Spring Steel Flat Bar Flat bar are manufactured via rolling after billets are heated creating square-shaped products of appropriate toughness for spring materials. They are used in leaf springs for suspension systems on commercial vehicles like heavy duty trucks. Spring Steel Round Bar Admiral Steel - HR As Rolled SAE/AISI 5160 Alloy Round It is produced with a hot rolled round edge ideal for flat spring applications. Chromium aids wear and shock resistance and promotes better heat treat penetration. STANDARD SPECIFICATIONS:ASTM A689 & A304.

Heat Treatment of Spring Steels Metallurgy

Normally, the steel could be used up to 25 mm thickness for flat products and 35 mm diameter for round products. Forging of the steel starts at 1050°C to, finish at 850°. Hot forming to require spring shape is done at 900-820°C, and then sub-critically annealed at 640 to 700°C to have a hardness of 225 BHN.

Spring Basics from Eaton Spring Hotrod Hotline

Multi-Leaf springs consist of heat-treated flat steel bars of diminishing lengths formed to a predetermined arch held together by a bolt through its center. Mono-Leaf springs consist of only one heat-treated plate of steel whose thickness is uniformly tapered from the center to each end.
