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.
Specification of Spring Steel Strip
-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.

A3: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.
Q4: What makes stainless steel stainless?
A4: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.
Q5: Can stainless steel rust?
A5: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.
