Product Description:

Spring Steel:

Spring steel is divided into two types, one is alloy spring steel, and other one is carbon spring steel.

Alloy spring steel is a type that is used for manufacturing springs and other elastic parts. Spring steel should have high elastic limit and ratio of yield strength and tensile strength to make sure that the springs obtain enough power of elastic deformation and can bear much load.

Types of alloy spring steel: Si-Mn spring steel, Si-Cr spring steel, Cr-Mn Spring steel, Cr-V spring steel and so on.

Usage/Applications of Hot Rolled Spring Steel

-55CrMnA Spring Steel possesses high strength, plasticity and toughness. Its hardenability is good. The thermal sensitivity is lower than Mn-steel. The decarburizing tendency is smaller than Si-Mn steel. The outstanding characteristic is the nice hardenability, moreover, hot workability, general mechanical properties and anti-decarburizing are also good.  

-It’s used for producing large flat spring o spiral spring with big diameter that can bear much load in the industry of cars and tractors.

 

Packaging & Delivery of Hot Rolled Spring Steel:

-Packing Detail:

1, The products can be packed in bundles by steel wires.

2, The weight of each bundle no exceed normally 3 tons

-Marks: there are two types of marks.

1, Tag marks. To show customers the specifications of products, company name and logo and other information required by customers.

2, Color marks. It’s easy for customers to distinguish them from other products at destination port.

-Delivery Detail: 30~45 working days after receive buyer’s T.T. or L/C.

 

Payment:

-Invoicing on theoretical weight or actual weight as customer’s request.

-FOB, CFR or CIF.

-Terms of payment: T.T. or L/C at sight.
