Tensile Strength Properties of Aluminum and Stainless Steel

Note: Mild steel = 55 ksi = 55,000 psi (some people use 60 ksi for easier calculation)

Aluminum Plate Rolling

How to use this tensile strength of metals information for bending aluminum or stainless steel:
Divide 55 ksi by the tensile strength number associated with the type of aluminum or stainless steel you use (the answer will be >1 for aluminum and <1 for stainless steel). Multiply the answer by the mild steel capacity of your machine to get the corresponding capacity of the machine. Be sure to adjust the settings of your machine for the actual metal thickness you are bending. Extra room for a radius is required when bending with a hand brake or hydraulic leaf brake.

  • Tempers T361 and T861 were formerly designated T36 and T86, respectively.
  • For stress-relieved tempers, the characteristics and properties other than
    those specified may differ somewhat from the corresponding characteristics
    and properties of the material in the basic temper.
  • 1 ksi = 1000 psi
