Product Specifications:

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 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.

 

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: How do we guarantee the quality of our products?

A2: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q3: How soon can we receive the product after purchase?

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.

Q:Is the coil strip? Is hot rolled coil and hot rolled strip the same?
As for the "Q235" mentioned below, this steel can not be deformed under the pressure of 235 MPa and is used to represent the material of steel. Similarly, Q195 is naturally deformed at 195 MPa pressure.
Q:What is the difference between galvanized steel cold base galvanized steel strip and hot galvanized steel strip?
In addition because of the high density of zinc, galvanized steel coating with the same aluminium zinc plate in the price there is no advantage, because the control relationship between zinc flower, zinc plating is more difficult to control, and anti oxidation performance and ALuminum zinc is poor compared to several times, so now mainly in the aluminum zinc as the main building materials and its the performance is 3-4 times of zinc, but the current electronics industry because of influence of hot dip galvanizing plate conductivity, appearance or using mainly low coating, building materials mainly to hot-dip aluminum zinc 100g/ square meters above. The main hot dipped aluminum zinc is 55%AL and 44.5%Zn.
Q:What are the differences between strip steel and round steel? Where are they mainly used?
Difference between round bar and other steel bars:(1), is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other.(2) the composition is different. Round steel (grade a steel) belongs to ordinary low carbon steel, and most other steel bars are alloy steel.(3), the strength is not the same, low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:What is the difference between strip and coil?
The strip and the coil is the main raw material for the production of welded steel pipe, the steel pipe manufacturing is mainly manufacturing process for spiral welded pipe used for steel roll uncoiling, leveling, trimming, molding, welding, welded pipe must be used for sheet forming and welding, if the steel roll uncoiling leveling must also be cut into leaflets the use of steel plate.
Q:What's the meaning of "double light" in strip cold rolling?
Strip strip coiling: general supply, with high dimensional accuracy, good surface quality, easy processing, material saving and other advantages. With the same steel plate, strip by strip material is divided into ordinary and high quality strip two; according to the processing method of cold rolled strip steel hot strip, two.
Q:Hot rolled strip and hot rolled strip are also sealing plates? What's their function?
First of all, there are some hot rolled strip, the main role is to prevent roll cooling water flow to the workpiece, affecting the crown of the strip and shape control.
Q:Can the tension leveller eliminate the wave shape of strip steel completely?
We take the longest and shortest fibers in the cross section of the strip and analyze their elastic and plastic deformations under the action of tension. In addition to external force because of tension by strip in straightening process, and bending stress and bending stress is tensile stress and compressive stress of the component, and the main role is tensile stress, the main deformation so through the analysis of tensile deformation on behalf of strip.
Q:The degreasing time is too long, will the strip surface be oxidized?
Galvanized steel plate in spray, generally do phosphating treatment, the parameters of free acid phosphating solution should be kept low, and high temperature, acid, zinc ions reduced excessive reaction, resulting in coarse crystallization. Reference: Fa:0.8-1.5 Ta:17-28 acid ratio of about 25, the temperature can be 35-45 degrees.
Q:Is the strip steel strip?
The steel can be divided into sheet, strip, wire, profiles, tubes and other categories, collectively refers to the strip steel sheet and strip, it only refers to the shape and thickness, classification, processing methods (hot rolled) is Never mind, the difference is that the material delivery requirement is size length * width * thickness. The strip, the strip is measured for delivery size thickness * width * L (where L is not required to provide, usually coiled strip) delivery.
Q:What is galvanized steel strip? What's the difference between galvanized strip and cold rolled strip?
Galvanized steel strips are cold-rolled or hot-rolled, long and narrow strip steel plates coated with different layers of material called zinc. Hot galvanizing has the advantages of uniform coating, strong adhesion, long service life and so on.
