools and machinery.
AT 13% Mn
This is a wear-resistant austenitic Mn steel. It is supplied in an austenitic or hypertempered state, heated to over 1000°C and rapidly quenched in water. This results in an austenitic structure with a strength of approximately 100 Hg/mm2, with good toughness and elongation. It undergoes a self-hardening process on its surface due to friction or impact, a property that gives it great wear resistance.
Utilization:
Shot blasting machines and their spare parts, hammers, jaws, cover plates in mills and crushers, hammers in the cement, ceramics, and mining industries, railway switches, wear plates, electromagnet constructions.

Utilization:
For all applications subject to moderate wear caused by impacts or continuous friction caused by hard particles such as stones, gravel, sand, minerals, ferroalloys.
HB-400
HB-400
It is a tempered and annealed alloyed wear-resistant steel characterized by its resistance to abrasion and impact, as well as its high mechanical strength, good formability, and excellent weldability, making this steel the most widely used for all types of applications.
Use:
For all applications subject to high wear caused by violent impacts or continuous and extreme friction caused by hard particles such as stones, gravel, sand, minerals, ferroalloys, coal, dust, etc.
HB-500
HB-500
This is a tempered, alloyed, and annealed wear-resistant steel characterized by its extreme resistance to abrasion and impact. Its high mechanical strength and good weldability make it optimal for extreme situations involving high stresses, impacts, and severe abrasions.
Use:
For all applications subject to high wear caused by violent impacts or continuous and extreme friction caused by hard particles such as stones, gravel, sand, minerals, ferroalloys, coal, dust, etc.
High tensile strength steels
It is a high-yield steel, quenched and tempered, characterized by a guaranteed yield strength of 700 or 890 Nw/mm2 accompanied by high mechanical strength and good toughness, making it ideal for all types of constructions subject to high static or dynamic mechanical stresses.
AU-690
It is a high-yield steel, quenched and tempered, characterized by its guaranteed yield strength of 700 N/mm2 accompanied by high mechanical resistance and good toughness, making it ideal for all types of constructions subject to high static or dynamic mechanical stresses.
Use:
Due to its high hardness and elastic limit, its use is recommended in machines or welded constructions subject to high mechanical stresses that can be of either static or dynamic origin.
Construction of hangars, ventilators, cyclones, and heavy-duty turbines, mobile crane components, chassis, telescopic booms, backhoe arms, and wheel loaders, joining elements subject to combined forces, bridge components, and lightening of metal structures by reducing dead weight.
AU-890
It is a fine-grained, high-yield steel, quenched and tempered, characterized by its guaranteed yield strength of 890 N/mm2, accompanied by high mechanical strength and good toughness, making it ideal for all types of construction subject to great static and dynamic stresses.
Utilization:
Due to its great resistance and high elastic limit, its use is recommended in machines or welded constructions subject to high mechanical stresses that can be of either static or dynamic origin.
The interest in high-strength steels is particularly important given that not only the production cost, but also the operating and productivity costs of a construction are affected by the mechanical characteristics of the material.
The profitability of the steels described has been particularly demonstrated in the manufacture and repair of mobile and fixed cranes, hoisting machines, earthmoving machines and heavy vehicles, rippers and complete shafts for bulldozers, hooks for handling large blocks in quarries or ports, large dumpers, and heavy industrial fans. For all types of earthmoving and public works machinery.
