Heat treatment:
Tensile Strength Rm (Mpa): 1275 min
Yield Strength Rp0.2 (Mpa): 1180 min
Elongation A5 (%): 5 min
Area Reduction Ratio C (%): 25 min
FORGING:Hot forming temperature: 1050-850ºC.
SOFT ANNEALING: Heat to 640-680ºC, cool slowly in furnace. This will produce a maximum Brinell hardness of 255.
HARDENING: Harden from a temperature of 830-860ºC followed by oil quenching.
TEMPERING:Tempering temperature: 350-550ºC, air.
Mill′s test certificate:
EN 10204/3.1 with all relevant data reg. chem. composition, mech. properties and results of testing.
Application:
Spring Steel is typically used because of its' high yield strengths, resistance to deformation and its ability to return to its original shape.
