Product Description:

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 manufacturing all kinds of spring steel.


Specification of HR Spring Steel:

-Material: 65Mn

-Standard: GB

-Type: Spring Steel


Chemical Composition:


















Mechanical Properties:

-Tensile Strength σb (MPa): 825~925

-Yield Strength σs (MPa): 520~690

-Elongation δ10(%): 14~21.5

-Percentage reduction of area: ψ (%): ≥10


1, Hot rolled: 240~270HB

2, Soft state hardness of cold rolled: 190~220HB

3, Hard state hardness of cold rolled: 300~340HB

4, Heat treatment: 38~60HRC


Usage/Applications of HR Spring Steel:

-65Mn, element Mn improves hardenability. Surface decarburizing tendency is less than silicon steel. After heat treatment, the mechanical properties are better than carbon steel.

-Spring steel of this material is usually used as flat and round spring of small size, clockwork spring, spring ring, valve spring, brake spring and so on.


Packaging & Delivery of HR Spring Steel:

-Packing Detail: The products can be packed in bundles by steel wires.

-Marks: We will paint both ends of each bundle of products to make sure that it’s more convenient for customers to distinguish their products from others, besides, we will tie tag marks to the bundles with following information: company name and logo, product name, specification, material, and so on.

-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)



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.
