What is SAE5160 Spring Bars?

 

Compare to silicon manganese steel, SAE5160 spring steel has higher strength, higher plasticity and better toughness, better hardenability, lower overheat sensitivity, less decarburization tendency and greater temper brittleness. ASTM5160 is used in the vehicle and tractor industries to produce heavy-duty, leaf springs and coil springs with large diameters.
