Heat treatment Related

Annealing of SUP9 Spring Steel

Slowly heated to 740-770 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The SUP9 tool steel will get MAX 250 HB （Brinell hardness）.

Hardening of SUP9 Spring Steel

SUP9 steels should be heated uniformly to 830-860°C (1526-1580°F) until completely heated through. About 30 min per 25 mm of ruling section is to be provided and then the steels should be immediately quenched in oil.

Tempering of SUP9 Spring Steel

Tempering of SUP9 steels is performed at 460-510°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness.

Mechanical Properties

The mechanical properties of SUP9 Spring Steels are outlined in the following table.

Tensile strength Conditions to yield strength Elongation Reduction of area Hardness (Hot Rolled) Hardness (Cold Drawn)

σb (MPa)：≥1225(125) σ0.2 (MPa)：≥1080(110) δ5 (%)：≥9 ψ (%)：≥20 ≤321HB;

Applications

SUP9 steels, Highlight the advantage is good hardenability, another hot working performance, comprehensive mechanical properties,

Decarburization resistance is also good big cross section of various important spring, such as automobile, locomotive, large plate spring, spring, etc. SUP9 Spring main used for heavy vehicles, tractors, industrial production load, stress and the diameter of the larger plate spring and helical spring
