Usi-sar 80 T steel has a strength limit of 800 to 950Mpa and a yield strength of MINIMUM 700MPa.
Thick steel sheets usi-sar 80 T and COSAR 80 T| ASTM A514 Grade B and ASTM A517 Grade B have a structure requiring high mechanical strength, where weight savings and moderate resistance to abrasion wear are very important.
Weldable structural hot rolled steel with high mechanical strength is used in structures in general, bridges, buildings, cranes, wagons, transmission towers, agricultural implements, floodgates, hydrogenerator components, earthmoving equipment and industrial machinery.
This family refers to usi-sar 80 steel, which are high-strength, low-alloy hot-rolled steels (HRBL), which can be translated into possibilities for reducing the weight of products obtained with these materials. Therefore, usi-sar 80 steel are suitable for large-scale assemblies and use in components of different structures.
In this group, the usi-sar 80 steel developed by Usiminas stands out to meet the requirements of high mechanical strength, good weldability, high efficiency of welded joints, moderate forming capacity and good resistance to abrasion. They can be supplied according to grades, namely: USI-SAR-50A and B, USI-SAR-55, USI-SAR-60-A, USISAR-65-A and usi-sar 80 steel with strength limits greater than 500, 550 , 600 and 650 MPa, respectively. Thicknesses from 6.35 mm to 150 mm
They are thick steel plates usi-sar 80 or COS AR 50/60/80 of high strength and abrasion resistant weldable steel, quenched and tempered steels with high mechanical strength and good toughness and with a strength limit of 500 to 720 MPa .
They are divided into two groups, according to the minimum flow limit of 460 MPa and 700 MPa, and applied in earthmoving equipment, cranes, pressure vessels, truck buckets and offshore platforms. The heat treatment of quenching by water curtain at 900°C, followed by tempering between 600 and 680°C, allows obtaining high mechanical strength combined with good toughness and weldability. The high mechanical strength and good toughness are its main characteristics, which allows promoting weight savings in conventional structures, which will be greater the greater the strength of the steel. They can also be indicated for applications in agricultural machines, armored cars and bridges.
