What Kind of Steel is Alloy Spring Steel?
Alloy spring steel is based on carbon steel, by adding one or several alloying elements to improve the mechanical properties, hardenability and other properties of steel to meet the steel required for the production of various springs.
In addition, some steel grades, such as high-quality carbon structural steel, carbon tool steel, high-speed tool steel, and stainless steel, are selected as spring steels.
(1) Hot rolling (forging) Steels include hot rolled round bars, square steel, flat steel, steel plates, forged round steel and square steel.
(2) Cold drawing (rolling) Steel includes steel wire, steel strip and cold drawn steel (cold drawn round steel).
(1) Hot rolling (forging) steel
A. Delivery in hot rolled (wrought) condition The steel is thermoformed into a spring and then quenched and tempered.
B. Delivery in an annealed condition The steel is cold formed into a spring and then quenched and tempered.
All of the above should meet the requirements of the corresponding delivery state hardness.
