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 ratio of yield strength and tensile strength and elastic limit 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.
Specification of Spring Strip Steel:
-Standard: GB/T 1222-2007
-Type: Spring Steel
-Yield Strength σs (MPa): ≥1470 (150)
1, Hot rolled + Heat treatment, ≤321HB
2, Cold drawn + Heat treatment: ≤321HB
-Impact Power: ≥40
Norm of heat treatment:
1, Quenching: 1050℃~1100℃.
2, Cooled by oil.
3, Tempering: 600℃±50℃.
Usage/Applications of Spring Strip Steel:
-Due to the elements W, Cr and V, this type of spring steel obtain pretty high hardenability and nice mechanical properties under room temperature and high temperature. The tempering stability and hot workability are good.
-Being used under the state of quenching and high temperature tempering. It’s usually used as heat-resisting springs with working temperature below 500℃, like main secure valve spring of furnace and turbine steam seal leaf springs.
Packaging & Delivery of Spring Strip Steel:
-Packing Detail: The products will be well packed.
-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.
