The following bibliographic material is provided to assist you with your purchasing decision:This specification covers cold-rolled carbon steel strip in cut lengths or coils, furnished to closer tolerances than cold-rolled carbon steel sheet. The steel shall be made by the open-hearth, basic-oxygen, or electric-furnace process. Cold-rolled carbon strip specified to temper numbers shall conform to the Rockwell hardness
Alloy Steel 4130 - Wingate Alloys Inc
Principal FeaturesApplicationsMachinabilityFormingHeat TreatmentHot WorkingAnnealingTemperingPhysical PropertiesAISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment.Martensitic Stainless Steel Stainless Steel Products This is the steel for cold forging focusing on quenching and tempering hardness more than LAK41. Harness is higher than LAK41 and HRC58 to 60 can be obtained by low temperature tempering. Corrosion proof is slightly lower than LAK41. Cold workability shows the same characteristics as SUS 20J2 at the state of globular tempering.

The formability of all steel products is a result of the interaction of many variables. The variables include:the mechanical properties of the steel, the forming system (tooling) used to manufacture parts, and the lubrication used during forming. AK Steel can directly affect the mechanical properties of the steel.

Heat Treatment of Spring Steels MetallurgyNormally, 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. Normalising is done at 850 to 880°C.
