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.
