Standard spring steel wire and uses

Standard spring steel wire in our country is based on an ISO and JIS standard, set by the steel. existing national standards and recommended industry standards including carbon spring steel wire, 6 4 spring steel alloy spring steel wire standard spring steel is widely used in, the largest amount of steel. of manganese in steel carbon with 0.60%~0.90% and 0.3%~1.20%, not to add additional alloying elements, using a relatively low cost.


Carbon spring steel wire or processing by appropriate heat treatment, you can get very high tensile strength, enough toughness and good fatigue life. but the hardenability of low carbon steel wire, relaxation properties and corrosion-resistant performance is poor, young's modulus temperature coefficient (up to 300x10-6/), applies to the manufacturing section is small, low working temperature (120 ℃ >) spring.
