Spring Steel can be divided into two types. One is carbon spring steel, and other one is alloy spring steel.
Alloy spring steel is based on carbon spring steel, by adding one or more alloying elements to improve the mechanical properties, hardenability and other properties to meet the requirement for manufacture all kinds of spring steel.

-Percentage reduction of area: ψ (%): ≥30
-Hardness HBS, no heat treatment: ≤255
Usage/Applications of Round Spring Steel:
-ASTM1065, is medium-high carbon spring steel. After heat treatment, this type of steel obtains high strength, hardness and elasticity but this material isn’t perfect for welding.
-Its fatigue strength is equal to alloy spring steel when they are in same configuration.
-For manufacturing spring, spring circle, all kinds of grommet, clutch, and axels in the production of normal machine.
Packaging & Delivery of Round Spring Steel:
-Packing Detail: The products can be packed in bundles by steel wires.
-Marks: There are two types of marks. One is color mark and other one is tag mark. We paint color marks on both ends of bundles to make sure that it’s more convenient for customers to distinguish their products from other products at the destination port. The tag marks will be tied up to each bundle to make sure that customers know the specifications of each bundle like product’s name and size and other information of products.
-Delivery Detail:
1, Delivery time: 30~45 working days after receive buyer’s T.T. or L/C.
2, Delivery status should be written in the contract. (Heat treatment or no)
Transportation:
1, The products can be delivered by bulk vessel or by container. As for container, products with the length of 6m will be loaded in 20’ container, with 9m or 12m, in 40’ container.
2, The maximum quantity of loading of container is 25 tons.
3, The products are usually transported to the nearest port from the production place.
